I have a 24" iMac with the wireless n enabler installed. I have my appletv two floors above it and my new base station one floor above it . . . . here's the problem . . . the iMac doesn't seem to be able to maintain the sharing capabilities with all my other computers including my appletv . . i have no idea whats going on and it's kind of annoying to have to go down to my office to reset everything to get everything to work!
