    Hi everyone.

    I want to know how to avoid the errors on IAP-103

    Some users seem to have problems with connection. Low speed, etc.

    Aruba Central graph shows errors on 5GHz channel:

    RF channel utilization

    The other graphs don't seem to be useful.

    What is the critical error level?

    What is the nature of this errors?

    How can I avoid them?

    Simple Instant cluster without controller: IAP-103, 105, 205

    This graphs are from IAP-103

    It is located in the office room.

    ~10 5GHz clients

    ~10 2.4 GHz clients

    Devices: iphone, ipad, macbook air, macbook pro

    The 5GHz range is not very busy: 3 IAPs and 1 asus router there.

    2 ssid's: for notebooks and for mobile devices.

    I've found that all of IAPs had error peak at the same time on the August 5th.

    All ranges were affected. How to diagnose this problem?

    Hmm. The situation is strange.

    The wireless clients graph shows that it was ~400 clients at the peak moment. But I don't really think it was. There was aruba central disconnect at that time. Maybe it's just a bug?

    And what's the difference between clients and wireless clients?
