I have 3 computers in this home where I currently live. One mac and one XP machine connect to the WiFi network just fine. The encryption is WPA2 Personal. This 3rd desktop always gets assigned the IP 169.254.228.249, subnet mask 255.255.0.0 and all the other parameters are not there. Windows reports Limited or no connectivity. It's running XP Service pack 3, the WiFi card is D-Link Airplus G DWL-G510 revision C. When I boot into Ubuntu from a Live CD it connects to the network just fine, it gets an IP something like 192.168.2.32, a subnet mask and a DNS address, and I have internet access so I know it's not a hardware problem. I tried reinstalling the WiFi card but to no avail. I tried setting the parameters manually and then it doesn't say limited or no connectivity but there's still no internet access. Reinstalling windows is not an option and I don't know the username and password for the router. Has anybody got an idea how to fix this?
