802.11n 2.4 Ghz max speed 70 Mbps

[svelasquezm]

Hi,

I hava installed a WLC 2106 with 4 1252 Aps. Some laptops has dual radio wireless card, but others has just 2.4 Ghz card.

I have one SSID with WPA2/AES and 802.11X authentication.

With the laptops with dual radio the speed is in 300 Mpbs, but when is single 2.4 radio the max speed is 70Mpbs

If i use a 1252 ap with autonomous IOS, SSID with WPA2-PSK/AES this laptops single in 2.4 works to 144 Mbps

is there a knowed issue about 802.11x in 2.4 Ghz or i need to make a different configuration to can work in 2.4 with a speed of 144 Mbps?

Thanks a lot,

Your WLC is the bottleneck.  The 2100 only has 100 Mbps ports.

Another thing is that it may not be the only difference. There's a chance that the 11n adapters that are single band are also single stream.

My Acer netbook at home is said to be 11n single band but is actually limited to single stream so 70Mbps with no channel bonding.
