I have searched this forum for this topic, but havn’t seen anything conclusive.
I have 1 RB600A running ROS 3.28 with Atheros AR5413 with 5 clients running Ubiquiti NS5/PS5 with WPA2, and 1 RB532A running ROS 3.28 with Atheros AR5413 serving 3 Ubiquiti NS5 with WPA2. These units are mounted together and are interconnected via a cable between the two.
Apprx once every day one, two or all three clients on the RB532A simultaneously get disconnected with the logmessage ‘Unicast Key Exchange Timeout’ and get reconnected after a couple of moments.
The clients on the RB600A never get disconnected.
Is this a known problem or do I have a defect wireless card?
