Wireless Statistics show a lot of Errors and Failures

    Hello,

    I need some help interpreting the output of the Wireless Statistics.
    We see a lot of generic "Errors" "ACK Failure" "Retry Count" and I have no clue, what could cause them. In general the clients have connectivity to the Wifi but sometimes they don´t get any data across the link. We see that they sometimes have a loss when doing a ping. I´m not quite shure where to start here.

    Thanks in advance!

    Hi Paul.

    could you please provide the controller model, AP model, software version.
    If you click on the AP in the AP overview you get the window with the client/noise,/channel util - could you please post a screenshot of it for this AP.

    -Ron

    And the screenshot please - that could sometimes tell you a lot.
    Here a very bad example, channel util on radio 1 on max which could result in a lot of errors.

    Hi Paul,

    There is a "Channel Inspector" in Reports, could you please take a look over there?
    If the AP is not loaded with clients, it might be due to amount of SSIDs or other interferences on the same channel or adjacent ones. This could be another thing to look at.

    Kind regards,
    Tomasz
