I have a wireless network set up in my house (PC and Linksys router - WRT54GS) and recently purchased an Airport card for my G5. The airport card is installed and recognized by my Mac. My network in the house is up and running. But when using my Network settings to try to connect, I'm unable to. The network assist scan is not picking up the network. Typing in the network name and password isn't working either. Any thoughts on what to do? (I'm new to wireless networks)
