Are the nameservers correct in /etc/resolv.conf and by not working what do you mean? Is there an error message produced that you can post. Something else you can do is post the output of lsmod from the booted HD so I can see if the module for the card is loaded and in use. What does ifconfig -a tell you from the Booted HD you may want to post that as well. The more details the better.

Can you ping the server or an outside address try ping 212.100.234.54 (The Register website in the UK).
