Hello I have an Airport Time Capsule that seems to randomly shut off every 24-48 hours. Totally unprovoked, sometimes while wifi is in use and others while it isn't. Have to unplug and plug back in the power cord to restart the thing. Have had it plugged into a power strip, two different wall outlets, a surge protector and ground check strip all with the same issues. The previous wifi router had no issues with the same plug, strip, etc. Any help would be appreciated.
