IW3702, 8.5.151.0 - FlexConnect mode - %DOT11-5-EXPECTED_RADIO_RESET

Hello

I noticed a radio issue with IW3702 APs running version 8.5.140.0 and FC mode. Looking at the logs on the APs I noticed a bunch of radio reset codes similar to those below. I did some searching online and I found a bug with the same issue for a different model AP and mode described here CSCvn56211. So I upgraded APs to the suggested version 8.5.151.0 however, the issue still remains.

Does anyone have a similar issue?

Might be a bug. If I read you correct, it happens to more than one AP, right?
If yes, then I suggest you open a TAC.

rudimocnik · ‎09-02-2019

Yeah multiple APs. I opened TAC issue. Waiting.

Ok, please keep us updated here too, would be great to read the solution.

Did you get any resolution on this? I'm in the progress of migrating a bunch of 3702's running 8.5.151.0 from local to FlexConnect mode and have started noticing these errors popping up in the logs.

Is there a reason why you don't upgrade to the newer 8.5.x builds?

I also found this bug, which is not exactly the same, but might be close enough:

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvn53435

That one is fixed in the 8.5.160.0 release, but there are also other radio bugs that were fixed in the newer builds.
