Any one with a SB6120, got home yesterday and the modem was completely off. Roommate said he power cycled the power strip and moved the power adapter to a different strip with no luck. Meter checked the end of the plug and showed no 12v. This modem is only about 5-6months old. Gotta call Motorola and ask about it. Beware, made in China.

Lucky I had my trusty old radio shack universal power.

Update: I'll when I get home from work so they can get the serial # off the modem
