ipw2200 on RHEL 4U1 / CentOS 4.1
--------------------------------
2005-06-21

You will need kernel-devel and gcc (and whatever dependencies) installed.

Download the latest driver and firmware from:
http://ipw2200.sourceforge.net/#downloads  (driver)
http://ipw2200.sourceforge.net/firmware.php  (firmware)

This was done on my IBM T42.
I did this as root, I'm sure you can sudo the commands.

1.  tar xvfz ipw-fw-2.3.tgz /lib/firmware
	You choose this location because /etc/hotplug/firmware.agent says:
	FIRMWARE_DIR=/lib/firmware

2.  tar xvfz ipw2200-1.0.4.tgz
3.  cd ipw2200-1.0.4
4.  make && make install
5.  vi /etc/sysconfig/network-scripts/ifcfg-eth1 (or whatever your wifi will be)
	DEVICE=eth1
	ONBOOT=yes
	BOOTPROTO=dhcp

6.  modprobe ipw2200
7.  if you have an ESSID and KEY put those in as well:
	(If your wifi is open, skip this step or see Notes below)
	ESSID=myessid
	KEY=ABCDE1234567890ABCDE123456

8.  once you have ifcfg-eth1 configured:
	ifup eth1


Notes:
If you want to scan the air for networks:
	iwlist eth1 scan

If you want to leave ifcfg-eth1 unchanged and switch between networks, you
can skip step #7 and create scripts that will change your settings at the
command line using iwconfig. (presumes you can sudo) Examples:

# script to set to specified ESSID and turn on the WEP key
# This will NOT change the parameters in ifcfg-eth1
# put your ESSID in place of <myessid>

sudo /sbin/iwconfig eth1 essid <myessid> key ABCDE1234567890ABCDE123456
sudo dhclient eth1

# script to set to any available ESSID and turn off WEP key
# This will NOT change the parameters in ifcfg-eth1

sudo /sbin/iwconfig eth1 essid any key off
sudo dhclient eth1

You might want to secure those scripts with chmod 700 since you may have WEP
keys in them.
