Odd one this. Have setup wireless netowrking previously on my machine (Through a linksys WRT54G Broadband router), then added a Linksys PCI adaptor to another machine in the house (WMP54G) and successfully got the other machine on the net. However since installing SP2 the network adaptor in system devices is missing. So when I try to set up home networking, I am unable to do so as the wizard can not find a network adaptor.If I go to system tools, system information, there it is. But via control panel, system information, device manager, nothing??? How is it that the computer connects to the net with no problems, yet can not create a home network because it can not see the card? When I try running the setup disc supplied with the PCI adaptor, it refuses to run. No error messages, just does not run. (This is on the machine with the PCI adaptor installed ...... with fitted and working but not showing in the device manager
