RB532 issue with ROS 5.0xRC

Facing some wierd issue with RB532 + Compex WLM54AGP A6 (Atheros AR5413) cards. Now running ROS 4.13 and have no problem. But with ROS 5.05RC get very high packet loss and disconnecting form AP.. :open_mouth: No differece 2.4Ghz or 5Ghz, same on both cards.

P.S. FW up to date (2.18)

all problems are fixed in the latest releases. I had issues with earlier version.
