    - What is the output of "show ap active" or "show aps"?

    - Do you have broadcast filtering enabled?

    - What wireless client are youusing for your tests?

    You have 40 and 80 mhz channels enabled which will cause alot of contention.  In the RF ARM profile, make sure that 80mhz channels is unchecked.

    Hi Cjoseph , 


    I have applied the changes but it didnt worked , bandwidth was still slow 20 mbps out of 400 mbps link  . Than i created anoter Test SSID and made the some changes ( i selected WPA 2 AES instead of TKIP in test SSID ) and implemented 802.1x for this new Test SSID when i made a speed test it was giving me almost 170 mbps means it was giving me the desired result . So i replicated the Same configuration for my Staff SSID and its working fine now . I am attaching the screenshots of the changes which i have made on WLC and it had solved my issue .Hope if anybody else facing this issue it might give them some relief . I am really thankful to you and all other community members who are trying to help others .


    Cheers ,

    The TKIP standard limits you to 54 megs.  It is also insecure, so don't use it.
