user Connection speed

kiran — Sun, 04 Jul 2021 02:36:42 GMT

Hi,

I have 1252 LAP connected to WiSM's, 802.11n enabled in the network,

Broadcasted 2 SSID's HR and ADMIN
HR with no authentication and unsecured .... ADMIN with WEP enabled,

when user connect to HR SSID, he gets connected at 72Mbps speed,
but the problem is when user connects to ADMIN SSID, user gets connected at 54Mbps always,

can some one tell me the reason for the same.

Hi Kiran,

802.11 N speeds has some criteria.. they are..

The WLAN should be..

1>> Open auth with no security and Encryption + all MCS rates enabled + WMM enabled.

2>> WPA 2 - AES encryption + all MCS rates enabled + WMM enabled.

Since your second WLAN is using WEP, the N speeds are not expected!!

lemme know if this answered your question..

Hi Kiran,

802.11n can be enabled only with one of the following security configuration:

1. Open (no authentication/encryption).
2. WPA2 AES (and possibly no other methods, so to force clients to use WPA2 AES only).

If your SSID is configured for WEP, 802.11n will not be enabled:

Thanks Surendra for fast response,

so you mean to say WEP will not support 'N' ... ok thanks...

so if I configure WPA2 with AES encryption it should connect at 72Mbps right ? I will try and let you know.

Thanks Fede for providing me with supporting document,

would you please mention which whitepaper to refer for the same ?

Hi Kiran,

yes you are right.. if you configure the WLAN for WPA2 AES(TKIP disabled) as encryption with all MCS rates enabled.. you will get the N speeds..

Just FYI.. If you are running N over G radio, then expected speeds will be max 144 Mbps.. and N over A radio will be 300 Mbps..

Lemme know if you face any issue!!

lemme know if this answered your question..
