Installing wpa_supplicant

AtRPMS contains packages for Fedora Core.

  • Get the source
  • Make sure your kernel includes the drivers for your wireless card. Here's a sample .config for madwifi users:

 CONFIG_CTRL_IFACE=y
  • install wpa_supplicant by # make && make install

Configuration

Set wpa_supplicant.conf to the following:

You have to change the values according to the response of # wpa_passphrase <yourAPssid> <yourpassphrase>.

For WPA-PSK

  
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"
}

For WPA2-Personal

  
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"
}

Starting wpa_supplicant

When using a recent ipw2200 driver

When using a recent ipw2200 driver (e.g., as found in recent mainline kernels):

# wpa_supplicant -d -c/etc/wpa_supplicant.conf -ieth1 -Dwext

If every thing works as expected, you can replace -d by -B for the deamon mode.

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

When using the madwifi driver

Make sure that the modules ath_pci, ath_hal, ath_rate_sample, wlan, wlan_tkip and wlan_xauth are loaded (using # lsmod).

Now you are able to start wpa_supplicant by

# wpa_supplicant -d -c /etc/wpa_supplicant.conf -iath0 -Dmadwifi

If every thing works as expected, you can replace -d by -B for the deamon mode.

Bringing up the network card manually

  • Bring up the network interface with # ifconfig ath0 <yourip> up.
NOTE!
At the moment there is a problem within the madwifi driver or wpa_supplicant passing dhcp. That´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
# cd /etc/init.d/
# ln -s net.lo net.ath0
  • Copy wpa_supplicant.conf to /etc/conf.d/wpa_supplicant.
  • Edit /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
# rc-update add net.ath0 default
  • Make sure all needed modules are in /etc/modules.autoload/2.x
