The router may be becoming overloaded.

Disconnect all the smart plugs but one. Leave that connected to see how it responds.

When the issue happens, what is the status of the LED light?

@Tony I'll try that but it is an enormous pain as to access each plug requires moving furniture or getting a out a ladder (WHY I got the smart plugs in the first place!).

However, they have worked for two years and ntohiong has changed and every other smart device in the home works fine so I can;t imagine it's an issue with the router.  Which I have also reset and have had checked out by the service provider.  

POnly the Kasa plugs have gone wonly.  And they all went wonky at the the same time.  And will phase in and out of visibility on the app.  Sometimes appearing after a refresh, sometimes not, somtimes abeled only as "local" only to have the "local" go away and everything is fine, for about ten minutes.  

Based on that everything else still works, the router is fine, resets have no effect, and it is ONLY the Kasa plugs having an issue, and the issue dtarted for all devices simulataneously—I have to beleive it is a problem with the product or the network ID service.  

Both LED lights remain green and steady for all devices during the trouble.  Supporting the hyposthesis that it is not a local network issue.
