If you search the forum you will find these can't be set and have been requested for a long time... yet Mikrotik doesn't seems to be listening or there is some hidden reason why these can't be changed (their own wireless drivers?). Especially beacon interval would be handy to modify, but NOPE.... not possible.
I didn't think it was possible for mikrotik to still not have implemented it after all these years...
How does it make sense to have a bunch of esoteric settings that no other ap has/needs, but the absolute basics (that even my 10 year old, $15 tplink has) are missing?
Does anyone at least know what the current values are?
