Since last thursday (19/08/2008), have had the most appalling connection speed I think I've ever had while on IDNET. Prior to this i've had the odd outages in the past.. but those were very very rare occasions.
Just done some broadband speed tests this morning, and i'm finding that my 'up to 8mb' service is currently performing as a 128k (twice the speed of a dialup modem) connection. A download i tried from cisco/linksys of a firmware upgrade for my router (86mb file) quoted me 2 hours+ for the download and never got above 15.9k/sec.
Did a broadband speedtest from ZDNET: 4008 kbits took 31 seconds to perform. That was half of a 256k connection on the bar graph comparison it shown.
Now I play Age of Conan, and found that from thursday night its been simply unplayable due to this.
When this first happened, i logged onto my idnet account and checked the status of the servers etc, all shown as 'good', and when i looked at my account, it shown the latest invoice as unpaid (18th of June).. strange i thought? because the C/Card details are for a card that not only has no problems whatsoever, but its also a valid card until mid 2009..
So anyway, used another card, payment immediately authorised, and the account as of checking right now shows as PAID.
So i guess what i desparately need to know is this: Do IDNET cap your broadband speed for any reason like this without trying to make contact first ? I just find it a bit.. funny.. that it seems to be purposely set at the 128k mark.. almost like an emergency webbrowsing mode?
Any ideas anyone?
Welcome to the forum. :welc: :karma:
No, IDNet would have contacted you, they never cap.
Can you post your router stats - downstream attenuation, noise margin and sync speed. Also, if possible, get a BT test and post the results of that. ATM, it sounds to me like you have a very low profile, possibly due to a line fault.
:welc: :karma:
As Rik says really. IDNet do not cap. Please post stats and do a BT speed test - I suspect instability has caused your profile to drop to 135k, but that's just a guess. :)
Hi,
:welc: :karma:
Sorry to hear about your problems. As Rik and Sebby state this is definitely not IDNet's doing. First quick check... Have you plugged in anything new to the phone line recently? New phone? Cordless? Fax? Sky box?
Which make and model of filters do you have? How old are they? Do you have one in every socket? Has someone plugged something in without a filter?
Which modem do you have and how old is it?
When you make voice calls what is the quality of the line like? Does it crackle or is it noisy in some other way?
Cheers,
Paul.
Sorry for the delay, been busy trying to get this going, testing with another router, a new telephone cable, new filter... no further success... thanks for responding so far, hope this further info gives some clues.
Ok set up is as follows:
Main BT socket is downstairs in the hall. Plugged into that is the router, filter and the only telephone for the entire house.
Telephone is not crackly in any way and is crystal clear. Telephone when in use also does not disrupt the internet. This suggests the filter is working correctly. I have however tried another filter since this 'problem' and the problem is still present.
Ran the speedtest from BT about 10 mins ago:
Test1 comprises of Best Effort Test: -provides background information.
IP profile for your line is - 135 kbps
DSL connection rate: 832 kbps(UP-STREAM) 5760 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 91 kbps
There was a 2nd test it suggested which was to change the login on my dsl to bt_test_user which i did at router level because the 2nd test 'seems' to be for users who dial up on dsl? anyway, the router connected but the 2nd test just got page cannot be displayed, nor could it see any other webpage either, so couldn't proceed with test 2.
IP profile for your line is - 135 kbps - is I think the concern. The only time i've disconnected any equipment from the line recently has been since this problem occurred.
Tested with 2 DSL routers
1: Linksys WAG54GS and
2: Netgear DG834PN)
Also i went out and bought ANOTHER telephone extention (DSL Approved), and the results are exactly the same.
I rang IDNET 'out of hours support', and spoke to I presume one of their engineers, however i'm guessing he rang me back from home or something because i could hear children in the background, i was told that the problem was most likely to be the profile, and that i now have to wait the entire weekend until monday for BT to do something about this? I'm also presuming now that they meant BT Wholesale. I came off that phone call feeling proper down, with the prospect of my entire weekend off ruined.. i rang bt anyway who contacted BT wholesale to see if there was any reason IDNET could not call them. There was definitely someone at BT wholesale according to bt as they rang them up.. and so i passed this info back to IDNET who then proceed to tell me that the reason i now have to wait until monday is because whatever service it is that allows them to raised problems with BT wholesale at weekends costs an extra £10 a month???
Now further:
My Netgear router is my old router and i did replace this with the linksys one which has been absolutely fine, giving me 67ms in Age of Conan with the 'odd spike' now and again which many players of that game reported anyway, but my netgear router has this info if it helps:
ADSL Link Downstream Upstream
Connection Speed 5760 kbps 832 kbps
Line Attenuation 38.0 db 22.0 db
Noise Margin 14.5 db 12.0 db
Filters that i've got are:
Z-Blocker Z-420UK-A and another which sorry hasn't got any determining make/model on it. Sorry.
Basically the way it 'looks' at the moment, its the IP Profile thats caused this? with the exception of changing the telephone extention cable to the router (as its upstairs), no other disconnections have been done. but to have been aggressively forced onto this horrid 135k connection for an entire weekend has rather depressed me. Picked a bad week to give up smoking :/ day 3 and now i wish i hadn't stopped.
Sorry, forgot to mention, the only reason i changed the extention cable in the first place was because i was getting 4000 downstream approx, so wanted to try to rule out noise/interference etc.
I'd really like to sort the problem out, so was just covering bases.
The IP profile is to blame (something outside IDNet's control). It's most likely set at 135k due to instability, which I'd say is confirmed by the fact that your SNRM is 14.5dB, suggesting a 15dB target SNRM set by the exchange in an attempt to combat this.
You mention that this only happened on Thursday, so you probably had a "one-off" surge of noise that caused several re-syncs. Not only had this affected the profile, but the target SNRM (unless this happened at an earlier time if your line has been unstable in the past). Going by your attenuation, I'd say you could get full sync if the target SNRM was the default 6dB, but this is something we can address later on once the profile is sorted.
The profile should recover by itself in about 3 days, assuming your sync is stable. Have you checked the logs to see if you've lost sync since Thursday?
Otherwise, IDNet can get this reset by BT on Monday. :)
Firstly, thank you. It is very much appreciated that you took the time to reply and indeed to state your intention to perhaps help later on once this particular issue is sorted.
I've installed RouterStates Lite (v2.7b) which is now monitoring the noise margin(db) and connection speed and it seems to be updating its graphs now ever 3-4 minutes or so, might be handy for monitoring peaks etc.
So you know the level of my computing, i'm a desktop support engineer for a large corporate, so please feel free to be techy with me, if i don't understand something, i'll definitely say so :)
I moved into the current house around feb/march of last year, and to be honest, i've never once had as good a connection at this house as i had at the last, and now seeing the noise(db) etc, do you think this could be the reason why?
The house is relatively new (10 years old), and i've not really looked inside the master socket at the pairing at all, but looking at the guides shown on this rather useful (if i may say so) forum, could it be that the master socket may contain part of the reason for excess noise? I've routed my telephone extention so it doesn't pass any power points, and ensured no damage done while installing it too, am quite happy to buy yet another extension from any recommended source however and install that instead.. they don't look like they have incredible shielding on these extension cables, they are kind flat'ish. The last one i bought from maplin which said it was adsl approved and well, you kind buy based on that half the time..well at least i did anyway :)
I agree with Sebby that you appear to have had a burst of noise which was bad enough to both depress your profile and push up the target noise margin. IDNet can do something about the former on Monday, if it hasn't already righted itself, however, reducing target margins is something that BT don't like to do manually. Instead, theoretically, if you maintain sync for 14 days, the target NM will drop to 12db, repeating in 3db steps. However, IDNet can run a woosh test, and if they can see a line fault, once that has been resolved, they stand a chance of getting bT to move the margin.
What you were told was correct, btw, to get this kind of fault looked at over a weekend requires you to have 'extra care' at £10pm. :(
hi,
OK. What appears to have happened is your router repeatedly lost sync and the software (DLM) in the exchange that manages line stability has started knocking your profile down and your target signal to noise margin (SNRM) up in order to stabilise your line and stop the router dropping and resyncing. Unfortunately this process appears not to have been successful and it's kept going down until it hit the bottom stop. Disconnecting your modem repeatedly may also cause the exchange to think the sync is being lost and prevent recovery. Some routers give a "last gasp" signal to say they're going down when you pull the power out of them so the exchange knows it's not a loss of sync so it's good advice to always pull the power out of the modem before disconnecting the phone cable.
The sync speeds are the actual speeds the router is working electrically with the exchange at. The profile is an artificial limit put on the speed by the exchange software so that it doesn't try to pour more data down the line than can reasonably be carried (including errors) so that the whole system doesn't descend into TCP retransmission hell. If a profile gets knocked down but the line quality improves and the sync recovers and is consistent thereafter the exchange will slowly knock it back up. Depending on how different the sync and profile are this may take up to 5-6 days (it often recovers quicker from large changes and these are interpreted as being due to some noise event that is now over.) Unfortunately I don't think this will recover much during the weekend. The fact that you've had this sync drop does tend to imply that the new cables aren't good for ADSL and should go. Is your master socket one of the new NTE5a sockets (the ones with the line across the centre which you can remove the bottom half of if you take the screws out?
As a quick test I would take the modem downstairs to the master socket, unplug everything from the socket then (if it's an NTE5a) remove the screws and take the bottom half off. Then connect the filter and modem to the "test socket" behind. See what kind of sync you get then. If it improves significantly then your extension wiring is an issue.
Oval or flat extension cables are generally a bad idea as the pairs inside them are laid flat rather than being twisted so they lose the ability to reject interference that may mess the signal up. If I have to extend a phone line that carries ADSL I always use CAT5 cable (I'm sure you probably have a box kicking around at work ;) .) Additionally extensions on a reel form lovely coils that pick up RF beautifully. My friend put their ADSL router on a 25m ultraflat extension reel (most of which was still on the reel) and wondered why they only had a 750k profile when their neighbours had megs.
To get the best out of your line I would do the following:
1)All filters are not created equal. I would buy an ADSLNation XTE2005 filtered faceplate (assuming you do have an NTE5a master socket - If not BT will come and change your master socket to an NTE5a for you for £30) http://www.adslnation.com/phpapps/catalog/product_info.php?cPath=24&products_id=105 These are pro-grade ferrite filters and will give you the best isolation and impedance match to the line. Unless you have a Sky box you won't need filters on the other socket(s) any more.
2) Most cables supplied with routers are the cr*ppy flat ones. I would buy an ADSLNation professional twisted-pair modem cable to connect the modem to the socket. http://www.adslnation.com/phpapps/catalog/index.php?cPath=21 (or knock one up yourself if you have some CAT5 and a couple of RJ11s) The only pins that need connecting are the centre pair. If you want to stay with soap-on-a-rope filters I would go with a set of ADSLNation XF-1e filters. http://www.adslnation.com/phpapps/catalog/product_info.php?cPath=24&products_id=54
3)Move your router downstairs and site it next to the master socket. Run the Ethernet upstairs on CAT5 (or a Devolo mains networking rig) and put a switch up there.
4)Disconnect the ring wire (pin 3) in all your phone sockets. 90%+ of phones will work without it and it acts as an antenna for interference as it's not balanced.
Good luck, Let us know how you get on.
Cheers,
Paul.
Well spotted, Paul. The way I read reply #4 initially was that the router was plugged into the socket in the hall, I missed the extension lead. This has to be a prime suspect, particularly if the connection to the router is not run with proper twisted pair cable.
Ah yes, I missed that too. As Paul says, a filtered faceplate is a sure way to get the connection the best it can be on your side of the fence, so to speak. :)
sorry to hijack this thread but Paul mentioned about the standard cables with routers and making one up with some CAT5. Is this the same cable as used for router to computer just with different ends fitted?
I know this wont help Gyruss in anyway but I see similarities in what he says with a problem I have had over the past few months. Dropped connections, slow speeds etc. have had BT out twice in the last month and sure enough when they get here the line has picked up and they never find anything wrong. a week after they called it went again, my ISP, not IDNet BTW, told me that they will get them out again but just had the same result in that they couldnt find a fault. A pattern seemed to be formimg with this as it too went on a thursday or friday and was like that all weekend, one time over a bank hol so was down till a tuesday, they told me the BT cover costs £15 p/m though.
I use a Netgear DG834PN too. It has always been good for me until this prob but I still dont think its the router. When I first went on MAX package I got results like this
IP profile for your line is - 7150 kbps
DSL connection rate: 448 kbps(UP-STREAM) 8128 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 6667 kbps
from BT tester constantly even after manual disconnects it re-synced at that and would hold it for months, after this prob I get this
IP profile for your line is - 5000 kbps
DSL connection rate: 448 kbps(UP-STREAM) 6112 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 4550 kbps
which doesnt seem right to me ??? but they see no fault, its above the fault threshold so its 'ok'. BT fiddled about and made it worse, in my view.
anyway sorry for the hijack and hope you get it sorted soon, not an expert but it does sound like a line fault that will 'put itself right'. You will have tried this already but I used to disconnect and power down the router for 20mins or so and see if that worked.

Yes. It's the same cable with RJ11 plugs (the small ones) fitted. Pin 1 and 6 aren't present on the plug so you see 4 pins (2,3,4 and 5). Connect the middle two (3&4) on one end to the middle two on the other using one pair (e.g orange and orange-white) of a piece of CAT5. I usually connect 3 to 4 and 4 to 3.
Cheers,
Paul.
Thanks Paul.
can you get better quality cable and fittings then or is it all the same
There's various grades of cable. I haven't done any research but the frequencies used by ADSL are relatively low and only on one pair so I'd imagine anything CAT5 or above should do it just as well. Just make sure the conductors are solid not stranded. From what I've seen connectors are much of a muchness.
Cheers,
Paul.
Ok, I tested the netgear router in the hall, connected directly to the BT master socket.
ADSL Link Downstream Upstream
Connection Speed 5760 kbps 832 kbps
Line Attenuation 38.0 db 22.0 db
Noise Margin 14.8 db 12.0 db
This effectively I hope shows that the problem is not with the extension cable(s) that i ran up the stairs?
I've since checked so many things now, with absolutely nothing coming up as conclusive. I need to keep costs down trying to fix the issue however as we have a new baby in the house so guess where my money goes :)
Anyway, 2 routers tried, 1 tested in the hall with a 'shielded' cable round/twisted that connects between the router and the filter, tried 2 different phone extensions for the 'upstairs' connected scenario.. and the only thing left through all of this is the plain and simple fact..
the IP profile being set at 135k.
Is there anything that can be set by the ISP & BT to take into account the noise(db) ? something that will mean the sync won't be lost as much? i'm only 1.6km from the exchange too, you'd think i'd be ok.
Its not like i'm after the magical 8192 downstream either, i can manage just fine with 5000-6000, but 135? I think i'd rather move house again and go cable if i was forced to stay on that :)
Don't worry, the profile will take a maximum of 5 days to lift, and because yours is a large increase it should happen sooner. Either way, if it is still low on Monday i would give support a ring and ask them to speak nicely to BT! Enjoy the rest of your weekend off!

Testing the router in the master socket is, believe it not, the same as trying in an extension socket, as it forms part of the loop. If you take the bottom panel off the master socket carefully, there is another socket behind (the test socket). This is where the line comes into the house, and will allow you to test the connection excluding extension wiring from the equation.
Hi,
The fact that your sync has stayed the same doesn't mean the extension wiring is OK. It means that the extension wiring is carrying the ADSL signal and isn't immediately messing your sync up. If the extension wiring isn't balanced (twisted pairs) then it could still be compromising the interference immunity of the system but if there is no interference right now you will probably sync OK. The problem is likely to happen when a source of interference is present (like cars/motorcycles driving past, your neighbour using his petrol lawn mower or your central heating kicking in and out.)
The 135k profile is what is stopping you going fast. However you need to take into account why the profile has gone down. The profile is the symptom of the problem, not the problem itself. Some source of electrical interference has come near your phone line (e.g. a faulty electric motor, a badly suppressed petrol engine ignition or a radio transmitter/medium wave broadcast signal) Your line failed to reject this interference (likely down to the extension cable and filters) and this has caused your modem to lose sync and disconnect from the Internet.
This interference and disconnections obviously happened a large number (10s) of times and the exchange has decided that there is a problem with your line. It turned your speed down and raised your target SNRM to try and keep the line working. This didn't help so it did it again... and again... until you ended up at the lowest speed possible. You can get the profile reset but unless you fix the problem that is letting the interference in then it's almost certainly only a matter of time before it happens again.
The sync/profile tells us that the quality of your line is probably OK (your sync is respectable and is higher than mine) but you're probably suffering from bursts of interference. The problem is likely that there is some source of electrical or radio interference that comes into your environment quite frequently, that your installation is failing to keep it out and that when it happens it causes your router to totally lose connection. I notice that your old profile was lower than the sync value would suggest. This tells me that it is likely your system has trouble holding full sync at night when radio interference is the strongest. Another indicator that you may have a wiring issue.
Even if your router is connected to the master socket, if you haven't removed the bottom half of the socket and disconnected your extensions then the extension wiring is still connected to the line and will be functioning as an aerial, picking up stray signals and interference and funnelling them straight back into your master socket.
I stand by my advice given earlier.
Cheers,
Paul.

I second that Paul.
Have a :karmic: for a clear, if not concise, nevertheless excellent explanation. :thumb:
I speak from experience having "been in BT's jail" with an IP Profile of 135 Kpbs myself. ;)
As already mentioned by others I was let out after 3 days but with no time off for good behaviour. :)
An improvement tonight in my connection speed.
speedtester.bt.com reports @ 00:45am (monday morning):
IP profile for your line is - 4500 kbps
DSL connection rate: 832 kbps(UP-STREAM) 5664 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 4175 kbps
result :thumb:
That's the correct profile for your sync speed, Gyruss, but the latter had dropped since you first reported it, which suggests an instability with your line. Have you tried the test socket yet?
Looking better, but as Rik says, it looks like the noise is quite variable. You should definitely give the test socket a go! :)
Found this page particularly useful in terms of describing IP Profile: http://www.thinkbroadband.com/faq/sections/radsl.html#connection
I will ofc check the 'test' socket that sits behind the faceplate of my bt master socket as a test, but before i do any further disconnection of any of my equipment now, can i just check with you guys..
Is it best practice to switch off the router whenever a disconnection of the telecom socket from the master is done? (eg, to switch the connection to the test socket). I read on a site that switching off the router in most cases creates a 'last gasp' signal which won't be interpretted by BT as a fault with the line? Is this correct? If so i'll just be doubly sure I do switch off the router first. (admittedly i haven't been switching off my router 60% of the time), with my frustration trying like heck to get my connection up from 5700 downstream to see if i can improve it.. i may have omitted these basic safeguards.
I'm guessing its these disconnects that had lowered my profile in the end.
If on the test socket however i get no improvements etc, do you think that the downstream will ever be more than this 5700 or so? Previous house was further away from the exchange and got pretty much the full 8000(ish) downsteam, where i am now 1.6km from it, and only get at best this 5700(ish) figure.
Despite my knowledge with computers and the internet though, i really did learn ALOT this weekend, so thanks very much chaps for spending the time with your excellent replies. I appreciated all of it.
Thankfully also found a nice site on the internet which details some nice 'hidden' config pages for my linksys router which gives me some extra facts n figures which before i relied on my netgear router for.
My linksys is a WAG54GS, and in their infinite wisdom they hid all the nice reports regard attenuation/noise etc away. but not anymore :)
Hi Gyruss
Generally, if you power the router off before disconnecting, the modem sends a last gasp signal, so the DSLAM doesn't "worry" that there's instability. The magic number, though, is 10. If the line sees 10 or more disconnections in an hour, it will react, so spread your experimentation.
Although we mainly look at signal attenuation (because it can be measured), there's a hidden and unquantifiable 'line quality' element which also affects your speed. This is affected by whether the cable is thick or thin copper, or aluminium, whether it's overhead or underground, whether there's a lot or a few joints on it, and it's basic condition. The only way we ever find out this 'effect' is to judge a connection at the test socket, which removes all your internal wiring from the equation.
:iagree:
I would expect that you will get better results at the test socket.
As Rik says, there is almost an unknown quality element, and this must be considered as well as attenuation alone. But, I'd say it should be possible to get full sync, and I suspect noisy internal wiring is what is stopping you. Hopefully, we'll soon find out. :)

My line is the exception, I get a worse connection through the test socket ???
It has been stable arong the 3mb mark since the BT eng found the fault last month.
How weird - did the BT guy say why?
He didn't have an answer Rik
Shame, that's a story I would like to have heard. :)
Hi,
Since ADSL is really a radio signal it may be that your line was an odd multiple of a half wavelength at some frequency it uses. Adding the extensions may have changed the length of the line just enough that a tone that was being lost then became usable.
Just a guess... Could also have changed the capacitance or inductance of the circuit.
Cheers,
Paul.
edit: typos galore!
Good theory, Paul, it works for me.
I suspect that the BT guy didn't know the reason. :eek4:
Me too

Chaps, as i'm on baby sitting duty tonight as the missus is working monday/tuesdays til 8pm, i'll probably test the main bt socket via the test socket on wednesday. Sorry for delaying this test, but my best attempts at being quiet resemble someone setting fireworks off at the local library :)
Will definitely test it though, see what you can make of the above info for now tho? Seems very thorough that report command, wish they would build that into the GUI of the router to export to a file perhaps.

Current Rate: 4416 kbs 448 kbs
Max Rate: 4416 kbs 1048 kbs
Current Noise Margin: 11.0 dB 25.0 dB
Current Attenuation: 41.2 dB 27.0 dB
Current Output Power: 19.4 dBm 11.9 dBm
and at 11 dB mine is high now but will be 6 dB by 11 PM-ish!
That said at the time you read it your Rate was considerably better than mine but mine varies very little as long at I leave it permanently on and don't reconnect when the Noise Margin is low.
I suffered the 135 kbps IP Profile for exactly the same reason as you - experimenting to freely with my cables at the inner BT test socket etc. but you only do it once! ;D
From my experiments the results were not that conclusive because time of day is a big influence on my connection as I found out and have mentioned already.
I now have an ADSLNation filtered faceplate on my BT Master Socket with about a 10 metre run of CAT5 cable directly off the unfiltered ADSL IDC terminals on the back of this faceplate. This CAT5 cable has 8 conductors in it arranged as 4 twisted pairs with a different degree of twist on each of the pairs to further reduce cross-talk between them. This is not a concern for me as I have have nothing else carried in the other three twisted pairs. Only one pair is used and this is dedicated to my ADSL signal. All the rest of my aging telephone extension wiring runs on pretty much the old existing wiring of various descriptions depending on as and when I installed it over the years, from the filtered IDC terminals at the back of my ADSLNation faceplate. There are no junctions/connections/joins in my twisted pair. The end at the router is terminated with an RJ11 plug that goes straight into the router.
This is the best I can do in my home without major civil work. :no:
I do believe that my bit is a good as it gets now so the remaining issues are with the line between me and the exchange and possibly in the exchange itself. Till BT upgrade the equipment in my locale I have to be satisfied with what I get but there may still be some things that you could do! :)
Saw an NTE5 faceplate filter suggested at: http://www.broadbandzone.co.uk/shop/centralisedfilter.html
Seriously considering this, and i may well invest in some cat5 on a reel soonish, or ask the friendly neighbourhood network engineer at work to loose some off his reel if he has some :)
Now you mention variable twisting done? ok humour me, are you talking about basically taking two wires from inside the cat 5 and varying the frequency of twists done? (oh go on!, i can hear you all laughing from here!! :) ) Differing the twists on each of the pairs? have i got that right?
(http://www.maplin.co.uk/images/300/vb20w.jpg)
Ok.. next question.. the RJ11's.. i luckily have a maplin virtually on my doorstep open 7 days a week, do you think they'd supply the RJ11 connectors i require? and if so i'm presuming i'd need the crimps too?
Anyway, i will definitely test in the NTE5 test socket on wednesday.. but as a pet project perhaps over the coming month or two (money permitting.. curse the forever increasing cost of living/working) i'll look towards far superior cabling like this.

I have had a quick look at the one at the end of your link and I could not see any mention of rear ADSL connections. If you are happy to plug the ADSL wire to your router into the the socket on the front OK.
I ran my CAT5 cable up inside my wall under the floor down inside another wall and out through a grommet to keep it out of sight so I went for one with rear ADSL IDC connections. This is the one I bought:

Yes you have it the pitch of the twist is different between the pairs. I was surprised by this myself when my length fell of the real of a network man I know and he mentioned this to me. He took the trouble to strip a short length of the outer sleeve to show me!

My supply of RJ11 and RJ45 plugs along with my crimp tool came from an eBay seller. Mine is not and expensive tool but works fine. On the basis that I only make up a few leads I don't need an industrial quality one if you see what I mean.

Assuming that the test socket improves your sync, and you decide to fit a filtered faceplate, there's little point in improving your internal wiring. The beauty of a filtered faceplate is that it filters the ADSL as the line enters the house, so the internal wiring is out of the equation; at the same time, the extension wiring is pre-filtered for voice (hence no microfilters are required).
Alternatively, if it's not feasible to site the router at the master socket, a filtered faceplate is not really any good. Instead, then it would be a good idea to improve internal wiring, e.g. using cat5 cable, removing the ring wire, etc.

On a side note, does anyone think a 2wire router would improve my DL sync? Am on a TPON with copper overlay (and maybe some string with yoghurt pots each end :()
I used to get 1024 sync but with constant drops, at least it's stable(ish) at the moment. SNR is always at 11db when I've checked it.

I haveto take issue with this Sebby.
As I said before I run an independent CAT5 from the ADSL IDC connectors supplied for this purpose at the rear of my ADSL filter faceplate for the very reason that my router cannot be easily located adjacent to ther Master Socket.
Mytheroo your attenuation suggest that you are a long way from your exchange. A 2Wire may help and at the price some go for on eBay why not give it a go? :)
I should re-phrase what I said. "Not very good" is not what I meant. I meant that it might be more simple to remove the ring wire, etc. You can run a cat5 cable from the filtered faceplate, be it from the front or rear, or you could potentially achieve the same thing by improving internal wiring. :)
Idnet emailed me at work today and have asked if i can connect my router up to the test socket while they run some tests. I'm going to leave it pretty much connected to the test socket all day tomorrow, so when i logout tonight going to plug the router direct to the test for them to test whenever and however often they wish to during the day.
For the hell of it anyway and due to a nagging curiousity anyway, i plugged the router into the test socket once i got home from work (earlier on)...
here is the stats page from the linksys router while connected to the test socket... ahh well.

Well the sync is an improvement, especially given that the router has connected at night when there is more noise around. You'd probably get 6Mb or over in the day at the test socket.
But, the actual level of sync is not really the issue; it's what is causing the disconnects and variability in sync, which is no doubt noise.
Let us know what IDNet say. :)

This looks much as you posted back post at Reply 38 the SNR is slightly lower at 14 8 dB instead of 15.3 dB.
All that I can think of is that at some time or times of the day the noise increases in some sort of burst that causes your line to disconnect. Tracking down and eliminating the noise is one possibility but may not prove easy to do. Another is to take some measure to improve the noise immunity of your line maybe with the use of twisted pairs to carry your ADSL signal. Do you use good quality ADSL filters? These devices are know to vary in performance considerably. There are sure to be more ideas forthcoming from those better able to provide them than me but that's my penny worth for starters. ;)
Maybe using routerstats would help identify if there is currently undetected noise bursts?
James from IDNET sent me a mail, saying:
"Thorough testing of the line suggests that the connection is stable and noise level on the line are as they should be. The IP profile is also at a good setting, this indicates that the stability of the line is fine."
Connection speed at time of test was 5888k.
Got a few fairly quick questions if anyone can answer them.
Q1:
In the Linksys router the DSL Modulation is set to Multimode. Choices in its drop down are (Multimode, T1 413, G.Dmt, G lite, ADSL2 and ADSL2+), is multimode the correct choice? The settings i was provided for the setup of my router by idnet didn't specify this modulation , so thought i'd best ask.
Q2: MTU size. Currently my router is set to 1500. Is this the recommended setting for IDNET connections? or should it be one of those lower settings around 1458 etc.
A1) I'm guessing that Multimode is another way of saying automatic! If you really want to choose one of the others you need G.Dmt.
A2) This one isn't so easy to answer, as such. Definitely leave the router 'wide open' at 1500, but make any desired changes in Windows. I use 1500 as do some others, but then some people have gound 1458 to give better results. The best way of deciding is using TCP Optimiser to find it for you! Have a read of our FAQ here. (http://www.idnetters.co.uk/forums/index.php/topic,1904.msg31673.html#msg31673)
Hope this helps!
As Lanced says, however if using vista MTU is supposed to be set intelligently and also a tcp optimizer is said not to be required.It has set mine at 1500 believe it or not ;D
I also agree. Leave the router set to 1500 and make the change on Windows once you've found the optimal value.
With my router connected direct to the test socket it shown no sync connection improvement (not the ip profile), there was 'minor' improvement by changing the cable between the router and the socket to a fully shielded twisted pair version of the same (high speed broadband version)
My house is 1.34km from the exchange as the crow flies, and 1.6km by roads.
as the noise level was commented on a few times due to it being 14.8db - 15.2db, and this didn't change even from the bt test socket, and even with the twisted pair cable in place..
will a filtered faceplate such as that from ADSLnation even improve things? If you think it definitely will, i'll order on tonight when i get home.
The ADSLNation faceplate is made from premium filters. I can't guarantee an improvement but it certainly won't make it any worse :)
Your noise level is important the system changes settings to get this value to a "target value". In your case this target is 15dB. This is the highest the target can be (lower is better) so 15 isn't good. It says that your line was unstable at lower values. The system sets this value at the lowest one that keeps your line up and stable. The possible values are 6,9,12 or 15dB and the lower the value the faster your line will go as the weakest tones get dropped until the target level is achieved so the higher the level, the more tones get dropped and the less speed you get. The measured value is a result of this process not an absolute.
The noise target gets adjusted downwards very slowly (not every time the modem is powered on.) Once your profile has maxed out if it stays stable for 2 weeks the the noise level will get reduced by 3dB. This will usually cause a speed increase, then the profile catches up and if the line is still stable the process repeats every 2 weeks until the lowest stable value is found. If you get huge numbers of disconnections then the target value can rise very fast.
Your line is at 15dB (3 steps up) so if it was to finally stabilise at 6dB it could take over 6 weeks for you to hit your maximum speed. I can't comment on how mush speed increase you might get if you went all the way down from 15 to 6 but I'm sure someone can make an informed comment.
Cheers,
Paul.
The problem is that your target SNRM has been raised to 15dB to stabilise the line, so nothing is going to make this figure drop in order for you to sync higher apart from 14 days without losing sync.
If the test socket showed no improvement in the sync @ 15dB, your wiring must be okay. That said, a filtered faceplate may make you less susceptible to noise surges - perhaps this is what has caused instability in the past.

The possible values are 6,9,12 or 15dB
Mine is 11dB. How come?
Your target is probably 12 and the final value it settled on whilst trying to hit the target was 11 :) You can't see what the target is, only what the actual value is right now.
Cheers,
Paul.
That probably means you have a 12db target and are dropping a bit or a 9db target and are re-syncing at night, so figures during the day are better, Ann. The only way to find your target is to check immediately after a re-sync (or ask support).
Or what Paul said...
Thanks guys. What Paul said makes sense. It used to be 15 and now it's 12 but actually doing 11 or sometimes 10. Shame it won't go down to 9 or I reckon I'd get full synch again.
Hi,
Sounds like it's going in the right direction...
Since it oly sounds like you need a couple of dB if you don't already have them you could try fitting an XTE2005 filtered faceplate and a pro modem cable and, you never know, in less than a month you may get full sync again :)
Cheers,
Paul.

It the target has moved from 15 to 12dB, there's no reason it won't drop further (unless your line can't hold sync for 14 days at 12dB, in which case you're stuck there).
It doesn't work like that for me. The line holds synch for ever but there must be something wrong with it. I've already done the filtered faceplate and good cable and I don't have any extensions or Sky and there's never been a ring wire in sight so I can't do any more. I've got a synch speed of 7616 which I ought to be happy with but you know what it's like.. just want perfection.. ;D
Off to Silverstone tomorrow and supposed to be ironing and packing.. :whistle:
It sounds like you have interleaving on, Ann.
I do Rik, but I've still had better in the distant past with interleaving on. Anyway it doesn't bother me until I read here and then I get niggled by it. ;)
Imagine how I feel. ;)
Wave as you go by on your way to Silverstone. :)
In that case, Ann, you're stuck as BT will have to adjust the target manually. It might be worth having a word with IDNet as they may be able to help.
I think 8,096k is possible with interleaving on.
Just an update ...
Finally but the ADSLNation XTE-2005 Master Faceplate and a 15m run of RJ-11 Twisted Pair (Pro+ ADSL 2+ certified) from same company.
Done a 'speedtest' @ bt and while my current ip profile is low due to the issues i have been having, i'm going to see if this new faceplate and cabling helps at all. Should be about 5 days I expect, but 7200 is at least encouraging for now as a connection rate.
Your DSL connection rate: 7200 kbps(DOWN-STREAM), 832 kbps(UP-STREAM)
IP profile for your line is - 3500 kbps
Actual IP throughput achieved during the test was - 3228 kbps
Strangely, my previous 'soap-on-a-rope' filters were all quite problematic in that even when having phone and the adsl cable connected through it, was still getting drops of the internet whenever voice-calls were present on the line. Had 3 filters and yet all 3 seemed to sync at really low speed whenever i would put both the extention cable and the phone in then plug the filter into the master socket. Actually makes you wonder if the phone is an issue at all :)
On another note: got this from the plusnet site:

Wholesale Broadband Connect (WBC) is BT's next generation broadband product for ISPs. BT are currently upgrading each exchange to be able to offer WBC which will also bring ADSL2+ speeds of up to 24Mbps. We will post updates to the upgrade schedule as and when we receive them and also provide further details on WBC in the coming weeks.
WBC Rollout Status
BT have announced a ready for service date for this exchange. The estimated go live date of 31st March 2009 and was last updated 20th August 2008.
Sounds like the extension was picking up noise which got past the filter somehow. Hopefully, you'll now see your profile rise to 6000k, with throughput to match.
And of course the check for SNR... from 14.8 => down to 11.8. BONUS!!!!!!!!! :blush:

So all that now done, the cabling fully channelled.. AM Radio test DONE (as per another post i saw you guys reply to), i'm confident certainly from my side at least that i've done as much as I can do for now :)
So thanks very much for your time, patience and inspiration to tame this darn internet connection I have.
I work in desktop support as my day job, and its been an absolute pleasure to think-tank this problem out with you guys. In your own way, you guys make a big difference, and while not being employed by IDNET, I am pretty sure your efforts go a long way to not only keeping them customers, but also winning them custom too.
Top job guys :) I'll certainly try to help out on these forums in between bouts of MMO gaming :)
Thanks, Gyruss, we try to fill in the gaps where we can. :)
I'm really glad to hear of your success. :thumb:

Thats a hell of a lot better than I had before. :)
No more flat extention cable exists, its now twisted pair RJ11 (adslnation pro+), the ADSLnation filtered faceplate was simplicity itself to fit, and I no longer have those soap on a rope filters at all.. couple all that with the reduction in noise, it worked out. Would have done this sooner but with a baby around, spare money isn't at a premium :)
again, thanks alot.. now that my IP profile is back up I am happy :)
That's pretty much spot on now, Gyruss. Good news. :thumb:
Great result. :thumb:
Necro'ing my own topic as the problem i'm having is ongoing...
Sent an email to Idnet support over the weekend and Brian responded today asking me to do a BT Speedtest and reply with the results, figured as i'd ran this test i'd post here too.
Anyway i've also called BT out because once again i can hear 'noise' on voicecalls, and also had many disconnections both during normal operation and when voicecalls are made. (yes have changed and checked various filters)
3 routers tried, recabled with ADSLnation Pro+ cabling twice (2 sets of cable), 2 * ADSLnation faceplates tried, new phone purchased, tried ferrite rings too just in case... nothing has stabilised it with my best efforts.
I noticed on the test i did in the test socket that the range was saying up to 21000kbps? weird, hadn't ordered that upgrade.. so predicting its the speedtest from BT up the wall?

Upload speed achieved during the test was - 522 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 928 Kbps
Is difficult to know what's going on , hopefully BT will have a solution
i have asked them to also check for a HR leg fault this time too.. seen more than a few posts dotted around the internet now with similar symptoms to mine and the hr leg fault was suggested on all of them.
The following is a short capture of my noise margin that routerstats lite is seeing this afternoon. The red is when I powered down the router to try my other router also.

Sorry forgot to add yesterday.
I don't want to seem like i'm just moaning on here about the woes' of my internet connection, i appreciate any and all the help i can get in truth, its one of those wits end scenarios where you feel you've tried everything you can think of and are caught between the ISP and BT with what seems like not much else I can do. So I've always appreciated the responses i get, but i'm sure even you chaps are now as stumped as I.
This HR Leg fault i've seen suggested on some broadband forums and the more i see folk posting about similar problems to mine, the more i'm convinced it may be the cause of all my issues with the constant resyncs and resultant lowered profile.

You know my story about recabling and multiple routers tested etc etc.. but in essence i can hear noise on the phone line whenever my router is connected and sometimes a caller is inaudible due to the radio-like hiss whenever the router is on.
17070 tests do not always make the crackly/hiss noise when only phone is connected to the test socket, it kind of comes n goes
Was on the internet the other night and a cold caller rang at about 8pm(ish) and my connection instantly dropped. (grrr like i need another reason to despise cold calls)
All this despite recabling, router changes, faceplate changes and the like
anyway, i've called BT out again for this whole thing, I expect they will need a hawk tester and do the full test with the device at other end of the pair too?
When I had the problem of BB dropping if the phone rang, I had to get an engineer out, he re-crimped a few joints, which solved the problem for a couple of years. Until in Jan this year, I was connecting between 100 - 250kbs, BT came out again, this time, the cable through my garden was replaced. I now sync at 3168, with a 2500 profile, something I haven't seen in 3 years.
Got a Netgear DS108 Dual Speed Hub today from a friend in work. I've a suitable length of CAT5e
My current set up at home is:
In hall @ front of house by front door:
Master Socket with ADSLnation filtered fp => Twisted Pair 15m RJ11/RJ11 Pro+ Cable to Router and Telephone plugged into other socket on filtered faceplate.
Upstairs @ rear of house:
Cable connects to my DG834gV5 adsl router, and into that is plugged two pc's belong to me and my other half.
So with the hub, i'd be hoping to connect the adsl router itself in the hallway with a 1m RJ11 lead to master socket then run from there using the Cat5 cable to the Netgear HUB upstairs where both pc's will then be also connected to it.
Can you see a problem with this thinking? or is the logic fairly sound?
It makes a lot of sense to keep the length of cable between the master socket and adslrouter to the shortest possible, I hope it improves things.
you see me having any issues connecting fro the DG834g (4-port) to the DS108 hub? reckon it will just work? or will i need to put in manual ip's?
It should really be 'invisible' with the PCs picking the IP address from the DHCP server on the Netgear DG834 as before.
thanks. I'll likely do this at the weekend now, want to see what the BT chap says first, and will move my router around then.
I've connected the router in the hall on a shelf near the front door now, cat5 cable run up the stairs and into the rear 'computer room' aka 'the den'.
In there now is the Netgear Hub and the 2 pc's connected to that.
DHCP.. worked fine, and the internet comms also working. 7128kbps upstream 928kbps downstream profile: 1468kbps (approx)
Naturally i need to now leave it connected like this for the line to retrain the adsl..
So testing that config using routerstats today so it will register any drops if they occur.
How do i find out if my connection is 'banded' btw? as i've now moved my router, entirely could do with a 'clean slate' scenario to now test it with.
I'm not sure, Jase, Steve or Lance may know.
I believe the bandings to be as follows:
(http://community.plus.net/library/wp-content/uploads/2009/09/banded1.jpg)
If you are syncing at or near the top of the band, and have a high downstream noise margin, its likely your line has been banded.
I forgot to add, support may be able to get the banding removed.
Doesn't look like banding at the moment, your profile is well below your sync,thus giving you poor performance, if you can maintain sync it will rise.
Well.. i was actually going to cancel the BT visit to give me time to test, but my other half is off work today and when she made a phone call to a friend, noticed that the internet had dropped .
XTE2005 adslnation faceplate in place, into that is only 2 cables (with no extension wiring) 1 is the router (half a meter cable away) and the other is the phone itself. (brand new and i've tested that phone next door on his broadband, it does not drop his broadband)
This faceplate is also the 2nd of the same make/model as i bought a 2nd one to try to eliminate it being the cause.
So i'm off tomorrow and will hopefully get some peace if BT can fix this. I suspect i 'may' still have this 'HR Leg fault' http://www.digitalspy.co.uk/forums/showthread.php?t=949974 as all the symptoms i've witnessed on my connection are eerily similar/same as those in that digitalspy forum thread (linked)
Well, since the BT visit and at the weekend which stayed around the 1.4mbps my line increased last night to around 3300,
but today.. now.. getting this:
(http://www.mybroadbandspeed.co.uk/results/53468331.png) (http://www.mybroadbandspeed.co.uk)
a sign of stability on my line at last? especially when you consider it was nosediving for ages.. well it has aint it?
I'lll see if its stays this way now.. for the next step is an SFI visit.. but i am very happy with these kind of speeds considering :
a) where i live
b) what i was used to 1 street away.
:fingers:
Indeed :)
Router Seems to be really quite stable around these values too:
ADSL Link
Connection Speed
Line Attenuation
Noise Margin | Downstream
7392 kbps
38.0 db
8.5 db | Upstream
896 kbps

(p.s. i'm liking the table function on this forum, seems to be some nice plugins)

You're the first one I know who's worked out how it works, including me! ;D
You can see from the code block below that i only use the column function but it worked for what i needed, handy if you are laying out information, and i'm sure you could write an excel macro to inject the forum tags if you needed do anyway, so you could virtually export tables from excel if you wanted.

Umm... I don't think I could, Jase. :red:
ok stop it now, you're making me feel like a geek ;)

Finally managed to do a BT speedtest on my Window 7 pc, ended up having to use the 32 bit version of IE8 though:
Download speedachieved during the test was - 6296 Kbps
For your connection, the acceptable range of speedsis 2000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :7392 Kbps(DOWN-STREAM), 896 Kbps(UP-STREAM)
IP Profile for your line is - 7131 Kbps
Upload speed achieved during the test was - 727 Kbps
Additional Information:
Upstream Rate IP profile on your line is - 896 Kbps
That speed's still a bit slow for the profile.
Well speed tonight is pretty lousy, had been fine all day, and bt speed tester is not up.
(http://www.speedtest.net/result/984472295.png) (http://www.speedtest.net)
I'm hoping its just congestion, but with the past history of profile issues i've had, its enough to make me go 'oh no :('
Same'ish speed as last night this morning too.. all this started with those bt wholesale messages on friday night.
