Thomson Gateway TG585 v8 & SN Margin

I've just picked up a sealed PlusNet 585 v8 for the handsome sum of £10 and finally connected to my new C&W LLU service. The stats aren't bad, but nor are they great:

Uptime: 0 days, 0:21:50
DSL Type: G.992.5 annex A
Maximum Bandwidth (Up/Down) [kbps/kbps]: 1,107 / 16,012
Bandwidth (Up/Down) [kbps/kbps]: 1,023 / 15,834
Data Transferred (Sent/Received) [MB/MB]: 4.99 / 73.66
Output Power (Up/Down) [dBm]: 12.0 / 17.0
Line Attenuation (Up/Down) [dB]: 8.0 / 13.0
SN Margin (Up/Down) [dB]: 10.5 / 10.0
Vendor ID (Local/Remote): TMMB / BDCM

Does anyone know if there is a way to adjust the SN Margin at the router end? DMTool isn't compatible with the 585 v8 running Software Release 8.2.7.8

There isn't .

Tweaking is done using telnet. DMT is a nice GUI front end but does everything through telnet, as does any similar tool like RouterStats.

Technicolor/Thomson disabled telnet in their firmware in all versions after 6.1.4.3 on the 585v6. Believed to be at the request of Tiscali as user-tweaking annoyed them.

Grrr. Well, I can telnet into this 585 v8 - I've done so to set OpenDNS as the default.

I wondered if this sort of thing would be possible on the 585 v8:

Tweaking SNR margin to make your ADSL connection more stable

telnet isn't disabled. I can telnet to my bebox that is on firmware 8.something

But how to play with the SNR ?

OK.

get to telnet. Then try

adslctl --snr 50

Apparently this is still disabled, but I did it from memory, incorrectly anyway. Should be

adslctl configure --snr 50

It's adslctl that's missing actually.

That's good news. It used not to be possible on the v6 and v7. Sounds as if someone has decided to reinstate it .

Unknown command.

As per BatBoy's post.

Its adslctl that lets you get the stats as well .

adslctl info --stats

LOL! Should have guessed.

Oh heck !

I've been spouting the Netgear adslctl, which IIRC also applied to Linksys. I could have sworn that was what I used on 6.1.4.3 though? Are you sure adslctl doesn't work on it as well?

I swapped a few times between that and 6.2.29.2.

Time I had a memory tonic .

Telnet, and hence DMT, did work after 6.1.4.3, but as you say - it was the noise margin tweaking that didn't, due to the command being disabled.

Nope

Which is why it's a different version of DMT .
