Authentication Failure - 1 Client - Guest SSID with NO Encryption.

Nick C. — Mon, 05 Jul 2021 16:45:42 GMT

After factory resetting my phone (Samsung S8) stopped connecting to WIFI in the area I sit. So far everyone else (except for 1 other samsung user) is able to connect. This has been working for 3+ yrs, and no changes to the WLC or AP's. I can walk around my building and hit 20+ other AP's Guest SSID with no issue, soon as I return to my desk the connection will just drop, even with good signal. My phone will say Authentication Failure, sometimes after 20+ tries it will connect, but just briefly before being kicked off.

Can someone please help with the debug? I think this is the part of the debug where I'm dis-associated.

Could be a software bug on the WLC you are hitting, which version are you running?
Your debug output looks ok, can you run it a bit longer (debug client a0:cc:2b:08:96:31)? Including an authentication retry.

Rebooting the AP fixed the issue. Probably a bug related to the iOS version. Thanks for the help!
