Wireless Access

Hi,

I am using RAP5wn and getting 54 mbps speen over n client. i have also checked the laptop's wireless adapter setting which is fine. can i do any changes into the controller to bost up the speed.

Thanks

Are you using WPA-TKIP?  The 802.11n standard only allows 802.11n or HT speeds if you are doing Open or AES.

I  am using WPA2 psk.

Is it WPA2-TKIP or AES?

It's AES ......

Okay.  Under the SSID profile, there is an HT SSID profile.  Make sure HT is enabled.

that also i have checked and its enabled.................

Type "show ap bss-table" on the commandline and make sure under the "phy" column, it says g-HT

Also type show ap association to see what rate it is associated at.

Is the client an 802.11n client?

i have checked and i m attaching the screen shoot of the screen..............

It says the client is associated at g-HT-20-2SS, which is 802.11n.  Where does it say that it is only associated at 54 megs?  Is the client far away from the access point?

type "show ap debug client-table ap-name <name of ap>" to see the TX rate and RX speeds of your clients:

(host) # show ap debug client-table ap-name AP-135

client is near to the AP and on the wireless ststus it is displaying 54 mbps.......

The wireless status where?  Windows?  That has errors quite a few times.  The controller says your client is associated at 802.11n.

Have you run any performance/throughput test on your client device? This could be just the OS mis-reading the NIC or a graphical issue only. Try iperf or jperf. Those are good for telling. If it is only running a lower rate, try updating the NIC driver if it's old.
