Too many "group key timeout" when using CAPSMAN

RouterOS General
1

I’m using CAPSMAN to provide wifi access. However, many iOS and Android devices disconnect very frequently with “group key timeout” in RouterOS log.
For legacy wireless ap, I can change group-key-update time to a longer one, but there isn’t any way to change it in CAPSMAN.
Any solution?

From the v6.38 changelog:
*) capsman - added “group-key-update” parameter;

You have to go to the terminal command line to change it or display the current value. “capsman security group-key-update”

Please add this to WinBox?

Thanks,

Hello. I’ve set group-key-update to 55 minutes. Also it’s stated in manual that default value is 5 minues, so I can’t get how this can be:

16:22:20 caps,info 28:CF:E9:01:2D:59@cap-MikroTik ST-hAP-AC-Lite1-1-1 connected, signal strength -50
16:22:24 dhcp,info mySSID deassigned 192.168.66.230 from 28:CF:E9:01:2D:59
16:23:50 dhcp,info mySSID assigned 192.168.66.230 to 28:CF:E9:01:2D:59
16:24:38 caps,info 28:CF:E9:01:2D:59@cap-MikroTik ST-hAP-AC-Lite1-1-1 disconnected, group key timeout

As you can see it’s timed out two minutes after the connection established, also it had a good signal and got an IP via DHCP. Is there another timeout in key exchange that is out of our control?
