I’ve got problem with one wireless, it is working fast enough, but when working little it stops and cannot connect to the ap again. miniPCI card is CM9. Software is Mikrotik 2.9.6, and the oposite side is the same …

I had problems with the exact “deauth: class 2 frame recieved error”

Mikrotik - Still would like to know what this error means..


This would happen when we loaded the link. Switched channels and the errors and disconnects went away. Might be interference. Try a different channel if you haven’t already. I would also upgrade to the latest release 2.9.8

MT 2.9.6 is not stable if you are using 2.4 ghz .. I’ve had the same problem and my prism2 card got burned cuz of a storm..
now i’m using MT 2.8.26 and it work fine I dont’ get users disconnected and data loss ofcoure changed the prism2 card.

ps. talking about 2.4 ghz .. MT 2.9.6 works perfect in 5ghz

CM9 is 5 GHz.

I’ve change the frequence but I hadn’t chance to make some traffic weekends. I’m worried about too interrupts in work:

I’ve changed the frequence and everything now works fine.
I’ve got a tower with 3 wireless cards set to ap-bridge and 3 remote mikrotiks. One week after this issue the other 2 cards got the same poblem, and I use the same way to repair them (changing the freq.).
Cards are new from box (they were working for 1 month).
But now i’ve got another problem I’m not sure is the reason the same (I’ve start another thread).
