1. 添加 atrpms 源
# gedit /etc/yum.repos.d/atrpms.repo
添加以下內容：
代碼:

[atrpms]
Core $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/fc$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
enabled=0
gpgcheck=1

安裝 key：
# rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms

2. 安裝驅動
# yum --enablerepo=atrpms install ipw3945-kmdl-`uname -r` ieee80211-kmdl-`uname -r`

3. 打開無線網卡
腳本：
代碼:

#!/bin/bash
#
# ipw3945d Load/Unload Intel ipw3945 daemon
#
# chkconfig: 2345 09 90
# description: Load / Unload Intel ipw3945 daemon
#
### BEGIN INIT INFO
# Provides: ipw3945d
### END INIT INFO

# Source function library.
. /etc/init.d/functions

if [ ! -f /etc/sysconfig/network ]; then
exit 0
fi

case "$1" in
start)
echo -n "Starting ipw3945d:"
/sbin/ipw3945d > /dev/null 2>&1
echo
;;
stop)
echo -n "Stopping ipw3945d:"
killproc ipw3945d
echo
;;
status)
status ipw3945d
;;
restart)
cd "$CWD"
$0 stop
$0 start
;;
*)
echo $"Usage: $0 {start|stop|restart|status}"
exit 1
esac

exit 0

把上面的代碼保存為 ipw3945d。
# mv ipw3945d /etc/init.d
# chmod +x /etc/init.d/ipw3945d
# chkconfig --level 5 NetworkManager on
# chkconfig --level 5 NetworkManagerDispatcher on
# chkconfig --level 5 ipw3945d on
# service NetworkManager start
# service NetworkManagerDispatcher start
# service ipw3945d start

4. 測試
# ifconfig
# iwlist scanning

完成
