1. check the switch port setting where WLC is connetced (it should be 1000/full duplex or auto/auto)

2. check the AP connected switch ports

3. examine the WLC config for 2.4 and 5 Ghz. must use wpa2-AES to get 802.11n data rates.

I checked some AP load profile failed and some passed when I connected to "passed" speed was normal, but connected to "failed" speed was so down.
