Here's what I got and what I'm trying to do.
iMac w/airport card
iBook w/airport card
Airport Express
Compaq PC (Win XP) w/Netgear 54 Mbps Wireless PCI Adapter/WG311
Comcast Cable Internet Service
I want the two Macs and the PC connected to the Airport Express wireless network. The Apple store said this is doable. All the Apple products function perfectly on the wireless network. I installed the wireless PCI adapter on my PC and took it to my work where there is a D-link wireless network. Connected to the network...meaning the adapter works fine. When I boot up at home the network icon on the tool bar has an "X" on it and in the network connections page the devices status says "Disconnected"?
Maybe the problem is I don't know wireless networking or networking in general. What do I need to do or what am I not doing? Help Please!!!
