There could be a strong wireless interference around you on 2.4GHz band - you can check that with:

or Wi-Fy Analyzer.

If that's the case you can select the least crowded wireless channel and set it in the AX10 wireless settings instead of using Auto for Channel.

This should improve your wireless experience.

If that doesn't help try these wireless settings:

It's worth checking the wireless signal strength for every wireless client - if the wireless signal is weak this may cause the issue as well.

Thanks for the reply. I will do the test as soon as possible. The router is installed in the vacation home and there are not many operational connections in that place. There is mine and the neighbor's connection. If you have other options to try I would be grateful to test them all. Thank you

Thanks for @terziyski's professional and quick suggestions about the issue you are reporting. As per your above description, it seems you are monitoring or managing the smart devices from an outside network and that is not stable, I would suggest you can also try to change the Internet DNS server on the router to Google's 8.8.8.8 or Cloudflare's 1.1.1.1, then monitor again.
