Comcast tech support are a bunch of half wits. I had similar problems, dropped connections, slow speeds, etc, and the phone support had me exchange the modem several times. Finally someone came out and the problem ended up being the in house cabling. More specifically, we had old aluminum switches. Comcast swapped them out, free of charge, with some nice gold ones and problem solved.
As far as the nic card, that was probably erroneous information also. My nic will flash orange if its not receiving a signal when the network cable is plugged in. So before you run out and buy a new nic, as cheap as they are, check your documentation as to what a blinking orange light means.
