Ask AT&T if that router will provide a QOS report. If it can not, ask them to provide a QOS report from their hub.

The QOS report (Quality Of Service) is a report that shows how long the link was established, when it went down and for what reason. Usually, when AT&T switches to static addressing, they also switch out the router and everything starts to work OK. I have run into a few AT&T Uverse problems that ended up being a bad module in a SLiC 96 in a concentrator. Who actually is responsible for the local connection? If you have a LEC involved, you may need to have the circuit verified by the LEC first.
