First off thanks to everyone as lurking in this forum has helped me greatly over the last couple of years.
I am currently having issues with a 433AH (Atheros AR5413, version 4.11) in ap-bridge mode servicing 10 Ubiquiti PS2 clients. The PS2’s will stay associated for about 20 minutes, and the wireless stats, rates, and CCQ look very good. Then they will all disappear from the registration table due to a “class 3 frame received (7)”. The only thing that brings them back is a channel change, and 15-30 minutes later it happens again.
In testing from the client side you can see that the PS2’s are staying associated while absent from the registration table. They maintain a wireless connection, but lose the ability to ping the AP. I’ve tried spectrum analyzing from both ends, and isolating each client, and see nothing that would cause this behavior. There is another MikroTik 90 degree sector operating about 3’ away that is working perfectly. We operate 60+ deployments like this one and I’ve never seen anything like it.
It seems like the AP is losing it’s receive side without sending a deauth to the clients and the PS2’s are still transmitting data, resulting in the class 3 frames. Anybody have any ideas?
Below is a sample config, thanks for the help.
