Title: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 04, 2010, 11:55:33
Hi, I have a Netgear DG834G V2 with firmware V3.01.38 installed for my Idnet ADSL2+ connection. Since i switched to ADSL2+ I have lost about 500kbps download speed and was wondering if there was any way that i could speed things up a little as downloading large files is painful. I am considering buying a new router but would like to run it past you guys first to see if its worth my while.

Here are my stats atm...
ADSL Link                  Downstream      Upstream
Connection Speed    1149 kbps      821 kbps
Line Attenuation            52 db      17 db
Noise Margin            9 db              6 db

Any advice is appreciated.

Cheers

Hi Jup

I have a 2-Wire 2700 and achieve a sync of 4229 on a 62db line, albeit with a 6db margin, worth about 500-700k of sync speed. IOW, for target margin it would only be 3500 sync. As that's still 3x what you're achieving, I would say it's well worth trying (<£20 on eBay). The v2 is very long in the tooth now.

For some people, due to the condition of their line, ADSL2+ will actually be slower that ADSL (Max). If that proves to be the case for you after a change of router, ask IDNet to have you remodulated to ADSL - it uses lower frequencies than 2+ and is, therefore, less prone to interference (and should give a lower attenuation).

Hey Rik,

Thanks for the reply, I'll try a 2-wire 2700 and see how that goes, can't go wrong for £20 quid. I'll post back with results when I get the router. By the way is it easy enough to install/set up?

Cheers

Very. Try for v5 firmware if you can, but otherwise the 2700 board has all the instructions you need.

Thanks again Rik,

I have picked one up for £18 delivered, should be a few days before it arrives. The guides on the 2700 board seem straight forward enough....even for me :fingers: I'll post my results for any that are intrested.

Hi again,

The 2700 router just arrived. I have a quick question before I start. Do i need to use the 2-wire filter and cables that came with the router or am I ok using my own? I have adsl nation filters. Also there is no software disc which should have, will this be a problem?

Cheers

Post by: Glenn on Nov 06, 2010, 14:28:58
jup,

Your own filters should be fine, don't use the  cd to configure the router, just follow the guide here (http://www.idnetters.co.uk/forums/index.php?topic=8927.0)

I have a small problem when i get to (4. When the page opens, click on Run System Setup Wizard in the box at the bottom right hand corner of
   the page.) I can't seem to find any setup wizard function anywhere. Anyone can tell me where i can find it?

I never used it, tbh. I did the setup manually - that may refer to an app on the CD, and I hate router CDs. ;D

Thanks for the replies guys,

Still not able to get it connecting properly, problem seems to be that it won't let me change the current password that is set and it will not let me save my connection details. I can however see my line stats which are slightly lower than I have at the moment, wish I could find the setup wizard tbh. Will have another crack after I have been fed and watered ;D

Hi Rik,

I don't see a submit button only a save button. The router page layout is different from the the one in the guides, here is a pic. I tried using both the javascript option and the save button.

Jup, the bold part is what you are missing

After editing the Broadband Link Advanced Settings page including your ADSL/PPP username and password, do NOT press the red 'Save' button displayed on this page otherwise you will encounter the 'PPP username invalid' error message.  To save you newly edited settings, simply type, or copy & paste the following javascript command into your web browser and press the Enter/Return key.   This command bypasses the checking that takes place when you normally press the 'Save' button.


                  javascript:document.pagepost.submit()

Hi again,

I have tried again to get the router to connect, I followed the instructions in Glenns post but my user name/password will not save. When i entered the javascript command it at first prompted me to enter password and submit, which I did but it still did not save. The next few attempts it did not prompt for router password the page just seemed to refresh after the javascript was entered but my details would not save.

I'm puzzled tbh (not hard mind) any other advice would be appreciated:)

You have the V6 firmware  go to the  PPP Login page (http://192.168.1.254/xslt?PAGE=HURL13) and enter your full Idnet username and password and then the router's own password.

You will get a  Configuration Successful message and that's it, your done.

If it fails, then just repeat it again.

Remember to set up firewall, wireless security etc.  Turn off Fusion and Openzone on the home page.

Hi guys,

Quick update, I have managed to get my details to save ;D What happens now is that when I try to connect at PPP Login page I get PPP error username not recognised. I have tried this 5 times but still no luck. Do I just keep trying until I connect or have I missed something? Again I appreciate your help :)

Cheers

Post by: kinmel on Nov 09, 2010, 14:32:47
My first thought is to double check that you are entering the correct data for the PPP and also the correct router password. :dunno:

There is nothing else that needs doing from the PPP login page, so repeating more then once isn't the answer

PS do you have a stale PPP session ?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 09, 2010, 15:04:45
Hi Kinmel,

Thanks for the quick reply, PPP Login I just use the smae info I use to log into my idnet account, so am pretty sure that is ok. How do I know if I have a stale PPP session?

Do you have an NTE5 master socket, the type with the removable bottom part of the faceplate? If so, try the router there, plugged into the test socket which is revealed after removal of the faceplate. That will cut off any extensions and internal wiring you have.

That would certainly seem to imply that your internal wiring or connected devices are causing an issue. How many sockets do you have, what's connected to them?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 09, 2010, 16:23:19
Hi Rik,

I have 4 sockets in the house. 1 Upstairs which does not get used. 1 Test/main socket in hallway with phone connected. 2 in main living room, 1 beside tv with sky plugged in and the other next to my pc with broadband connected.

Is there a connection to terminal 3 on the back of the faceplate for the master socket, Jup?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 09, 2010, 16:48:12
Nope nothing in terminal 3 just 1 wire in each terminal 2 and 5.

Cheers
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 09, 2010, 16:50:32
Then disconnect all other devices from sockets, put the faceplate back on and check the stats when connected to the master socket, Jup. If that still shows the extra speed, it would suggest a device is noisy. The Sky box would be my first suspicion.

Yep, I would go with trying ADSL1 as Rik suggested earlier. With that attenuation you're not going to get much benefit from ADSL2+ ( in fact the 2700 is only synching at ADSL2 ). A Bit Loading graph might be useful to see, but I'm not sure how you get that on a v6. I'm sure Alan will post the link for you.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 09, 2010, 17:42:09
As MisterW says, Jup, you're not getting much benefit from 2+, unless you are making use of the higher upload speed. ADSL Max should lower attenuation, so you stand a greater chance of better d/l speed.

One thing that bothers me still, my download rate has gone up about 400-500kbs which I am happy about but when I download a file or do a speed test my speed seems to be exactly the same around 88-90kbs as it was before. Any ideas why it has stayed the same.

Something not quite right there, why is the upstream only 288? , should be 448 even on ADSL1.
That looks like a fixed rate 1Mb connection to me...

Thanks for the quick replies guys,

Here is the speed test result..

Download speedachieved during the test was - 649 Kbps
For your connection, the acceptable range of speedsis 400-1000 Kbps.
IP Profile for your line is - 750 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 13.36:20.94:65.7 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

Can i get off the fixed rate if the line is indeed fixed?

OK, you've been remodulated to ADSL Max, but then capped at 1M in order to stabilise your line. Give it a week and see if things remain stable. If they do, call support and they'll lift the cap and see if you can retain stability.

Looks like its been moved from a fixed 1Mb to a normal ADSL1 connection since the upstream's now back at 448.
The target noise margin has gone up though, which would tend to indicate a 'banded profile'. Only problem is I didn't think they were used on ADSL1 and also there isn't a profile with a maximum synch of 768k, very odd...

Have a word with support, see if they can reset the target noise margin for you.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 19, 2010, 12:34:34
Hi Rik,

I called support and they reset the target noise margin for me no problem. I'll post back once I start seeing some changes. Thanks again for the help, much appreciated :)

Cheers
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 19, 2010, 12:35:33
NP. Good luck with the change. Did they tell you when (if) you need to reboot the router?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 19, 2010, 14:24:44
Hi Rik,

No they never mentioned rebooting the router, just said that i'd see some change in about 4 hours. Should I reboot do you think?

Cheers
Title: Re: Setting up a 2700 for ADSL2+
Post by: Steve on Nov 19, 2010, 14:45:39
I think I'd leave it as is, you can keep an eye on the margin yourself,the reset should force a resync.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 19, 2010, 15:23:52
If the router hasn't resynced then yes.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 19, 2010, 17:07:59
I have waited 5 hours and still no change, so I rebooted the router but still joy, infact the noise margin crept up 1dB. Have i jumped the gun here or has the noise margin reset just not kicked in yet?

Cheers
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 19, 2010, 17:08:58
What exactly did support say?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 19, 2010, 17:16:53
Hi Rik,

They said that they had now reset the noise margin but it would take 4 hours for it to start working, they also told me that i'd have to leave my router switched on but I took that to mean that it would have to be left on overnight. Nothing was said about a reboot, hope i have not screwed up here :(. He also commented that my router had been stable and said that they could only reset it once every 10 days. Pretty sure thats all that was said.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 19, 2010, 17:19:13
I've just spoken to support, they've seen multiple resyncs. If that wasn't you doing it manually, then your line is unstable and has re-targetted back to 15db.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 19, 2010, 17:22:33
I rebooted only 1 time. Is it worth me trying my Netgear router again, the noise margin was never that high with it?

Cheers
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 19, 2010, 17:24:10
It's worth a try, but give it an hour, or wait till the morning, so that the exchange doesn't see it as more signs of instability.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 19, 2010, 17:26:21
Ok i'll leave it until late tonight or tomorrow morning. Will let you know how it goes :)

Hi again,

I checked my connection this morning and my profile has dropped to 500kbs again so I swapped back to my netgear router. Noise margin dropped 4dB and my download rate went up. I take it I will have to wait for the line to sort it's self out again and see if the profile rises again. I think that the 2700 does not really like my remodulated line. Will post back when I see some changes.

Cheers

Post by: Rik on Nov 20, 2010, 10:52:09
Sadly, you will. Netgears seem to be more compatible with MSANs than any other brand, though my 2700 gets on fine with the MSAN.
Title: Re: Setting up a 2700 for ADSL2+
Post by: shpub on Nov 22, 2010, 10:01:44
This looks very similar to my experience with the 2700.

See http://www.idnetters.co.uk/forums/index.php?topic=22013.0;all

It does seem that the 2700 performance is very much line dependent. In the end I tried a Billion 7300 which works very well

I had to go through several resets as Speedtester was getting really confused though.

However, I have been connected now for 28 days at 1188...

Post by: Rik on Nov 22, 2010, 10:37:05
Like all routers, we've seen good and bad reports on the 2700. For some, me included, they're little short of miraculous, for others they do nothing, for some they have a negative impact. It demonstrates, rather worryingly, how variable the equipment we connect to at the exchange is. :(

Hey guys,

Quick update, its been a couple of days since i connected my netgear. Seems like the noise margin is getting better but still no movment on my download rate.
ADSL Link    Downstream    Upstream
Connection Speed    864 kbps    448 kbps
Line Attenuation    50 db    15.5 db
Noise Margin    10 db    19 db

Should I be seeing a better download rate by now or will it take longer for the line to sort it's self?

Cheers
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 22, 2010, 18:39:08
You won't see an increase in speed until the line resyncs. When it does, you need to take a look at those stats immediately and see what the d/s noise margin is, Jup.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 22, 2010, 18:40:45
Hi Rik,

Thanks for speedy reply, do I need to restart router to get a resync or will it resync its self if the line stays stable?

Cheers again:)
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 22, 2010, 18:43:07
You'll need to do it. Given the BT work overnight tonight, I'd suggest you think about powering down before midnight, then power up again after 6 tomorrow morning.

Hi again,

Did a resync switching router off last night and powering back up at 7am this morning when i got home from work..
ADSL Link    Downstream    Upstream
Connection Speed    768 kbps    448 kbps
Line Attenuation            51 db    15.5 db
Noise Margin            15 db    11 db

I just took my stats again just now...
ADSL Link    Downstream    Upstream
Connection Speed    768 kbps    448 kbps
Line Attenuation            51 db    15.5 db
Noise Margin            13 db    11 db

Noise margin coming down again. I am a bit puzzled as my profile used to be much higher than this before I switched to adsl+2. Anything else I can do or try to improve the down stream?

Cheers
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 23, 2010, 15:28:37
Ask IDNet to remodulate you to ADSL Max. Some lines just don't work well with 2+.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 23, 2010, 15:39:06
Hi Rik,

Did that last week mate. Think they would switch it back to adsl+2? For me as it was working better with it, here are my stats before i got remodulated..
ADSL Link                  Downstream      Upstream
Connection Speed    1149 kbps      821 kbps
Line Attenuation            52 db      17 db

Post by: Rik on Nov 23, 2010, 15:46:44
They will, but you need to find out why the line has become more noisy. Where's the router connected, master socket, hard-wired socket or 'flying lead' extension socket. What else is connected to the line, especially have you added anything new recently.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 23, 2010, 16:00:29
Router is plugged into the master socket, no extension used. I moved my phone away from router, in fact i put it upstairs well out of the way. I have had sky unconnected for over a week now. Honestly nothing ahs changed my end except for what i have just listed. In the whole house I have broadband connected downstairs and my phone connected upsatairs thats it.

Yeah all sockets have the ring wire removed mate.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 23, 2010, 16:40:55
That pretty much rules out self help, there's only one other thing I can think to check, apart from a filter swap. Open master and extension sockets and check you do have a twisted pair connection, eg the wires are blue/white & white/blue.
Title: Re: Setting up a 2700 for ADSL2+

Then you need to talk to support about your options, Jup. Please be aware that getting a BT engineer out can cost up to £195+VAT.

What make and model is the phone, btw?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 23, 2010, 17:15:11
The phone is a BT Graphite 1100 twin. Don't fancy shelling out £200+. Can't figure out how the connection and noise margin has dived since the remodulation from adsl+2 back to normal adsl.
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 23, 2010, 17:27:49
The Graphites have a very bad reputation for interfering with ADSL. Could you try an alternative?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Jup on Nov 23, 2010, 17:43:56
Yeah i could try another, would the Graphite cause noise even though I have it plugged in upstairs well away from the main socket?
Title: Re: Setting up a 2700 for ADSL2+
Post by: Rik on Nov 23, 2010, 17:45:40
It certainly can. There's quite a lot of discussion of it on Thinkbroadband.

Don't mean to sound stupid  :blush: But do you mean wait a couple of weeks before resync or resync then give it a couple of weeks for the line training to do its thing?

Think he means give it a couple of weeks before rebooting so the BT kit 'sees' a stable line.
