Thanks. Disabled homegroup. Usually takes a few hours before the problem shows up. We will see. I did find a similar thread at: Windows 7 on wired computer prevents wireless connections to router No real explaination to why, but did indicate that disabling homegroup solved the problem.
Haven't seen this in any of the threads, so thought I would post it here. I have a small network running at home. 3 XP desktops, 3 Vista desktops, XP laptop, and a linux box all wired connections to a Cisco router. I also have a linksys WRT54G AP configured for WPA for my wireless devices...
