Thanks, it could be I should return this machine and get another then. Do you use it for the sorts of things I mentioned? Here general use is fine. Things like email and using the web do not cause a problem, nor even streaming audio which works the wifi continuously but only at a rate of a few packets a second. OTOH, streaming 300kbit/s mpeg4 video with 48bkit/s mp3 audio causes the media player to freeze after 10 mins or so and then the m/c reboots. Or fetching a 1.5 Gig file with: $ wget -O /dev/null http://local-server/gigs That ran for nearly 18 mins, at around 700kbytes/s, after which the wifi went dead, the m/c was warm though it didn't crash.
