- 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 the default runlevel by executing
# rc-update add net.ath0 default
- Make sure all needed modules are in /etc/modules.autoloa.d/2.x
