RP-AC68U Cannot set beacon interval below 20

Has anyone had any luck getting the Beacon interval below 20? I'm seeing huge performance gains lowering this from the default 100, then 50, and now to 20, but I cant seem to get it to go below 20. If I go below 20 it reverts to 100.

Leave it at 100 - dropping it down hurts more than helps...

Unless you have areas with really weak coverage and lots of interferences, but where you have no other means to create good coverage, don't decrease that value. For devices within a good coverage you don't need everyone to shut up to hear a beacon. It uses air-time, it's send to the basic speed and it competes with clients traffic. It hurts all devices under good coverage! Ideally you should dial it up to 200ms or so, rather then dial it down to 50 or lower...
