  • 1.  Aruba AP-515 not broadcasting 5Ghz

    Posted May 26, 2024 04:58 PM

    Hi 

    I have an issue where a connected 5ghz devices keep connecting to 5g ssid but once a new device came to connect it cannot connect to 5hz network and only 2.4g is connecting. The only work around I found for this issue is to shut and restart the port from the network switch which restart the access point and I can connect new devices. Kindly help me with this issue. 

    We use Aruba controller 7030 with version OS 8.10.0.8 LSR 

    AP-515

    connected to cisco c2960x access switch 

    Thanks 

    Mustafa

    Hi Mustafa,

    first of all it is the decission by the Client to which band it is connected. Are those new Clients dual Band clients?
    Is Band Steering / Steering Mode enabled?

    Can you give an output of 
    show ap bss-table ap-name <APNAME>
    show wlan virtual-ap <PROFILENAME>

    Hi Cordless, 

    Sorry for the late reply I was out of office for couple of days. Here is what you requested :

    The device I'm looking for is not connecting to this AP even though the device is setup to be connected only to 5hz and the in the same room. Actually the device is connecting to another AP far away.

    Is there a possibility the issue from the OS ver ?

    For more instant responses, please open a TAC case.

    I see channel 157E assigned, which may not be compatible with some devices. You may also have set a client limit per AP, but I believe minimum value is 32 clients per AP, which does not explain this on a close-to-empty AP. TAC may be able to check your logs and see what makes clients not connect.

    Upgrading to a recent firmware version in general doesn't hurt, but it's just a lucky shot. TAC may suggest to upgrade to a recent version as it fixes other thing and rules out a few things.

    Hi Herman, 

    Thanks for your reply, I will review our options for upgrading as just recently upgraded to 8.10.0.0.8 LSR. 

    and I see our only option now is to open TAC case. 

    Appreciate your support.

    You might want to get that version of code up to 8.10.0.11LSR (mind the firewall opps as well); the reason is that there are a mass load of bug-fixes and kernel crash issues with 8.10.0.7LSR and 8.10.0.8LSR.  Check out the release notes; I think that I counted 16 bug fixes with that one model of AP alone.

    I will check the release notes thanks for the heads up. for the mean time we still facing this issue.

    Would be interesting to get the mgmt-frames output when the second device is trying to connect to the AP.

    #show ap remote debug mgmt-frames ap-name AP15-5044

    This will give us some more details whether the device tried to connect to 5 GHz but was denied by the AP

    Hi Sajinnair, 

    I have opened a TAC support with Aruba and will start troublshooting this issue to find out the logs and solve this issue.
