    Is there anything I can do on the Aruba AP for more seamless roaming of WIFI access, when users switch AP1 to AP2 nearby?
    currently when user switch to different AP, they will noticed a drop in WIFI connection.

    How far are those APs away from each other?
    What are you using? Controllerless or controllerbased WiFi?
    Have you turned ClientMatch on?

    See the following Document for additional suggestions - https://community.arubanetworks.com/browse/articles/blogviewer?blogkey=9b71b25a-80a1-4851-8b5f-21fdc9ab083f

    APs are about 5 metres apart.
    AP-303. we are using Aruba Central to managed the APs.
    Can I turn on ClientMatch if I am using Aruba Central ?

    Yes you can, when you are on 6.x or 8.x

    What is the Roaming Dashboard of the Client saying? Do you see high latency Roaming?

    Any AI Insights regarding Client Roaming?
    What type of clients are having issues?

    What Software Version are you using?
    Did you enable 802.11r/k/v? - in my experience some Clients have issues with activated 802.11r, so if enabled, disable it for testing.
    How are Clients authenticating?

    Output of 
    show ap neighbors
    show ap arm history
    show clients
    would be nice to see

    From you screenshot I can see that ClientMatch is disabled. You should enable this without changing the Default Parameters.
    You will find the Roaming experience in the Client Details View at the bottom.

    802.11r will be enabled / disabled in the WLAN Settings of the SSID on Security Tab.

    Your Screenshot of AI Insight is not really helpful. You can´t see the numbers of Radar detection, Errors, etc.

    CLI Output of
    show ap neighbors
    show ap arm history
    show clients
    would be nice to see

    You also can open a TAC Case.
