How to configure 802.11n on WLC4404 or WLC5508 in 2.4Ghz?

Hello community,

Tell me how to set up support 802.11n on WLC4404 or WLC5508 in the 2.4Ghz?

WLC4404 supports 802.11n? or support this protocol only in the brochures? I spent a few days, but did not get the result.

I'm connected at speeds 65/130Mbit, but the real speed tests never exceeded 45Mbit. The AP from the test laptop is 7-10 meters.

I tested the laptops with a Linksys AP E1200-EE ( 40Mhz, FastEthernet uplink port...)and received nearly 100Mbit!

At WLC5508 able to connect at speeds 150/300Mbit/c but only in the 5GHz band, but real speed tests never exceeded 70Mbit.

In 2.4Ghz range I connected at speeds of 130/144Mbit/c, but actual measurements showed no more than the 45Mbit.

All tested with iperf and with site speedtest.net.

iperf -w64K -s

iperf -w64K -i 2 -t 300 -c x.x.x.x

Laptops: Asus (Atheros AR9002WB-1NG) and Sony (Advanced-N 6230).

My tests AP: 3501I-E and 1252AG-A

SW on WLC5508 7.2.110.0

AP tested in different variants - open system and WPA2+AES.

Please, give me advice.

Some output from WLC5508:

Alex:

Are you using 40 mhz channel width for 802.11a?

Using 40 mhz channel gives better results.

This configuration of channel width is available only with radio 5 ghz and not with 2.4 ghz that's why with 5 ghz using 802.11n is more efficient.

How to configure 802.11n on WLC4404 or WLC5508 in 2.4Ghz?

Yes, in my lab I used 40mhz channel with 5ghz, but for me interesting 2.4Ghz range because in our region not very common device for 5Ghz.

I will be satisfied in the 2.4Ghz range with the real speed is closer to 80-100Mbit, but I cannot get more than 45Mbit.

You need to remember that wireless is half duplex. So if your client connects at 144mbps, your max throughput is half.... 72mbps. What you connect at does not mean your actual throughput. Make sense?

Hi,

To be able to use N data rates on either the 5GHZ or the 2.4GHz you just need to make sure that you have enable the N data rates on the WLC under the wireless tab, then configure on the WLAN you will be working with to use WPA version2 with AES as the encryption and enable WWM or no encryption with WMM enable.

Also make sure that you have N access points and that the wireless clients supports N.
