Installing wpa_supplicant

  • Get the source
  • Edit the .config file in the source directory according to your wlan driver (see driver section)

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

Configuration

For WPA-PSK

  • Edit wpa_supplicant.conf:
 #
 #wpa_supplicant.conf
 #
 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=""
       proto=WPA
       key_mgmt=WPA-PSK
       pairwise=TKIP
       group=TKIP
       psk=
 }

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

Starting wpa_supplicant

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.
  • 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
 #
 wpa_supplicant_ath0="-Dmadwifi"
 wpa_timeout_ath0=60
 config_ath0=("yourip netmask 255.255.255.0")
 routes_ath0=("default gw yourgateway")
  • Add net.ath0 to runlevel by
# rc-update add net.ath0 default
  • Make sure all needed modules are in /etc/modules.autoloa.d/2.x
