This article will guide you through the necessary steps to install ipw3945 wireless adapter on a CentOS / RHEL based distribution.

Before we start, make sure that you have rpmforge repository configured. If you do not have, download it from here.

# wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

# rpm -ivh rpmforge-release-0.5.2-2.el5.rf.i386.rpm

Or

# rpm -Uvh http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

Now install required packages,

# yum install ipw3945d ipw3945-firmware dkms dkms-ipw3945 wpa_supplicant -y

Open wpa_supplicant file and edit as below.

# vim /etc/sysconfig/wpa_supplicant

# wlan0 and wifi0
# INTERFACES=”-iwlan0 -iwifi0″
#INTERFACES=”-iwlan0″
INTERFACES=”-ieth1″
# ndiswrapper and prism
# DRIVERS=”-Dndiswrapper -Dprism”
#DRIVERS=”-Dndiswrapper”
DRIVERS=”-Dwext”

Save and exit the file.

Edit wpa_supplicant.conf.

# vim /etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

#ctrl_interface_group=wheel
eapol_version=1
ap_scan=1
fast_reauth=1
#Work WPA-1
network={
ssid=”Dhaval_Soni”
psk=”Test@123″
priority=1
}

Create your wireless interface configuration file.

# vim /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
BOOTPROTO=dhcp
HWADDR=00:00:00:00:00:00 # Your wireless adapter’s MACid
ONBOOT=no

To get wireless adapter’s MAC id, use

# ifconfig -a

Start required services on boot.

# chkconfig ipw3945d on ; chkconfig wpa_supplicant on

To use the new boot order, first disable services, then re-enable.

To disable:

# chkconfig network off ; chkconfig ipw3945d off ; chkconfig wpa_supplicant off

To enable the new boot order;

# chkconfig network on ; chkconfig ipw3945d on ; chkconfig wpa_supplicant on

Note: Disable NetworkManager and NetworkManagerDispatcher services.

# chkconfig NetworkManager off ; chkconfig NetworkManagerDispatcher off

Again install required packages.

# yum install dhclient wpa_supplicant-gui

Start wpa_gui application and connect to the network.

# wpa_gui

Try to request an IP address from the network.

# dhclient eth1
