Since i got this new PC, every now and then i get dropped from my net connection. i'll be surfing and like a lightswitch, off it goes. Thing is, if i do a reboot it works fine again. I've tried going to the net connection doing a repair, or a disable/enable. but the only thing that works is a reboot. Any ideas? kinda annoying. Never did it on my old PC. thank god. Reboots took a half hour!
