I can't seem to connect to either the Ethernet or Wi-Fi. I can connect fine from my android phone. I'm running Ubuntu 15.10 on a Thinkpad T60.
Edit: The ethernet and wireless are separate problems, and the ethernet problem has been solved.
Wifi adapter is Intel corporation PRO/wireless 3945ABG.
The results of the wireless info script are too long and stackoverflow won't let me post them, so here's a link.
