Hi

 In this situation, I´d consider fallback to the older version or try a different version. You may hit a bug.  Unless you are looking for a feature that only exist on the new version, I´d prefer keep my devices on the versrion they work fine.

I also saw error of bug, then i thought to take suggestion from experts. can you suggest good way to resolve the issue without network interrupt.

[Rich R]

If you must go to 8.10 then I'd recommend 8.10.171.0

https://software.cisco.com/download/home/286285803/type/286289839/release/8.10.171.0

It's already the suggested release for WLC - I think they just haven't got round to updating it for ME yet.

Otherwise like Flavio said you'll have to consider rollback.

There is no option to fix this without some disruption unfortunately, and the workaround on that bug is to reload the AP.

[lalitkumar88551]

Hi rrudling,

i had upgrade to 8.10.162.0 but nothing change same issue still associate & disassociate from WLC & it is continue try to join & then few minutes later again disconnect & again join.

reload one AP and see if this will fix your issue.

[lalitkumar88551]

Hi MHM,

already try to  reboot  one AP and see the issue not resolved  & I also upgraded 8.10.162.0 but issue is same.  

[Rich R]

Like I already said if you're going to upgrade then you should try 8.10.171.0 not 8.10.162.0

[Paolo Moserle]

Hi, same issue with ME on 8.10.182.0, someone was fixed it ? tnx

[Rich R]

This thread is quite old now!
Your first action should be to update to latest release as per TAC recommended below - currently 8.10.185.0 - to eliminate any known bugs which have been fixed.

If you still see the problem after upgrade then best to open a new thread with complete details of the problem you're seeing and the troubleshooting you have done.
Also provide details of AP model(s) and software version and any relevant logs from AP and/or ME.
