I have had trouble only this week with a couple of wireless desktops in my home. It seems to be affected by one of two things (or both). I added a third wireless desktop recently and it seems to cause problems whith the other wireless connections after it was added. Is this and issue? Also running Windows XP SP2 on all machines. The other possibility is the latest security update for IE7 which was pushed to the other two machines this week. I unistalled the patches rebooted the machines and all seemed well untill I turned on the third computer and one of the other two machines lost its connection and then got it back after I turned off the third computer.
