so i got a new pc (got rid of my macintrash) and hooked it all up and used my roomates internet to make sure that everything worked correctly. since then i made my own subscription to the net. at first the connection would hold for about 5-10 minutes and then shut off and have difficulties reconnecting. now it it refuses to even try to sync up and the modem shows no activity whatsoever. i contacted the provider and they said the line was fine (tested it out themselves after numerous complaints) and i have again tried my roomy's connection to verify that the modem and phone line are not the problem. what is going on?!
