Hi, on ap (rb912, ros 6.19) i have channel 5720 in uzbekistan. But on some clients (various sextants) it is not under Uzbekistan. But on some rb911 it is. Why?

most likely you have different wireless package in these devices. what is the channel width that you use? make sure that you use the same type of wireless package in all of them.

802.11ac devices can only use wireless-fp package, so you should use this package on the others also

thanks activation of wireless-fp helped
