After every power outage the smart mini plugs do not reconnect to the router.   Instead, they all have a solid yellow light and must be manually reconnected.  This is a hassle when I am home.  It makes these plugs completely useless for my seasonal home when we are away for extended periods of time.

I read one post which hypothesized that after a power outage, the smart plugs try to connect to the router before it is online.  That is, the plugs are faster than the router.

Any ideas how to solve this problem besides putting a backup power supply on my router?
