    Hi everyone. I am facing an issue . Some APs are only giving 2.4 ghz and only 72 mbps connection speed. While the same will connect to other APs at 5 ghz. All APs are in same Ap group. 80 mhz is enabled. What can be the issue.

    Hi Muhammad. What AP model(s) are you using? How did you determine that 5GHz is disabled on some APs? Does the Aruba management UI confirm that? What are the client devices you're testing with?

    We are using 515 and 345. I can verify by "show user-table" for client association. I have tested with different devices,iphone , laptop.

    It's ultimately the client device that decides what AP and radio to connect to. The 2.4GHz signal may be much stronger and the client may decide it prefers that. Do you have any clear indication that the AP is indeed not transmitting on 5GHz? Does that happen both on 515s and 345s? Have you tried creating a 5GHz-only SSID to see if the client can connect (and remains connected) to that?
    72Mbps on 2.4GHz (20MHz bandwidth) makes me believe that this is a 1x1 11n/ac client (or a 2x2 one operating with 1SS)

    When i enable only 5ghz (a) the problematic AP doesnt transmit ssid at all. What should be the next step

    First, try to assign channel 36 for 5GHz and scan again.
    Second, power is enough for the device no amber light on status, right?
    Else, create a ticket for technical support.

    Agreed. You may have a hardware issue on the 5GHz radio(s).
