Airport Extreme Card to 3rd Party Base Station? Help!

[Danmation]

I just installed an Airport Extreme Card for my Dual 2ghz G5 PowerMac.

I have a Linksys Wireless Router in my house that works fine w/ our other laptops, etc.

For some reason, none of the dozen or so wireless networks in the area show up. The airport card seems to be hooked up fine, and is being recognized by the OS, but no clue on how to get my networks to show up, even if I type the network name and password in.

Is there something I'm not configuring properly? Or is there something I don't know about compatibility between Airport cards and 3rd party wireless routers?

Thanks for any help out there.

Well, try turning off the security on your network and then see if the G5 can recognise the router. This isn't meant as a permanent fix so much a means of checking if it's a problem with the security protocol/settings.
