...the wireless connection is set to "on" or "enabled"....also check whether "local area connection" is "on" or "enabled". You can do this at Control Panel>Network Connections. If byou cannot see these two objects, you have other problems. Try running the Network setup wizard... By the way, what icons do you see at the "tray" or "information area", i.e. near the clock at the right end of the task bar ?

I can now plug in the modem directly as I just had to repair some driver or something. But the wireless is hopeless. The card shows up in device manager as working. The light on it is green and nothing seems to be at fault. It's just very strange.
