Does anyone know the work around for this?
I can install any V7.x.x image and the AP works fine, install any 8.x.x image and the AP goes into the boot loop failing on the Radio FW Image download.
Tried updating the image via Rmon, is there a version I need to install to get this AP working with V8.2.151
What controller firmware version are you using? I am very familiar with this bug.
There are two ways of fixing this:
1. Force the AP to boot the RCV image by deleting the CAPWAP image.
2. Force the AP to boot into ROMmon, format the flash, and upload the RCV image.
In both methods, console access is the only way.
These are the methods I've developed myself because I was encountering this bug when I would "loose" an AP every three days.
I've upgraded my controller to 18.104.22.168 and this issue has stopped.
Issue is present in 22.214.171.124/126.96.36.199.
Cisco will be publishing new firmwares to fix KRACK WPA2 vulnerability. I recommend you go with this fix.
Fix firmware are scheduled for release on 23 October 2017 (see image below).
Im looking forward to hearing if the newest 8.3 solved the problem. :-)
We have multible 2700 that does this as well.
A hardreset of the AP (holding down the reset button) is the easy fix for us at this point.
188.8.131.52 still getting a problem with 1x 3702 however I have fixed about 8x 1702 by formating flash and using recovery image.
Had about 40 APs fail in a boot loop with error like below
%CAPWAP-3-ERRORLOG: Validate Msg: msg type 4 does not supported payload 215
%LWAPP-3-CLIENTERRORLOG: Validate Msg: msg type 4 does not supported payload 215
%LWAPP-3-CLIENTERRORLOG: Validate Msg: error in unknown payload (received length = 9, payload type = 215)
%CAPWAP-3-ERRORLOG: Failed to validate vendor specific message element type 215 len 9.
%CAPWAP-3-ERRORLOG: Config status: Failed to validate vendor specific message element.
%CAPWAP-3-ERRORLOG: Failed to decode join response.
Able to fix them remotely by forcing them to an 8.2 version on another controller by using a vlan that has an ACL blocking the 8.3 controller IP. Then once they have downloaded 8.2, change vlan back to normal put them back to 8.3 and they work okay.
I have lost confidence with doing software updates as imagine having to console when you have 1000 APs in a hospital!

No, this issue is totally different.
Break into ROMMON and post the complete output to the command "dir flash:".

I received the same error by trying to boot that.
I fixed the issue by formating flash: and following this guide.
