Ok here is how you install an Agere Wi-Fi card, with an Intersil 802.11b chipset (find out your chipset by opening up KDE's control center, or type kcontrol into your terminal, and then looking at your PCMCIA devices.)

1. Download the .src.rpm for your kernel, and run the following command:

rpm -ivh kernel-#.#.#-#.#.src.rpm

2. Step 1 created a tarball in /usr/src/redhat/SOURCES that contains all of your kernel source files, and we need to untar that file, so run the following command:

tar -xzvf /usr/src/redhat/SOURCES/kernel-#.#.#-#.#.tar.gz

3. Symlink the directory that was just created by untarring those files, to /usr/src/linux, using the following command:

ln -s /usr/src/redhat/SOURCES/kernel-#.#.#-#.# /usr/src/linux

4. Now go to the following URL, and download the drivers for your card:

http://www.hpl.hp.com/personal/Jean_...ls.html#latest

5. Untar the file that you just downloaded, then browse to the directory that untarring that file created

6. Run the following command:

./Configure

This should display a menu of stuff, you probably just want to use the default values, so go ahead and do so. For the first option use /usr/src/linux if it's not already a default value.

7. After that finishes running, run 'make', and then 'make install'. After that reboot your system, and then go into kcontrol or some other network device manager, and add your wireless card, mine was eth1. Once that's done you should reboot your system again. When it comes back up, goto a terminal and type 'iwconfig', and it should display eth1 as being a wireless adapter. Then just find service and enjoy

Good luck.
