airport card cant see network

I have recently moved. I had no issues with the my network on my G5. We moved, I bought an Airport Extreme and set it up through Qwest DSL. My G4 laptop, my iphone, my roommates G4 laptop and his dell laptop all successfully see and login into our network just fine. However my G5 doesn't see any network available. Like I said, in our old spot, everything was fine. Any Suggestions? Thanks in advance.

Wireless Card Type: AirPort Extreme
Wireless Card Locale: USA
Wireless Card Firmware Version: 405.1 (3.90.34.0.p18)
