maemo.org - Talk - WPA and Wirelesstools?

First off, I am a linux newbee, so please go easy!

I have a N800 running OS800 and I am using wirelesstools to connect to the wireless network. I'm basically connecting to the wireless network and then autostarting a RDP session upon booting.

My current setup is limited to WEP wireless and I would like to use WPA for better wireless security.

Here is the network script that I am using to get the network to autoconnect.

Code:

#!/bin/sh

#start network automagically



case "$1" in

     start )

          /sbin/ifconfig wlan0 up

          /sbin/ifconfig wlan0 192.168.1.1 netmask 255.255.255.0

          /usr/sbin/iwconfig wlan0 mode managed essid MY_SSID key My_KEY

          # No Default Route

          ;;

     stop )

          : Do Nothing

          ;;

     * )

          echo "Unsupported Argument '$1'"

          ;;

esac

exit 0

Is there any way to make a few changes and use WPA instead of WEP?

Thanks,
