Group key timeout - Disconnected

Hi Everyone,
Recently, I bought a couple of cAP ac and deployed CAPsMan on my router. But I often encounter the WiFi drop out on my iPhone and laptop. I checked the log and it shows " group key timeout".
Once WiFi dropped out, sometiems, my iphone somehow doesn’t automatically re-connect and will use LTE instead, until manually re-connect it. Sometimes, it re-connect to the AP immediately.

Anyone else had same issues ? And how to solve it ?

Thank you!

I have the same problem.

Under 6.42.2 or 6.43.X I sometimes can’t even reconnect any more with any of the devices.

Under Firmware 6.41.X or 6.40.8 I still get the timeouts, but at least I can reconnect.

Submitted a file to the support. Gonna keep you updated.


Would be cool to just use one thread for the same issue, so people rather notice, there is something wrong.

What firmware are you running tho?

6.42.2 now, the previous version I had same issue.

Please keep me posted if you get any reply from mikrotik support. Thank you !

@Kerbia, any update from the support team at MikroTik ?

I have the same problem with Capsman + cAP ac devices. The Capsman manager runs on an RB1100AHx4 dude edition. I have tried already 6.42.7, 6.43.2, 6.43.4 ROS versions, but the problem still exists. Do you have any solution or workaround, that can eliminate or at least decrease this annoying phenomenon?
