Dennis, Have you tested your Android devices with FT disabled? (instead of FT Adaptive). I would be curious to hear what results you get.
Thanks, Hector Rios, Wireless Network Architect The University of Texas at Austin From: The EDUCAUSE Wireless Issues Community Group Listserv <WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> On Behalf Of Dennis Xu Sent: Friday, June 26, 2020 11:45 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] WLC 8.10.121 Deferred We have upgraded to 8.10.121.0 for one month. We have seen some devices not able to connect. When they run into this issue, we don’t see any association requests from the devices. There are something in the beacon which are not liked by the devices so they do not want to join. Not a lot of devices affected, mainly from Android 10 devices(from MI, Huawei and Nokia vendors). I also have two Windows 10 laptops having similar issue but they were able to connect after a wireless driver upgrade. We only have WPA2 checked for WLAN security. I opened a TAC case. The only workaround for Android 10 is to set FT to enable instead of Adaptive, but I did not accept that as I am afraid it will cause bigger problem for other devices. My TAC engineer said Cisco is working on a fix for this issue and ETA of the release is in July.

We are currently on 8.10.121 and seeing this issue as well primarily with Windows devices. I have not seen any issues with Macs and authentication.

It is weird because radius isn't even seeing the attempts (or weren't logging rejections). The behavior persists even using local authentication. Eventually we can get the clients to connect, but it takes a number of attempts. It's very frustrating. Cisco had us upgrade to 8.10.122, but the problem still persists. We would roll back, but we have 9130's on the campus now and we need 8.10.122 to manage them. Such a headache right now.
