    Hi all,

     

    I need some help here.

     

    Some clients that connect to AP has suddenly disconnected by itself.

    It happened on random devices at random times.

     

    When i tried to check the log using 'show ap client trail-info' command on devices that disconnected, the log show this info 'wlan driver excessive tx fail quick kickout'.

     

    Standalone Controller: Aruba 7210 with os version 8.6.0.2

    AP: 305 and 315

     

    Any ideas what causes these?

    If max-tx-fail retries value is reached, then the client will be deauthed from the AP. But like everyone has been saying, I would open a TAC case.

    Is this issue fixed ? We experience the same with quite a lot of AP-315's (about 1/4 of our installed base) on AOS version 8.6.0.5 currently and having an uptime of around 40 days.

    After an apboot, the issue is gone for a while.

    we fixed this issue by downgrade the os to version 8.5.0.10

    on excessive retries, the AP deauths the client.

    8.6 build onwards, in this case you should see the error :" Wlan driver excessive tx fail quick kickout". 

    Previously, you would have seen the error:  "Denied: AP Ageout".  


    investigating the excessive retries by doing air captures would be required for further analysis
