Nighthawk Rax40 router stops sending the beacon (SSID) after TP kasa devices connected to it's wifi.

Rax40 Router purchased 5 mths ago, Firmware v1.0.3.64_1.0.1  Router has been working fine for my other devices (Smart cameras, Tv's, PC's, Phones), but I recently purchased TP-Link Kasa smart switches (HS210).  The process for setting these up involves downloading Kasa app on phone, connecting first to the switches, then having them connect to home wifi network.  At this point, when the switches attempt to connect to the Rax40 home wifi network, the router just stops sending out its SSID for all wifi channels (both 2.4 and 5G)...all client devices in the house are dropped.  Calling TP Kasa tech support, they indicated this is a KNOWN issue with Netgear Rax40 router and to contact Netgear.  I ended up connecting an old Media Link router as an access point off my Rax40 and connecting/setting up the TP-Link smart switches through this access point...No Problem.  Thing is, I don't want this additional access point/router.  When I contacted Netgear I was of course told I was beyond the 90 days, so had to go through their other support method and the only suggestion they had was to disable the Ax feature...which even if it did resolve the issue, the main reason for purchasing a wifi 6 router was to have that benefit.  Anyway, it did not resolve the issue.  The next suggestion was I needed to purchase a Gearhead support contract!  Very disappointed and at this point am ready to move on from Netgear for a router that supports smart home devices.
