I'm getting this same issue, and I also have an AT&T Motorola modem. Considering buying a router in hopes that it will act as a DNS relay and protect me from whatever quirk is causing this (I'm having serious internet withdrawal :). Going into the modem interface and asking it to resolve a name directly seems to work.
