Last disassociation reason- "Proprietary failure"

awatson20 · ‎10-08-2019

We have ipads that will stop communicating at random times on a WPA2/PSK WLAN on a 5520 with 2802i access points, operating on software code 8.5.135.0. We see this error message. I have not been able to determine what this means, and Cisco has not been able to give a good explanation. I have attached a screenshot. Has anyone on here seen this? Thanks.

I saw this bug, but not much information on it or if 8.5.135.0 is affected.

1. Raise a TAC Case. I agree with Marce and I believe this is CSCvg14346.
2. I've used 8.5.135.0 before and I'll never recommend anyone use that version.

We are in the process of upgrading to 8.5.151.0. Thank you.

- Consider the worst-case-scenario in that case. But note also that apparently this is not a Cisco bug ; but apparently an Apple bug.
