  • 1.  11D Ethernet speed

    Posted 03-10-2022 05:45 AM
    Today I suddenly found that the AP11d ethernet port speed can not exceed 500Mbps under Intranet.

    The speed of the ap uplink can reach 900mbps.
    This is not a joke?

    Hi Eisen,

    I'm working with my team internally about your concerns. Also, can you provide us with the topology?

    Confirmed issue here as well. Interesting.... thanks for discovering this, @eisen! 

    **UPDATE: This is not only affecting the 11D hardwired ports, it's affecting all transmissions through APs. Cannot hit above 500Mbps, even when MCS Rate is at 9 w/2 Spatial Streams (theoretical Max of 866Mbps)**

    Hardwired to AP11D:
    - UDP tests result in full 1Gbps transfer
    - TCP tests max out at approximately 472 Mbps​

    Hardwired to 1930 24G PoE Switch:
    - Directly hardwired to 1930 24G switch yields ~940 Mbps

    - This test network is flat, w/no restrictions or shaping
    - AP12, AP11, AP11D, 1930 24G POE
    - Tested via '21 MacBook Pro & '14 MacMini

    Hi Ethan
    Wow, Thank you for your information. I have a very good SNR but can't negotiate to 867mbps(MCS 6) use my MacBook Pro; there was no problem before, so I switched to cable, and the result was even worse.

    I'm also seeing slower speeds than advertised.

    Thanks, JM78.

    I should be available to troubleshoot w/support if required. 

    Appreciate your help. 🙂

    @JM52; Are there any updates on this case?

    We are facing same issue with a partner and an even worse case because on uplink connection doesn't hit 500Mbps​​.

    Btw, @The WiFi Guys; can you share which software tool are you using to test it?

    Thank you.​​​

    Hey Iker,

    I want to confirm that I don't have a formal update for you. Unfortunately, there's no solution I can provide, but once I know more, I'll update the thread.
