No matter what settings I use for my "normal wifi network", I can't get the router to authenticate a client.  However, the "IoT network" works just fine with all the different SSIDs, PSKs, and security settings I have tried.  So I have setup the IoT SSID/PSK as my normal network.  Seeing all of the encrypted packets being sent back to Chinese servers from my "smart devices" it would be nice to have different network settings for them.  Has anyone else seen this behavior before?  If so, is there a fix?
