I have an 3Com OfficeConnect ADSL Wifi Router and since I have added an iMac and a PowerBook, after a while it freezes and I have to reset the router. It can happen randomly with web browsing and file copying from a PC. I am a switcher and trying to move many gigs of MP3s off my PC and failing as the network freezes. Because of this Finder freezes and I have to relaunch it and it seems to take an age to relaunch. Edit: Finder will not restart, and I can't log off. Just because of a network error Finder chucks a wobbly... hmm, is this supposed to happen? Can anyone help.
