Until now, I used TP-Link ARCHER C80, to which a LENOVO tablet was connected via WiFi and TELEKOM Internet TV was running on it - without problems.

After switching to ARCHER AX72, this TV crashes 3 times within an hour with the error "loss of internet connection". After about 10 seconds, the connection is restored and the program continues. However, these outages are annoying.

On the old device, the tablet connected to WiFi via the "2.4G" band. On the new one, it's via "5G" - the fact that the tablet can't handle it on this band can't be the source of the problem.

Both WiFi "2.4G / 5G" have the same SSID and the band is assigned automatically by the router. I would like to set it hard for this client to "2.4G".

Or the problem is somewhere else.
