Ok I'm going to give it a go! Here goes nothing...Following up here to confirm that my IoT devices are finally stable after several months, thanks to the 9.0.1.4_386_46197 beta firmware mentioned above.
Upping my Beacon interval to 1000 solved the issue I was having with all my TP-Link smart switches suddenly dropping and reconnecting to my AX88U/AX6000 router after upgrading the firmware. That was driving me crazy. I was all but convinced there had to be a bug in the latest firmware upgrade. Thank you for all your hard work with finding a solution and sharing.I had the same problems with my 2.4 GHz IoT devices (mainly ESP-based), more than 50.
After tons of tests I found the solution, at least in my case:
Beacon interval: 1000
DTIM interval: 1
Save and reboot.
Too frequent beacons cause freezing of many cheap wifi chipsets.
