I have a self-built desktop running Ubuntu 10.04 LTS. It is connected by an Ethernet cable (not wireless!) to a Apple Time Capsule (identical to an Airport Extreme). The Time Capsule has an illuminated LED on that port indicating that it is connected to the machine. However, the computer cannot access either the network or the Internet, and my other computers don't see it on the network. What could be causing this?
