Hi Everyone -
I have a 4402 controller with one SSID on it. Currently, it's set for Web-Auth. It was running version 188.8.131.52 with no problem but last night I upgraded to 184.108.40.206 in order to correct the wildcard certificate problem.
When the upgrade finished and my AP's registered, web auth stopped working. Clients would associate to my SSID, and receive a DHCP response. But when they launched their browser, the URL bar indicated that the redirect was attempted, but I got a "This page cannot be displayed" error.
When I tried to downgrade the controller back to version 220.127.116.11, the WebUI and CLI "show sysinfo" still indicate version 6.0, even though "show boot" shows that the 18.104.22.168 image is now "Active".
Any help you could provide would be greatly appreciated.
