Connection with WLAN, but no DHCP request work after removing an AP from config

Connection with WLAN, but no DHCP request work after removing an AP from config. I think it is the the same problem like adding an AP in the previous version. It is only with networks that use separate zones. When I reboot the ASG all work fine.
