PCI Airport Extreme won't connect to home WIFI
I have a Power Mac G5 and we have a home network using a Linksys router & modem hooked to a windows PC. I cannot get Power Mac to work with home LAN w/ WEP password. I have a generic PCI Airport Extreme card I bought on eBay. (shows as 3rd party wireless)
The airport card gives me full bars on the menu. And if I go to Network Preferences, I can choose join networks and my neighbors WIFI show up (locked). When I enter network name & password, it marks it as invalid. I know its correct because I have a Pismo with the old airport card and it works. My brother has his windows PC & laptop and those are both wireless.
I already tried removing the preference list, but not sure if I got all the ones that might need to be removed. Wired ethernet works fine, I'm using it to connect to internet.
TIA
Power Mac G5 1.8GHz DP rev. 2, Mac OS X (10.5.8), 3GB RAM / 160GB & 80GB HD / DVD / OSX 10.5.8
