I had moved to James Island, SC and actually carried the Comcast I had over. But I ended up the last customer on the line that was probably over serviced. I ended up replacing it with the AT&T Dry Loop DSL 6.0. I am happy that I get 80% plus of the service at any given time. The installation of the self install kit was easy. I was up and running in less than 20 minutes of opening the box to the kit.
UPDATE: I was having issues with Comcast for several months who could not fix a bridge tap until I had them reduce my tv service to basic basic cable. They were forced to fix the bridge tap problem after a few months, Comcast offered me a great deal on the Performance package.
Sorry AT&T, I held out for Uverse which seems to be awhile when it it comes to my neighborhood.
