Configure Ubuntu 8.10 with IIUM Wireless (ARUBA)

As for my experience when the IIUM Wireless Environment has implemented, Ubuntu 8.10 (Intrepid Ibex) has a problem to connect to to the wireless network. One of the millions way to fix this problem is by downgrade the version of Network Manager to the previous version. This is the method that I use to enable me to connect to the wireless network. If you have much easier solution to fix this problem, you are welcome to share with us.
Lets get our hand dirty:

1. Open terminal

2. Kill related process

$sudo killall NetworkManager
$sudo killall nm-applet

3. remove network-manager application

$ sudo apt-get remove network-manager
