Wireless network

First off, you need wireless_tools installed (swup --install wireless_tools)

edit /etc/modules.conf if on TSL 2.2 or /etc/modprobe.conf if on TSL 3.0 and add an alias for your card, and any options you might need;

alias <device> ipw2200
options <device> debug=0

if you are using TSL 2.2 with a 2.6 kernel, rerun generate-modprobe.conf > /etc/modprobe.conf

make an ifcfg-<device> in /etc/sysconfig/network-scripts/

See the top of /etc/sysconfig/network-scripts/ifup-wireless for list of options you can specify in ifcfg-<device>

More tips

make sure kernel.hotplug and kernel.modprobe is set properly by init (http://bugs.trustix.org/show_bug.cgi?id=114#c1)
use ifup/ifdown to bring a network interface up and down
if using hotplug, and ifup complains that <interface> seems to be down, make sure you have followed the first tip, then rmmod the module
