    What version of ArubaOS?

    What kind of client device is this?

    What kind of encryption are you using?

    This message is something that occurs:

     

    - When there is a certain level of interference

    - When the driver on a device is not up to date

     

     

    It could be either of the two or a combination of the two reasons.

     

    I would also say to limit your SSID only to a single type of encryption, not two.
