AX3200 5Ghz Wi-Fi issue

Hello

Got a problem on Xiaomi Redmi Router AX6S

Wi-fi 5Ghz stop broadcasting network.

It happen on 24.10.5 owrt ver. I tried to update to latest version(clean instal, flash stock, then owrt again), but it didnt help.

Also tried change channels, countries(only for test), change to open network and back to protected.

Configs:
