=== Installing wpa_supplicant ===
AtRPMS contains packages for [[:Category:Fedora|Fedora Core]].

*Get the [http://hostap.epitest.fi/wpa_supplicant/ source]
*Make sure your kernel includes the drivers for your wireless card. Here's a sample .config for [[madwifi]] users:

#
#.config
#
# Uncomment following two lines and fix the paths if you have installed openssl
# in non-default location
#CFLAGS += -I/usr/local/openssl/include

CONFIG_CTRL_IFACE=y

* install wpa_supplicant by {{cmdroot|make && make install}}

=== Configuration ===

Set {{path|wpa_supplicant.conf}} to the following:

You have to change the values according to the response of {{cmdroot|wpa_passphrase <yourAPssid> <yourpassphrase>}}.

==== For WPA-PSK ====
<pre>
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
# ap_scan=2 was the one for me you may try 0 or 1 indstead of 2
ap_scan=2
fast_reauth=1

network={
ssid="my_network"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
group=TKIP
psk="secret_password"
}
</pre>

==== For WPA2-Personal ====
<pre>
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1

network={
ssid="my_network"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="secret_password"
}
</pre>

=== Starting wpa_supplicant ===
====When using a recent [[ipw2200]] driver ====
When using a recent [[ipw2200]] driver (e.g., as found in recent mainline kernels):
:{{cmdroot|wpa_supplicant -d -c/etc/wpa_supplicant.conf -ieth1 -Dwext}}
If every thing works as expected, you can replace <tt>-d</tt> by <tt>-B</tt> for the deamon mode.

In the instructions below, replace the interface name <tt>ath0</tt> with the appropriate one (usually <tt>eth1</tt>).

====When using the [[madwifi]] driver ====
Make sure that the modules <tt>ath_pci</tt>, <tt>ath_hal</tt>, <tt>ath_rate_sample</tt>, <tt>wlan</tt>, <tt>wlan_tkip</tt> and <tt>wlan_xauth</tt> are loaded (using {{cmdroot|lsmod}}).

Now you are able to start wpa_supplicant by
:{{cmdroot|wpa_supplicant -d -c/etc/wpa_supplicant.conf -iath0 -Dmadwifi}}
If every thing works as expected, you can replace <tt>-d</tt> by <tt>-B</tt> for the deamon mode.

====Bringing up the network card manually====
*Bring up the network interface with {{cmdroot|ifconfig ath0 <yourip> up}}.
{{NOTE|1=At the moment there is a problem within the madwifi driver or wpa_supplicant passing dhcp. ThatÂ´s why I use a fixed IP.
There are two patches one for wpa_supllicant (http://hostap.epitest.fi/bugz/show_bug.cgi?id=63) and one for madwifi
(http://article.gmane.org/gmane.linux.drivers.madwifi.devel/1275). Each one is supposed to work.}}
*Change the routes and add the default gateway.

====Bringing up the device at boottime (for {{Gentoo}} users)====
*Make a symbolic link
:{{cmdroot|cd /etc/init.d/}}
:{{cmdroot|ln -s net.lo net.ath0}}
*Copy {{path|wpa_supplicant.conf}} to {{path|/etc/conf.d/wpa_supplicant}}.
*Edit {{path|/etc/conf.d/net}}

#
#net
#
modules=( "wpa_supplicant" )
wpa_supplicant_ath0="-Dmadwifi"modules=( "wpa_supplicant" )
wpa_timeout_ath0=60
config_ath0=("<yourip> netmask 255.255.255.0")
routes_ath0=("default gw <yourgateway>")

*Add net.ath0 to the default runlevel by executing
:{{cmdroot|rc-update add net.ath0 default}}
*Make sure all needed modules are in {{path|/etc/modules.autoload/2.x}}
