After upgrade to 3.30 clients disconnecting

I’ve upgraded Mikrotik form 2.9.51 to 3.30. As my plan is to upgrade to 4.5, I installed wireless-test package.

Now some of wireless clients are disconnecting from AP. Clients are running factory made wireless client bridges, not Mikrotik. I do not use nstreme.

Log shows this:

wlan: 00:31:4F:4A:54:53 attempts to associate
00:31:4F:4A:54:53@wlan: reassociating
00:31:4F:4A:54:53@wlan: disconnected, ok
wlan: 00:31:4F:4A:54:53 in local ACL, accept
00:31:4F:4A:54:53@wlan: connected

And this goes again and again and again… every 10 to 20 seconds.

I did try reset-configuration and setting hardware-retries to 15. It did not help.

When I disable wireless-test package and use wireless package, than this problem disappears.

As I said, my plan is to upgrade to 4.5, and as I understood, I would have the same problem, because wireless-test package from 3.30 is wireless package into 4.5.

What should I try to do to make this work? I searched the forum, but all I find are complaints about this problem without proper solution.

Contact support!
Make supout.rif file and send it to support@mikrotik.com along with your problem.
And hope tha MT team could reproduce those problems.
