Any decent ADSL 2+ modems with line stats?
« on: July 31, 2012, 03:51:07 pm »
Are there any decent (i.e. can hold a long line) ADSL 2+ ethernet modems that allow access to line data (including bit-loading) when running bridged or half-bridged?

I've been using a Netgear DM111P, but that doesn't seem to give bit-loading and the main web interface is a right pain to use without IE (no use in Mac/Linux environment).

I've been having some line issues, and the extended diagnostics would really help. I've looked at the D-Link DSL-320 and Draytek Vigor-120 but they don't appear to have a lot in the way of diagnostics.

I could use a modem/router, but I've always found these to be less reliable in the past (frequent crashes / lock-ups) when running for extended periods.

I'm using the Vigor 120.
Whilst it has limited diagnostics via the web interface it also has a telnet interface with way more info available.
E.g.
Code: [Select]

Personally I've found the web status page to be sufficient.

Thanks Steve,

That's exactly the sort of thing I'm after. I've got 'something' that generates lots of noise on the line at times at this allows me to see where in the spectrum. I can easily script collection over telnet.

What IP did you use to get in? I can't see anything in the manual I downloaded about telnet.

The telnet interface is somewhat undocumented, I guess because most people would never use it.
There is information available on Drayteks site though:
http://www.draytek.co.uk/support/kb_vigor_telnet.html

It's on the the same IP as the modem web interface and uses the same user/pass.

It looks like it would be possible to configure the modem into a brick using the various commands so be careful. It's interesting to see that you can turn it into a router by enabling NAT and DHCP etc. It uses a router style SOC like any other modem/router.

Yes, telnet is generally very good for breaking things, which is why it's often hidden ;)
