re-authentication during use after upgrade to 17.15.0.3

id404 — Fri, 20 Jun 2025 02:06:47 GMT

Since upgrading my Cisco C9800-40 Wireless Controller to 17.15.0.3, the wireless guest authentication will ask for re-authentication during use, which is very disruptive to the user. Also the wireless guest authentication is using CWA method to interface with Cisco's ISE. is there any way to troubleshoot this issue.

Did you at least run a diff using the previous configuration file vs the configuration after the upgrade? If you have problems after the upgrade, you should revert back. I see soo many folks that just make a change, cause some sort of outage and then try to remediate the issue causing user experience issues.
