On my first visit to the International Institute for Social Entrepreneurship (IISE) here in Kerala I found that they were having trouble configuring the USB Wireless (Wifi) Network Card for gnu/Linux. They use this device for all their desktops and some older laptops, this device is not very commonly used here in India and there is very little documentation about it in English. The Chinese make TP-LINK TL-WN322G+ USB Wireless Network Card is supported very well in gnu/Linux with a builtin module zd1211rw now included in main linux kernel tree, thanks to the zd1211 project.
On their Ubuntu 8.04 (HH) desktop computer I first checked the USB ID of the chipset then inserted the zd1211rw module with modprobe command and the devices started working like magic.

$ sudo modprobe zd1211rw
Append to new line with 'zd1211rw' at the end /etc/modules file so that the module is loaded every time the computer boots.
