Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Ok, this means that your computer has wireless card, the commands can be executed, the network card to use for wireless is wlan2 but the scan comes up empty. Can you reboot your wireless access point, router, or whatever you connect normally to? And after that run the command like this again:
iwlist wlan2 scan
It should show output like below (this is from my computer, showing two wireless access point, from which one is mine)
Do you know which one is yours? Then write down the ESSID and the address.
Then next run the following commands:
iwconfig wlan2 essid "Your ESSID"
iwconfig wlan2 key "Your_key"
iwconfig wlan2 ap 00:00:00:00:00:00 (the 00 address must be substituted by the address of your wireless access point)
iwconfig wlan2 up
The quotes around the ESSID key and your_key must be typed also.
Normally if everything is working correct and you don't get any errors, you'll be connected to the wireless router.
