Thinkpad T41p and Fedora Core 5

Installed FC5 off all 5 cdroms.
During installation, configured monitor for "LCD 1400×1050"
eth0 was auto-discovered, but not ath0 (wireless).
Get eth0 up: ifconfig eth0 up, route add default gw
vi /etc/resolv.conf, and add line "nameserver"
Downloaded madwifi drivers (.tar.gz) from
Untar’d to tmp dir
Requires kernel srcs! So, ‘yum install kernel-devel-[match kernel version].i686’
yum install gcc (for building madwifi)
cd madwifi_subdir
make install
modprobe ath_pci
ifconfig -a (should see ath0 now)
Load scanner: modprobe wlan_scan_sta
ifconfig ath0 up
iwlist ath0 scan (view APs in the area and which are encrypted)
iwconfig ath0 essid "default"
iwconfig ath0 key <wep key in hex>
dhclient ath0

(this is from the madwifi "newbie howto" doc)
