I just built my father a new computer, and for some reason he has to keep repairing the connection while he is online. I didn't have a problem while I was downloading drivers and all here at my apartment on my routered cable connection. He's had them ever since he got it home. He's on DSL with my mom's computer where the 4-port DSL router has DHCP. I've never seen this before, can't find it on here, google, or MSKB. Any clues?
