Kasa smart switches and smart plugs flapping on wifi after router patch
I'm having an issue with all my kasa smart switches and smart plugs (multiple versions, all firmware up to date) and router patches. I have an ASUS AX88U router on firmware 188.8.131.52.386_44266 dated mid 2021 and it works fine. However if I upgrade the router to any newer version of the firmware all my tp-link smart devices begin intermittently dropping their wifi connections. Generally the connections are dropped every few seconds to every few minutes.
I've tried reseting the devices, resetting and reconfiguring the router on current firmware, and disabling 5ghz radio and I always get the same symptoms. All my other devices work fine on upgraded router firmware, it is ONLY the tp-link devices that are failing on current firmware.
