Most Peculiar

Bizarrely, every time my AC comes on, my HDMI router blinks to another source. I'll be watching something through my cable box, the AC will come on and suddenly it's switched to an unused HDMI input.

I can hear my thermostat click from where I usually watch TV. It will click, and I lose the signal. I have to grab the remote and switch it back.

Power spikes (or drops) can cause weird effects on stuff. You might want to pick up a small surge suppressed UPS and plug the router into it.

It's plugged into a surge protector. If this behavior continues I'll have to move the wall wart to a receptacle on my UPS. That will require some (read: a huge amount of) untangling.
