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.

I have a netbook and desktop with Ubuntu on both. I wanted to make my desktop wireless so I can move it and get rid of the cable. I used a Broadcom 4320 (Linksys) usb dongle. It works fine on the netbook but won't work on the desktop. I tried everything I could think of but can't get it to work. I posted on Ubuntu forum and was able to resolve it. So I went out and bought another dongle and got the same thing.
So I found this in my sys.log.....

It keeps asking for the key about every 20 seconds or so but never authenticates. I installed wicd and it shows "validating Authentication" and then stops at that point.
I have seen similar post but no fix action.
The new usb dongle is a netgear n150. My desktop computer has a fresh Ubuntu install, 4 days ago I think. Its a slightly newer kernel I believe than my netbook.
Another tid bit, I opened up Wicd and plugged the Linksys (broadcom) usb back in and Wicd doesnot see it. I did lsusb abd its there. Rebooted and tried again, nothing. So I swapped back to the Netgear N150 and it sees it, but hangs on Validating Authentication.

Reason: extra info
I figured it out and feel like a FOOL! Never ever try to read a key in small print with no glasses! Some how I inserted an extra I in the key. I found it when I was helping my son to put his X-box on the wifi and ran into the same problem. I went back to the modem looking for something else and had my glasses on and a flash light. I looked at the key and and noticed from memory it wasn't right. AARRRGG!
