Alright, I have an older G4/400 with no AirPort capabilities, so I needed to use a Netgear WGE111 Wireless Game Adapter instead of a wireless NIC. Anyway, I got the AirPort Express all set up and it's working fine BEFORE I run the Setup app. Right now, it's called Apple Network 73781 or something like that. Once I run the setup app and rename the network and set a password, it doesn't work anymore - neither of the 3 computers in the house see it. is going on here?
