There was no interference between APs and CCM encryption was configured, but still slow speed was encountered even if the client was right next to AP with maximum signal and only one connected to 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 adress
<HAS-WAC>display station assoc-info sta 1c56-fe04-5259 -below is the client's\STA's ,connected to wireless network, information
Station mac-address : 1c56-fe04-5259
Station ip-address : 10.2.18.27
Station gateway : 10.2.18.1
Associated SSID : Test
Station online time(ddd:hh:mm:ss) : 000:00:44:15
The upstream SNR(dB) : 37.0
Station connect rate(Mbps) : 45
Station connect channel : 6
Station inactivity time(ddd:hh:mm:ss) : 000:00:00:00
Station current state
Authorized for data transfer : YES
Qos enabled : YES
ERP enabled : YES
HT rates enabled : YES
Power save mode enabled : YES
Auth reference held : No
UAPSD enabled : No
UAPSD triggerable : No
UAPSD SP in progress : No
This is an ATH node : No
WDS workaround req : No
WDS link : No
Station's HT capability : P
Station ERP element : 0
Station capabilities : EPSs
Station's RSSI(dBm) : -71
Station's Noise(dBm) : -108
Station's radio mode : 11n
Station's AP ID : 1
Station's Radio ID : 0
Station's Authentication Method : WPA2-PSK
Station's Cipher Type : CCMP
Station's User Name : 1c56fe045259
Station's Vlan ID : 218
Station's Channel Band-width : 20MHz
Station's asso BSSID : 70d9-311a-2304
Station's state : Asso with auth
Station's Qos Mode : WMM
Station's HT Mode : HT20
Station's MCS value : 7 -the client connected to network, is MCS class 7
Station's Short GI : nonsupport
Station's roam state : Yes
=>if you take a look into below 802.11n standard table, the client(sta) is from MCS class 7 (1xMIMO, 20Mhz), therefore the Speed will be 65MBs => download speed will be: 65/8 = 8 MBs, so in our case 10MBS is ok.
=>the limitation is no given by AP, in this case the limitation of speed is given by MCS class(7) of the CLIENT which connects to wireless.
=>with other words, the STA connected to Wireless network it is an 1x MIMO client, MCS class 7, supports speed to 65 MB\s in 20MHz channel.
=>a STA with higher MCS value, connected to your Wireless network, will have higher speed, of course depending how many STAs are connected to network.
