My wireless network was very good before putting Cisco WLC 4402 with version 22.214.171.124.
In my network there are two SSID's one for official and another for guest, which is working one single LAP 1142.( Total 12 LWAP is here)
we decided to manage all the ap and deployed WLC but now wireless network is very slow, local gateways is pinging with 80 ms. before WLC it was 1 ms.
Pls. suggest or come up with question to reach a solution.
Make sure APs and WLC ports are hardcoded to full duplex/100Mbps.
