Hello!
I use AR5212 802.11abg NIC (rev: 1) on RB532 (OS v. 2.9.27) and from some time still have such messages in logs:
“disconnected, decided to deauth: 4-way handshake timeout (15)”
This behaviour became common and very persistent in the system. There are generated those messages for the most of users’ wireless devices (about 300 clients).
Could anybody explain me what is a reason of those renegotiations messages?
Regards, Marek

So as you can notice in the system is a quite wide range of wireless devices available in the market.
As an additional information: system consists of about 50 hotspots based on Mikrotik platform.
I will forward this message to MT support as you advised.

this must not be a router problem but on the client side.
i have Fujitsu-siemens build centrino laptop M3438G (wich is faulty) and have the same problem, while my wife with fujitsu-siemens laptop, but with broadcom wirless card have no problems at all.
hello,
we have the same problems since about 2 Weeks…
Therefore we had no problems, but no it´s comming up on different RB500 boards!
We changed nothing on client side…
802.11 b/g with WPA AES encryption
How could this be?
This is a big problem for us, because about 30% of our clients could not connect at the moment!
pls help!
I forwarded description of this issue to MikroTik Support but still have no reply.
Regards, Marek
