I have a Scientific Atlanta Webstar cable modem. The internet & stuff works fine for a while then after wards the data light on the cable box keeps flashing even tho i got nothing else running, & when i try to connect to any web sites it doesnt work i have to end up restarting the pc. i have checked for hackers, no sign of em. what could the problem be?? ive even installed new drivers. Another thing is that i use Mirc & it seems to be happening when im using that.
