  • 1.  Issue with Aruba AP Performance

    Posted Oct 23, 2025 06:36 AM

    Hi community,

    I'm experiencing performance issues with my Aruba AP-515 (running ArubaOS 10.4) and would appreciate any advice.

    Problem:

    • Random disconnections for wireless clients (~5-10/day)
    • High latency spikes during video calls, despite strong signal
    • Only affects the 5GHz band; 2.4GHz works fine

    Current setup:

    • Single AP-515, 20+ clients (mix of laptops/phones)
    • WPA3-Enterprise authentication
    • Airtime Fairness and Band Steering enabled

    Tried rebooting and channel adjustments, but the issue persists. Any known bugs in 10.4? Should I try a downgrade?

    Do you have just a single AP? In that case, try to force it to the low channels (36-48) only which don't have DFS enabled. Also reduce the channel width to 20 or 40 MHz. If you are on a high channel and radar is detected, the AP has to terminate it's transmissions (legal requirement). With larger channel-width, chances are higher that you have that issue.

    Also make sure you are on the latest, or at least the Central Recommended firmware release; I think there have been resolved issues in earlier 10.4 releases.

    What you see can be many things, including other networks or interference around you. It may be good to work with your partner to check configuration and insights/logs that Central may provide to improve the performance.

    the recommended firmware for 10.4 is 10.4.1.10 and looking at the release notes there are quite a few connectivity issues with AP-515 that were resolved.
