Bulldog 16mb ADSL

Hi toy,
from your downstream attenuation figure, you live pretty far from the exchange and i would doubt if you would see much increase with ADSL2+. You MAY, however, be lucky and get a slight increase of 1-2Mbit.
Sorry to be the bearer of bad news. I still think it would be worth the extra fiver a month once SRA is implemented, meaning that you wouldn't get any dropped connections. I would far prefer a stable 1Mbit than a 2Mbit connection that disconnects; very annoying if you play games online or use chatrooms like irc and msn messenger etc.
Definately try plugging your router directly into the test socket though. You are likely to see some improvement in your downstream SNR, especially if you have extensions emanating from your master socket.

HTH

Thanks, im not too bothered about more speed as it usually stays around the 4mbit mark anyway, would like a more stable connection though and SRA sounds like it could do just that.

What do you mean plug it into the test socket?

Cheers

he means your master socket, if you have the NTE5 socket installed you can remove the bottome bracket and plug your modem directly into it like the pic below.

If these are my stats from my router:

Connection Speed 2272 kbps 288 kbps
Line Attenuation 45 db 13 db
Noise Margin 22 db 24 db

What speeds can I expect? On adslMAX they reckon about 6.5mb/s. Does ADSL2+ work differently, meaning better speeds?

Cheers
 
Well the latest is bulldog have overcharged loads of people for the router/modem, when the page was acting up and said payment had been declined.

Ive been hit for 3 payments of £20 , some have been charged £800, its not funny bulldog. !

With my Netgear DG834GT I can Telnet into the router and change the SNR. By doing this I have improved my sync from about 6500 to about 7200 giving an increase in download speed. By trial and error I have found my connection to be stable with an SNR of around the 7db mark. Any lower still gives a higher sync rate but a decrease in overall download speed. rebooting the router restores the default SNR of about 10db.

how do you telnet into ** router? what firmware?

cant wait for adsl2+. thou only bulldog(forget it) and carphone warehouse are at my X. waiting for tiscali.

Your line stats suggest to me that what is detailed below will not improve you connection as you are already at the maximum sync speed. It may be of more help to improve your speeds when adsl2+ is rolled out.

**Warning**

Use the following at your own risk. I have only tested this on my DG834GT and an 8Mb Bulldog account.

*******************************

I am using firmware V1.02.04 but it should not realy matter which you are running. Also as far as I know this works with all dg834 series routers.

First drop this link into your browser. This will put the router in debug mode unlocking the telnet server.

192.168.0.1/setup.cgi?todo=debug
You may be presented with the login promp. Use your normal username and password.

Next open a command prompt window.

START > RUN > CMD

in the window type - "telnet 192.168.0.1" without quotes and bingo you are in.

at the # type "adslctl --help" for the following list of commands:-

Usage: adslctl start [--up] [--mod <a|d|l|t|2|p|e|m>] [--lpair <(i)nner|(o)uter>
]
[--trellis <on|off>] [--snr <snrQ4>] [--bitswap <on|off>] [--sra <on|
off>]
adslctl stop
adslctl connection [--up] [--down] [--loopback] [--reverb]
[--medley] [--noretrain] [--L3] [--diagmode] [--L0]
[--tones <xmtStart xmtNum xmtMap rcvStart rcvNum rcvMap>]
adslctl configure [--mod <a|d|l|t|2|p|e|m>] [--lpair <(i)nner|(o)uter>]
[--trellis <on|off>] [--snr <snrQ4>] [--bitswap <on|off>] [--sra <on|
off>]
adslctl bert [--start <#seconds>] [--stop] [--show]
adslctl info [--state] [--show] [--stats] [--SNR] [--QLN] [--Hlog] [--lin
ediag] [--reset]
adslctl --version
Click to expand...

To set SNR type "adslctl configure --snr N" where N is the value from the table below. The router will re-sync using the new value for SNR. I use a value of N = 50 to get an SNR of 7.2db and a sync rate of about 7200. It may take about 20 seconds for the router to re-sync and establish a connection. It is generally recommended to have SNR > 6db.

N -- SNR(db)
6 -- 4.6
7 -- 4.8
8 -- 4.9
9 -- 4.9
10 -- 4.7
20 -- 5.6
30 -- 6.2
40 -- 6.9
50 -- 7.4
60 -- 8.2
70 -- 8.8
80 -- 9.3
90 -- 10

Type "adslctl info --stats" for router stats.

Type "exit" to exit.

A reboot of the router will set things back to the default SNR which for me is 10db with a sync rate of about 6500.

Enjoy.
 
yea i did a search and found out about it.
