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've tried several distro's over the past couple of days before settling on Ubuntu, but I've never got my WiFi working (it was fine under Windows, but I'm determined not to go back). Now that I've installed Ubuntu 9.04, my machine finally owns up to having a wireless device and I think the problem is now down to my being a total Linux noob...

If I click on the NetworkManager applet it tells me that wired network "auto eth01" is active, but there are no wireless networks (I've tried adding a wireless network manually, but it just makes up some IP 10.x.x.x address and fails to connect to anything)
NB I did find a note on the ubuntu.org forum about 9.04 shipping with an alternate driver for Atheros devices, but if I activate that, then NetworkManager no longer mentions wireless networks at all.
I'm sure I'm missing the point somewhere along the line, but I just can't get my system to detect any access points (most neighbours have them), so any advice would be gratefully received.

Reason: Missed some info in original post
This will automatically uninstall network-manager in jaunty. I've just done a fresh install of jaunty on my laptop, and had similar issue, though not same hardware as you. If this doesn't work for you, just issue:
1) to get wicd, what repository does one point to?
2) Initial use of Network Manager worked great under 9.04. Saw all the local wifi networks in my neighborhood. I was able to connect to my local network and my neighbors. After several reboots I no longer see any wifi networks including my own home network. Any thoughts?
I had one hell of a time getting wifi drivers to work under Hardy with my AR5007 card. Following the suggestions of 'Nicedude' I was able to get it work after much effort. I used one of the earlier madwifi drivers with wicd.
When I upgraded to Intrepid, these drivers no longer worked, but I had success with the 'compatibility' drivers I found on madberry.org. You may want to try those. The wifi card identified itself as something else and the website has a test set you can run to see if the drivers are likely to work for you.
I was also pleasantly surpised to see that the wifi worked out of the box with Jaunty, but unfortunately this doesn't work for everyone. I attributed this to the concept that restricted drivers for the AR507 card.
I have dual booted my OC with Ubuntu 2.6. Now to go to Windows I have to go through GRUB. Bootable Windows CD's do not work. How can I solve this problem
Asking a new question in the middle of an existing thread that is unrelated to what you want to know is called "hijacking". It is not a good thing to do because the questions and answers get mixed up which makes things difficult for all.
Please do not hijack threads. Create a new thread to ask your question.
Thanks for your cooperation.
Decided, as I'd got nowhere with Linux as yet, to install fresh from scratch and try the instructions out. So I've followed the instructions up to step 3, issued the "make" command, and I've noticed in among the output, about a dozen warning messages. There are two types:
athstats.c:288: warning: format not a string literal and no format arguments
wlanconfig.c:779: warning: ignoring return value of 'system', declared with attribute warn_unused_result
(obviously, the detail varies between messages)
Is this a problem? Or should I be able to carry on through the rest of the instructions?
Well ... I gave up. I've spent hours following instructions - often conflicting - and got nowhere. I got myself a USB WiFi adapter from Amazon. Within 30 seconds of the parcel arriving, I was on the 'net using WiFi. For me, the moral of the story is "Avoid Atheros". My next laptop will not have one of their adapters.
(If anybody is interested, the adapter that I bought was EDiMAX RALink RT2501USB - highly recommended ... IT.JUST.WORKS)
