Title: Anybody Max'd yet ???
Post by: Xbandito on Apr 03, 2006, 09:10:57
Anybody been regraded yet ??, not sure if I have...if I have it has not made any difference to download  :(  but upload...hmmm
http://www.adslguide.org.uk/tools/speedchart.asp?id=3160abda10a5ec8a5716615e790

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 ???
Title: Re: Anybody Max'd yet ???
Post by: Jeff on Apr 03, 2006, 09:49:28
Yes! Synced at 6528kbps :)


Speedtest (http://www.adslguide.org.uk/tools/speedchart.asp?id=12d46b7a10a5ef008e145dd0f36) disappointing though :(

Just found this on Adslguide -:

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

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! ;)

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  :-\

yeah no doubt, but i've been having the same with 2mbit recently (speeds down to 70-80kbps)..could it be down to contention?
Title: Re: Anybody Max'd yet ???

Yes, most definately exchange contention. I`ve been suffering it for months :(

Switched off router for 15 mins = nothing

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?
Title: Re: Anybody Max'd yet ???
Post by: Xbandito on Apr 03, 2006, 20:45:09
Kuja, are you able to "telnet" into your router ?

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!

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

Kuja, you don`t need to Telnet your router, stats are already there for you ;)

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

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:

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?

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 :)

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
Title: Re: Anybody Max'd yet ???
Post by: Jeff on Apr 04, 2006, 23:47:25
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+ :)
Title: Re: Anybody Max'd yet ???

 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*
