Hello, I have a client issue with a user. He dissconnects very often and a radio trace and clientinfo shows this:

Any suggestions what to check ?

 - Looking at the radioactive trace it seem that the AP 'was full' and no longer accepting new clients ; also have a checkup of the WLC-9800-40 controller configuration with the CLI command : show tech wireless ; feed the output into 
                                                       https://cway.cisco.com/wireless-config-analyzer/

 If this happens in a crowded area you may need to review the RF design and or add AP's (e.g)

As @marce1000 said, the AP has reached the maximum number of clients per radio/wlan that is configured so 1) increase that number or 2) add new APs.

Take care with increasing the maximun number of connected clients to a radio as that could lead to issues due to RF congestion like packet drops and disconnections again.

@marce1000 and @JPavonM 
Thank you for your fast reply.
It seems like it is only this iphone client that have problem, other users can connect to the AP.
