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'm running Ubuntu 6.10 on an HP xv5000. There is a hardware button that turns on the wireless network card, and I can't get that to work. I've installed the proper driver with ndsiwrapper, and I activated it with the command:
"So I'm not sure whether the network card is actually powered up even though the button won't light."
That would be the first clue that it's not. Broadcom cards need extra work. You can use a driver wrapper like ndiswrapper or try your attempt at the drivers people are writing for them. Either way, it's not just gonna work on it's own.
It may seem obvious that the card isn't powered up unless that light is on, but I have seen posts on various lists like these from people who say things like "I finally got it working, even though the light doesn't light up." So part of my question was to ask if the output from iwconfig tells me whether the device is working or not.
Well, it's not working, as the forums should also show you that you need to set up broadcom based cards. They don't normally work right out of the box. There's driver wrappers, and an open source project. Pick one and try it.
Which driver are you using bcm43xx or ndiswrapper. Take a look at this sites wiki. It contains step by step setup instructions. I have a zv5000 laptop. It uses "Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)
". I use ndiswrapper. In my case I had to wait a while until I could find a 64-bit windows driver I could download. Also, I found that the version of ndiswrapper that ships with SuSE 10.1 had problems. I had downloaded an earlier version of ndiswrapper that I used with SuSE 10.0, and used "rpmbuild -ba ndiswrapper.spec" to build a pair of ndiswrapper rpms to install. I do this after a kernel upgrade as well.
Another of the wireless-tools programs "iwlist" is good for quickly determining if your wireless device is configured. Try "iwlist <device-name> scan" to see if it can detect access points. If it can, then the device is probably working and you can work on your wpa_psk configuration. Before the device authenticates, you won't get an IP assigned via DHCP.
You can use "lsmod" to list what kernel modules are loaded.
One additional note about bcm43xx.... You must install firmware for it to work. This is tripping up a lot of people in that distros now include the bcm43xx module, but not the firmware. Without both, you don't have a functioning card.
i took my 2200bg card and put it into another laptop. had to use the masking tape trick and cover some pins to get it to work. But I had very very bad stability issues. Almost every hour I get disconnected a few times. It just loses connection for no reasons. We got a dozen of them, and I think its got to do with the power management. Or I'm getting void11 by wardrivers.
