We lost power for a change last night and while I thought everything was working when I left for work, my wife ended up having trouble with connectivity and the cable box. They are not connected in the same place so I ruled that out while troubleshooting over the phone… After running through a few things and a reboot I was stumped on her computer.
When I got home I discovered the problem.
My main airport is connected to a switched outlet temporarily while some work is being done in the house and it must have been switched off at some point during the day. It never occurred to me to even check this since Ashley was reporting a full airport signal. The signal was coming from an Airport Express… not connected to anything. We use a few to extend the signal around the house and clearly they appear normal even if their home base is down… doh!
The cable box eventually decided to cooperate as well…
