Change Ap frequency and CPE auto connection

I need to change frequency for my 4 Access points
I have 120 stations that should reconnect automatically to them without going to customer side.
Here wireless interface settings of stations: should I change configuration?

someone can help me?

No need to change anything.
The station will scan all available channels.
Just make sure that you are using the same setting for country in ap and stations. I don’t see it in your export which could mean it is set to ‘no_country_set’

country is properly set, I don’t know why it does not appear on detail screen

Then just change frequency on AP and all stations will reconnect in a few seconds.

I hope it! thanks
