I have a Dell Latitude 610 laptop -- had it for about 2.5 years. It's set up to dual-boot Kubuntu 9.04 and Windows XP (SP2). For a long time, I was able to connect to my home network or other networks either wirelessly or by Ethernet. The computer has both capabilities built-in.
Several months ago, however, I found myself unable to make a network connection. First, it was just the wireless gone bad. I couldn't connect to any network with either OS. I am fairly certain it's the computer, not the router, as a neighbor was able to see and connect to my home network with her wireless machine. At that time, though, I was still able to plug in the Ethernet cable and get into the network.
A few weeks later, though, I found myself unable even to connect via the Ethernet cable. I know it's not a cable or router problem because I can use the same cable and the same jack on the router to connect a different computer to my network; the computer is the only variable. Again, the failure is OS-independent -- can't get on-line with either Windows or Linux.
Anyone have any suggestions how I might get this machine back on-line?
