How do you install a wireless card on linux? using FC4?
what are the steps involved?

First you should check the HCL here to make sure the card you buy is supported in some way. Once you've got your card..

Natively Supported Card
1. Install the wireless card and boot your system
2. use lspci to determine the chipset of the card. lsmod might tell you if it autoloaded the module for you
3. Using the chipset information, cd to /usr/src/linux and type make menuconfig
4. navigate to drivers and networking and there should be a wireless category.
5. Select your wireless card either as a M for module, or * for built-in kernel support.
6. exit and save changes
7. use the make && make modules && make modules_install

Non-Natively Supported Card

If your card doesn't include native linux support, you'll have to use a wrapper.

You'll need to extract the windows drivers onto a floppy and copy them to your linux system.
Install NdisWrapper from ndiswrapper.sourceforge.net

From there, you'll have to read the documenation on ndis's website and I only use natively supported hardware on my linux boxes.

if your card is the intel pro wireless 2200b/g kernel support does not work you have to to go to ipw2200 website for instruction to install it properly

Your kernel should serve this symbols too:

Symbol: IEEE80211 [=m]
│ Prompt: Generic IEEE 802.11 Networking Stack
│ Defined at net/ieee80211/Kconfig:1
│ Depends on: NET
│ Location:
│ -> Networking
│ -> Networking support (NET [=y])
│ Selected by: HOSTAP && !UML && NETDEVICES && NET_RADIO

Without that you cannot use wireless-tools, which i would suggest too.

So the most (distributive) Kernels have this symbol the task goes as follows:

check for module/driver
compile module/driver (if needed because you have to use outer Linux sources)
install module/driver into running kernel (insmod/modprobe)
use wireless-tools to configure device

What does "use lspci" mean? Details on how and where to execute that would be helpful.

...lspci makes the informations out of /proc/sys (as i think) listed in human-readable form...

...on debian it's in the package pciutils.

...similar to lsusb (usbutils)...or similar (geek)...

...on cleaning up my bookmarks i found this (maybe gives help): http://www.hpl.hp.com/personal/Jean_...nux/Tools.html

lspci & lsmod are commands you would type. Their output will help us/you determine the chipset & kernel module.

This is what I get when I type lspci in a terminal window:

[Altstatten@localhost ~]$ lspci
bash: lspci: command not found

What's this telling me?

You need to install the package pciutils since it wasn't included in the default installation of your linux distrobution, or possibly that you need to run it as root.

Development: I have not yet done any of the above suggestions because when I plug into the internet cable it works. Also, the wireless card then works when I remove the cable UNTIL I shut off the computer. Turn it on and the wireless card doesn't work any more.

Does that tell you anything?

If its not installed, please install pciutils package using your distro package manager.
