I've been using this plug for ages with no problems.  All of a sudden, it stopped connecting to wifi.  After a factory reset, I can't connect to it at all.

More info:

Did a factory reset by holding down the top button for 10 seconds until rapid amber flashing, and now it's in setup mode (flashing between green and amber).  The Kasa app will not connect to it.  It keeps asking me to go to my wifi settings and connect to the "TP-Link Smart Plug" wifi.  Nothing TP Link ever shows up.  I see a dozen other WiFi access points, but nothing TP Link, even after unplugging and replugging multiple times and factory resetting multiple times.  Also, I am less than 2 feet away from the device, so I know it's not a distance thing.

Anyone else have this problem?  I searched the forum but couldn't find any answers.
