The airport connection to my DSL modem on my PowerMac desktop computer suddenly stopped working last night. When I try to reconnect it says there's an error joining the network. It worked perfectly until last night and the password is entered correctly. So I assumed the dsl service was down, but my Powerbook connects with no problems and operates at full dsl speed, so the problem is clearly with the desktop machine itself, not the dsl service. I have tried over and over again to connect the desktop to the wireless network, but it just says "There is an error in connecting to the network." I can see all the networks listed (mine and my neighbors), just can't actually connec to mine. Is it possible that the airport card in the desktop machine just suddenly went bad? Any suggestions on things to try, or do I need to replace the airport card? I’ve tried rebooting the computer and restarting/resetting the dsl modem with no luck. Thank you.
