Setting up Netgear WG111v3 USB Wireless Adapter

My brother recently purchased a Netgear WB111v3 USB Wireless Adapter for his wife's G4 (10.4). I'm not exactly a newbie, but I cannot seem to set up the network using the system preferences. The Netgear software installed fine, but the adapter is not showing up in the network panel. The built-in ethernet had a flaky connection to their DSL router and the machine has been moved away from it so there can be no ethernet connection anyway. Is there a utility available that will assist in set up or can someone give me the necessary instructions. She's driving us both nuts (my brother and me) to get this connected to the internet. (The machine is old yes, but the hardware is a tank and still works.)
