I'm running AirOS V5.2.1-RC2 (which is the latest as of yesterday) It happened with the factory firmware and the RC1 as well.
The issue also occurs with my laptop running btest or any type of ping flood. I have 6 cat5 runs up one of the towers, Motorola works fine and I have switched cables, different manufacturer as well. Same issue. When I use the air test from the UBNT device it works fine. When I plug a laptop in on each side, I get the same results. No bandwidth shaping. Have tried multiple different devices on each side, the only thing that works is an expensive Managed Dell Switch.
