Unstable adsl connection?

[Glaucus]

My parents have had an unstable Internet connection for ages, just randomly pops up unable to connect. Is there any way to test the line and post results for people to look at?
Or see if the problem lies in the line/router/computer.


Happens numerous times a day and does reconnect after a few minutes. Running vista and a Linksys wag54gs

Does your router have a connection status section? We could do with figures such as connection speed SNR etc which you can hopefully find. With that info we can better see what is happening. Also where on your phone system is the router? Is it connected at the master socket or extension wiring?

doesnt seem to be anything with snr, or any logs.

Just this

Downstream Rate: 2016 Kbps
Upstream Rate: 448 Kbps

Encapsulation: RFC 2364 PPPoA
Multiplexing: LLC
Qos: UBR
Pcr Rate:

Seems like a very basic modem then. I thought SNR ratios and attenuation were all pretty common things for modems to display.

Anyway I found this..

I found this (you have to scroll right down to the end) at http://www.mdibb.net/misc/linksys_wag354g_hidden_pages/

Turn debug on:
http://192.168.1.1/setup.cgi?todo=debug

start telnet:
telnet 192.168.1.1

type in command:
adslctl info --stats



So opening a browser window of "http://192.168.1.1/setup.cgi?todo=debug"
gives me a page saying "Debug Enable!" - after I have got through the user id stuff.

Tnen
Run|"Cmd" to open a dos window
"telnet 192.168.1.1

and it responds :

"BusyBox v1.00 (2005.12.07-10:11+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.
#"

I Enter " adslctl info --stats"
and ... well I get:

Thanks, didn't get round to doing it before I left. But next time I'm back I'll give it a go. Might be a few weeks though.
