Anybody been regraded yet ??, not sure if I have...if I have it has not made any difference to download :( but upload...hmmm

Ok....I know why speed is low....my SNR has dropped from 26 to 5.5 :o
Nothing my end has changed since yesterday......so why the big drop ???
Yes! Synced at 6528kbps :)
Speedtest (http://www.adslguide.org.uk/tools/speedchart.asp?id=12d46b7a10a5ef008e145dd0f36) disappointing though :(
Just found this on Adslguide -:
http://aaisp.blogspot.com/2006/04/initial-rate-cap-on-max-lines.html
Apparently I am synced at 8128kbps :o
Ah OK but I`m not touching anything! I`m scared that I re-sync at 512! :D
;D
Yup,
ADSL Link Downstream Upstream
Connection Speed 8128 kbps 448 kbps
Line Attenuation 34 db 11.5 db
Noise Margin 7 db 21 db
Capped at 2mbit still just like everyone else I think! ;)

Longest 75 minutes I've ever known ;D
Synched @ around 4.45 this morning and still on 1930ish

It is BT we are talking about... ::)
I rebooted the router about an hour ago, and I'm getting 5.5mbit speeds :)
all right for some ;)
I've rebooted 2 or 3 times but no luck yet.
Haven't tried booting the cat yet but 'tis on the cards [grin]
Rebooted but no difference in throughput, however, synching at 6848 now :)

hehe yeah, though i must admit im not getting stable speeds..keeps going up and down....its been the same with 2mbit for the past 3/4 weeks :-\
There are going to be some bizarre speeds with Max. Ppl need to realise that sync speed and throughput can be entirely different ;)

yeah no doubt, but i've been having the same with 2mbit recently (speeds down to 70-80kbps)..could it be down to contention?
Yes, most definately exchange contention. I`ve been suffering it for months :(
Well, rebooted and now synching at 7008kbps! Downloading at 750kb/sec atm ... sweet :)
>:( so it will be another month or so, before BT cross the border....an then another month before they sort out the exchanges "in the sticks".. >:(
Switched off router for 15 mins = nothing
updated firmware = nothing
sync at 7808 d/l speed of 240kbps :(

Well, I was starting to think that but patience man ... good sync. speed btw ;)
patience is running thin ;)

Quote from: Xbandito on Apr 03, 2006, 16:57:19My internet is all over the place.....250kbps then five mins later 80kbps :(
It's network congestion caused by everybody running speed tests.... :P
Hmm I've just noticed that my router doesn't have SNR....been looking at DS Noise margin all the time :/
Is SNR the same as DS Noise margin, if not how can I find out what my SNR is?
Kuja, are you able to "telnet" into your router ?
Quote from: kuja on Apr 03, 2006, 20:15:15Is SNR the same as DS Noise margin, if not how can I find out what my SNR is?
BT require a minimum SNR to allow you to sync at any given speed (I think it's 6dB). Noise margin is how much you've got in excess of that minimum.
So your SNR can go down to 6dB without worrying, that's equivalent to a noise margin of zero.
Does that help?
Can't help with finding out the actual value, I'm assuming the 6dB figure. Xbandito may well come up with something, he knows more about telnetting in to a router than I do!

Not sure m8, I have a Netgear DG834 v2..

Cheers for that m8, at the moment the DS Noise Margin is around 1-3dB, hopefully thats ok.
Well, how I telnet into my router may be different to other users... :)
Bring command prompt up, type in telnet 192.168.1.1 <enter> (usually this is the ip of your router)
login and password will come up and if you have not changed them, they are admin , admin :)
now this bit may be different on each make of router, I am not sure
get dsl params <enter>
and you should have all imfo there -:
local line atten(db) = 29.5
local snr margin(db) = 6.0
I'm getting this m8:
Connecting To 192.168.0.1...Could not open connection to the host, on port 23: Connect failed
Kuja, you don`t need to Telnet your router, stats are already there for you ;)
However, just to see if you can, copy this http://192.168.0.1/cgi-bin/webcm?todo=debug and paste into browser, see if you get a message "Debug Enabled".

For the DG834, to enable telnet, go to http://192.168.0.1/setup.cgi?todo=debug . Which will display the message "Debug Enabled". Telnet will remain active untill the router is restarted. ;D

Checked mine this morning
DSL Speed 448 Kbps Upstream, 2592 Kbps Downstream
Well i`m happy already because i have just gone from 1mb to 2067 Kbps ;D
DownStream Connection Speed 4416 kbps
UpStream Connection Speed 448 kbps
Me to Mark, have to wait and see if it gets any faster.
Well not that long ago i was stuck with 512 so this is great for me :banana2:
I'm getting;
DownStream Connection Speed 5792 kbps
UpStream Connection Speed 448 kbps
here.
1.88 Mbps (1922.9 kbps) from the IDNetters speed tester, however. (Planned for release shortly :P)

Thanks Adam, that worked.
However, I'm not getting any login prompts etc, its not accepting 'get dsl params either'

Any ideas? :)
Open up a command prompt and type in at the prompt telnet 192.168.1.1 or 192.168.0.1, depending on what your router address is, there will be a prompt for password, enter it (you won`t see anything on screen) then copy this , right click beside the hash and paste:

Any good? :D
Very good :)
You may see a slight drop in sync speed during peak hours if your SNR drops below 6 but it shouldn`t affect throughput.
Begs the question, is anyone actually getting a throughput anywhere near their sync?
Well i`m not happy cos i am back to 1 meg at the moment >:(

I'm getting about 650kbps -> 700kbps from http://gamefiles.blueyonder.co.uk
Not settling at a constant speed, but its spiking between the above rate :)
I'm not complaining though! :-* ;)
Same here Kuja, can`t complain at any extra speed for no extra cost! :)
Mark, BT had informed us that once a line is Maxed, it could take 75 minutes to increase throughput, but for reasons unknown this has not happened in some cases. :\
Oh well at least i had a few hours at 2 meg ;D
Ah but maybe it`ll stay the same, is a cup half full or half empty? ;)
Well i shall blame BT whatever the outcome ::)
Just saw the craziest thing ever,
Noise Margin 2147483647 db
when then drops to;
Noise Margin 0 db
Randomly. :-\
Adam
So it wasn`t just me?? Can`t remember exact figures but it was mighty long ... now 1dB so I`m expecting an auto-resync ;)

That's a Netgear router, right? There's an error in the firmware, it's not "dropping" to 0dB, it's rising from -1dB. The 2147... is a mis-representation of -1 in binary. If it's a DG834, I think the later firmware, which you can get from the Netgear site, will fix it. Amongst other things ;D
I`m using a 632 and from what I can tell, firmware v3.6.0 (I`m using v3.4.0) only adds ADSL2+ support so I`m not gonna bother with it.
Reading the Netgear forums, it appears that some folk have had trouble with it. It does after all warn you not to install it if you aren`t on ADSL2+ :)
Running the latest firmware for my netgear here. :P
The sync speed has dropped by ~900k since then though. :-\
Adam
I`ve been synced at 7.008Mbit for 25.5 hours now, SNR actually dropped to zero last night but it didn`t resync ???
SNR is at 8 now ... Mr Saffron pointed me towards "crosstalk*" last night, I had been blaming contention for the drop in SNR during peak times but apparently contention does not alter SNR?
*Crosstalk is the term given to a scenario whereby other peoples telephones, extra electrical equipment (street lamps etc), atmosphere can affect your line quality*
