I'm having problems connecting an iMac G3 to a home wireless network. The wireless router is a Netgear DG834G, connected by Ethernet cable to a G4. The iMac has an Airport card fitted. The iMac is recognising the Airport card, but it is not finding the wireless network -- the network name does not appear in the list of available networks. Does anyone have any suggestions? Is there a 'how to' site I could look at for help? Many thanks.
