AP continue showing the network in absence of controller but wireless stations are not getting IP address from DHCP server.
Can anyone suggest the best practice for same as we are doing POC for one of the hotel chain and they want to test, if the links goes down between DC and hotel the AP should function normal.
Yes. The latest version of 9.21 is good. Also ssh to the AP with username admin password new2day. Run this command. tail -f /tmp/log/ap.log Then reboot the controller. This will show you what the AP is doing from its perspective and might help.
