AP Problem after upgrade to 2.9 rc4

RouterOS General
1

Hello

we upgraded one RB230 with 4 AR5213 boards tu 2.9 RC4 and then only about 70% of the clients connected permanently to the ap - some the others just showed up für few seconds and then disappeared .
also the numer af connected clients changes permanently by about 20 users.
after playing around for a few hours i downgraded again and ally my users where connected again ( about 75 users)
what has changed or is there anything to change in the config ?

has anybody an idea ?
regards

Next time when you upgrade your routers to v2.9 and you are having such issues, please make the support output file and send it to the support@mikrotik.com with a description of your router, so we could try to figure out where could be the problem.
