I am wondering if his ISP could be doing this - he has received a warning letter about bitorrent. Could the isolate a single computer behind a NAT router?

This is the results from dmesg:

I have tried:

- to set proxy settings as "Direct internet connection"
- disconnecting power to (including 30 sec wait): modem, router, computer + unplugging ethernet from computer
- Live CD (he only had an old one 7.10) which also didn't connect to internet, but as I am remote, I couldn't do any more. We are downloading a 10.04.1 iso for him to burn tomorrow, and will try that again.
- Uninstalled Crashplan which was the last software that we installed (and it was working ok).

I am currently ssh'ing into another computer on the network that IS working, and then ssh'ing into my Dad's computer - including a VNC session (tunneled through both machines and router).
