Hello, I have bought an iMac G4 (late 2002 OSX 10.4.3) with an Airport card and want to connect to the Internet. Unfortunately it shows me no available wifi's but there are some of them with different authentication methods (WEP, WPA2, No encryptions). My other Mac in the same room is able to see all of them. The system profiler shows me the airport card and I've also successfully tested it with the Apple Hardware test. Any ideas?
