After upgrading my C9800-80 controller from version 17.12.4 to 17.12.6a, some access points remain stuck in the “Downloading” state. The following logs are present on the access points. Feb 6 00:15:58 kernel: [*02/06/2026 03:15:58.5390] CAPWAP State:...

After upgrading the C9800-80 WLC from version 17.9.6 to 17.12.4, access points of models 1700, 2700, and 3700 reverted to their default configuration, including hostname and tags. What could have caused this behavior?

Probably your problem resolved but main reasan that is in a of clie output. Multiple policy profile AVC settings associated with this WLAN. Wlan profile - policy profile map match at tag assingments not uniqie.
Thanks for reply. Actually, as you mentioned, it is reasonable to consider the install all method as the recommended approach since it performs prechecks. However, for some reason, when I run install all, I get the impression that not all chassis wil...
Approximately 100 model 1702 access points experienced this issue, and there was no hostname conflict that could have caused a problem. In fact, the reason I opened this post was to see if others had experienced the same thing—so I could determine wh...
