Devices wireless adapters getting disabled after 3 failed attempts

[jjtech]

Hi,

We're facing an issue with clients PCs wireless adapter getting disabled each time their device tries to connect to our Cisco APs for 3 or 4 times in a row and it fails (either due to an internal connectivity issue or aaa authentication failure ...).

This behavior is only appearing for the devices connected to our Cisco APs (mostly AIR-AP1832I) running 8.3.150.0 registered on WLC 5500 version 8.3.150.0 

To summarize, the users who try to connect to our APs while we have a network issue are getting their wireless adapters disabled.

Have you heard about this behavior before, or any idea what might be triggering this PC adapter behavior?

P.S: The client devices affected are of different models (running Windows OS)

Client Exclusion Policies

I agree with Leo here as “if you can’t remediate network issues”, then you are best of disabling this. Any loss of connectivity to your AAA or issues with your AAA servers will exclude the device(s). If you have a stable network, then client exclusion works well.

  - For starters these controllers are getting very old you don't mention the exact model 5508 or 5520
    As per https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/200046-tac-recommended-aireos.html
                  (and also the software version is too old)
   For the 5520   8.10.196.0 should be used    and for the 5508 https://software.cisco.com/download/specialrelease/9a6a7cf84f9fdf04b95c76e2ac7820e7

   This is becoming important these days if modern devices are coming on the network and to have latest bugfixes because aireos is being phased out and effective support by Cisco is no longer done ,

   - You can also have a checkup of  an aireos based controller's configuration using :
     WirelessAnalyzer input (procedure) for AireOs controllers
                   and copy the output from that into Wireless Config Analyzer

   + You can also troubleshoot clients using : https://www.cisco.com/c/en/us/support/docs/wireless/wireless-lan-controller-software/213258-collect-debugs-from-wireless-lan-control.html
     Client debugs can be processed with : Wireless Debug Analyzer

   + Added : and for authenticating checks ; check logging on radius servers and look into stuff like Cisco ISE live logging if used
                  
  + Adding : also make sure that the client wifi drivers are up to date

Thank you for the suggestions. I will proceed with moving the affected access points to another WLC 9800 having newer AP images and will confirm back if the issue is solved on the new version
