When I'm running the tether on my 8310 (ATT/Cingular) it will be running just fine, then all of a sudden it stops and shows "limited connectivity". Sometimes it will come right back, other times it's gone for over an hour. I've tried unplugging both from the phone and computer. I've restarted the computer, but nothing seems to have effect. I'm running it on a HP laptop with Vista 64bit.
