My controller 2400 (ip address is 10.10.10.10) is dhcp server and send ip address to my AP-61, and my AP-61 is able to get ip address from controller, let say my AP-61 ip address is 192.168.10.1 /24 (get from dhcp), then i change it manually to ip address 192.168.20.1 (branch ip address range), change the host master controller ip to 10.10.10.10, apply and reboot the AP. After that i move the AP to branch site, there is no controller at brance site. From the branch, ip address range 192.168.20.0 /24 is able to ping my controller ip 10.10.10.10, but once i connect the AP above to brance switch, AP not able to find controller. So should i reset my AP configuration then set static ip address for the AP since dhcp server at brance site without connect directly to the controller?
