On Tuesday, I upgraded WCS and 7 WLC 4404 from version 220.127.116.11 to 18.104.22.168. Since then about 250 1131 access points have not come up. I reloaded the configs to all of the controllers from the backup that I did before the upgrade, but they still didnt come up. Does anyone have any ideas?
edit: I forgot to mention that my access points are set up with static IP and are spreadout through controllers 2-6 and use controller 1 as a backup.
