Hi everyone, we have 2 wlc 5520 (in cluster) an use AIR-CAP3501I-E-K9 AP our wireless internet very slow. Have anyone faced this kind of issue? (use wired connection speed is ok and when we use 5508 befor speed was ok, too)
Thanks in advance
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.
