Doesn't it figure?
AT&T insisted that I spend $80 getting a new DSL "modem" since they were certain the one I had (made by ActionTec) was causing my connection issues. The unit they sent me is a Motorola 2210. After receiving the new unit I configured it for use in my environment, then set it aside waiting for an opportune moment to make the swap. The next day, magically, all my connection problems went away. I've had over a week of solid uptime with 0 drops, still using the old ActionTec. The Motorola is still sitting in my office, unplugged.
Magical little boxes: they can fix a problem just be being in the same house!
