I have a problem with Tapo C125 and C225 cams (Homekit enabled).
Whenever my router reboots (every 3 days) or the cameras lose connection, then my Tapo C125 and C225 cams won't reconnect to Wifi. They are offline then and stay offline forever (blue light blinking fast) until disconnect/reconnect from AC power.

Now I found a workaround:
I had to set my Wifi router to reject 5Ghz Wifi for Tapo camera Mac-adresses, so they won't try to connect to 5Ghz Wifi band. The cams don't support 5Ghz Wifi, but for a reason they try to connect to 5GHz Wifi first, or the router tries to connect to 5Ghz Wifi with them because they are Wifi6 devices.

Now they can only connect to 2.4Ghz Wifi band (because forced 5Ghz Wifi reject) and they do not lose connection anymore, even after reboot. Maybe this is possible to change in cameras firmware, because all my other 40 devices have not this problem and therefore it is not a router problem.
