This was happening to me, I called them a few times and they finally came to the conclusion that my router was getting bad signals from the modem due to the firmware or possibly just the build of the router itself. After asking, they confirmed that it is a widespread problem.
I switched to my D-Link router (wireless N) and haven't had any problems since then. Great router, I miss DD-WRT though.
