Hello,

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?

The Mikrotik support send an email regarding this topic. The answer is that only parts with contains an Ateros AR92XX Chipset for wireless are able to used unusal bandwith. I try to get one and test it.
