i tried to reduce the RF Bandwith of the WLAN Part of some mikrotik product. 20, 10 and 5 MHz work fine, when i try to configure something else, esp. below 5 MHz there is an error message that there is a need of a higher licence level. I tried level 3 and 4, both lead to the same err message.
With licence level is needed to freely configure the RF bandwith?
With values are possible?
