I'm trying to connect a Power Mac G4 with an airport extreme card to an existing home wirless (wi-fi) network running off a linksys wireless G router but I can't get the Mac to see the network at all. The airport status indicates that airpor is on but not associated with a network. I've tried connecting, using the other network option and entering the WEP key info but I get an "error connecting to network' message. I'm pretty sure I'm using the most recent version of airport software and I updated the firmware on my wireless router to the most recent version. I tried disabling the wep and was still not able to see the network. Any other suggestions? Thanks.
