Controller IP: 10.102.220.200. APs: 10.102.220.20-24.
If I try to go to 10.102.220.200, I receive a timeout browser message.
If I go to 10.102.220.20, for example, I am redirected to the IP of the AP that is listed as "Master."
So if AP 10.102.220.23 is "Master," when I go to 10.102.220.20, 21, 22 or 24, I am redirected to 10.102.220.23. If I reboot 23 and 21 becomes "Master," then I am always redirected to 21 any time I try to access one of the APs directly through the web GUI.
