My wife has a nice new (sort of) MacBook. Everything about it is great, except the wireless (and the casing which I had to have replaced). The problem with the WiFi is this: the signal is constantly lost. I can sit on the couch next to her using my iBook G3 and there is not even a blip, but her signal will go from 100% to 0% to 50% and then back again. This is the only computer in the house with this problem. As I said early, my G3 works fine as does my G4 eMac. Both the eMac and MacBook are running Tiger and all the wireless settings are identical. I recently switched from a WRT54G to the Airport Express because the Linksys died, but I haven't noticed any change during the course of that time. As a matter of trying to figure things out, I did switch the broadcast channel from 6 to Automatic, but it hasn't been long enough to tell if that has made any difference. Has anyone else had this sort of problem? I would think it was an interference problem if any of the other computers were having issues, but they are all happy. Thoughts?
