    Hi All

    There is  Aruba 650 controller and AP's (105,125,205). On 125 model AP, client connection problem appear. I take some logs (attached). What can be root cause of issue ?

    - What version of ArubaOS is this?

    - It looks like you are running 80mhz channels on the AP205.  It is best that you use either 20 mhz or 40 mhz channels, instead

    - How many access points do you have?

    - Do you have drop broadcast and unknown multicast enabled on your Virtual APs?

    From your logs, it seems like you might have multiple system issues.  I would open a case with TAC so that they can review your logs.tar and identify all of your issues.
