Output from "ifconfig" shows no eth0 data only lo data so it doesn't seem eth0 is recognised.

The Network Manager Applet 0.7.99 task bar icon shows a red cross alongside it. When Editing A Wired Connection any attempt to input a MAC address greys out the Apply box so the settings cannot be applied.

I cannot get my ADSL2 modem router settings page to display on Firefox or Chrome.

I've reported the problem to bugs@knopper.net as advised on page 32 of Linux Magazine 113.
And you still don't give us any detailed hardware info, like the output of lspci -v..
Quite often, it is possible to get around hardware detection/initiallization problems by either turning off parts of the automatic procedures or doing the initialization manually.
