Hi,
there was no interference between APs and CCM encryption was configured, but slow speed was encountered even if the client was right next to AP with maximum signal and only one connected to the network.
Next step was to verify the clients connected to SSIDs, with below commands:
(Huawei)display station assoc-info all
// will display all the clients connected to Wireless network
(Huawei)display station assoc-info sta xxxx-xxxx-xxxx
// will display all the information regarding a client (identified by MAC address), xxxx-xxxx-xxxx represents the Mac address
<HAS-WAC>display station assoc-info sta 1c56-fe04-5259 //below is the client's\STA's, connected to the wireless network, information
