WLAN CONSTANTLY DISCONNECTING CLIENTS

My WLAN clients are experiancing instable network connection. They are disconnected from the network and sometimes they have to manually reconnect or sometimes even disable and re-enable the Wireless Interface before it reconnects to the network. I therefore debugged some of the clients and attached is some of the debug results. Can someone explain what is wrong from the debug attached:

 

Thanks in advance:

Hi cjoseph,

 

Thanks for the quick response. I have Aruber AP-135s deployed with OmniAccess4504XM controller. This problem started about 2 weeks ago. Most of the clients are windows clients with some few Mac clients as well. I am using "wpa2-psk-aes" encryption.

 

Thanks and standing by for your response.

Re: WLAN CONSTANTLY DISCONNECTING CLIENTS

How many access points do you have?
Do the wireless clients share a vlan with wired clients?

There are 32 AP-135s deployed. The internal clients are on the management VLAN 1 and guest clients are on VLAN 32. These VLANS are used by just the WLAN clients and do not share with the wired clients.

Do you have "drop broadcast and unknown multicast" enabled on all of your virtual APS?
