Hello,

I was wondering if anyone could offer suggestions on how to improve wireless performance on a Cisco 5508 controller.

I am told right below the AP there is little to no signal.

I understand there could be multiple reasons for this, any suggestions for improvements ?

There are 3702 and 1131 AP's
