yeap, i have the same problem here, since i moved to vista. are u running vista?
everything works fine, until i start bitcomet. even before bitcomet has a chance to resume the jobs, my connection totally dies (100%). it's like my wireless adaptor just disconnects from my router, and yet it is connected (the connection doesnt drop). I imported the settings from my XP bitcomet installation where everything works fine. if i run the same jobs, the same settings in my vista bitcomet, everything dies. ??? very frustrating. even if i let bitcomet run for less then 5 seconds, the connection still dies, and stays dead for 5-10 minutes. then comes alive by itself??? although all DNS based services die, all IP services stay on and work fine, which make me think, bitcomet kills the DNS addresses or something. Skype for example works fine, or FTP apps. both apps only use IP adresses, no DNS involved.
