Configuration

Setwpa_supplicant.confto the following:

You have to change the values according to the response of
# wpa_passphrase
.

For WPA-PSK

ctrl_interface=/var/run/wpa_supplicantctrl_interface_group=0eapol_version=1# ap_scan=2 was the one for me you may try 0 or 1 indstead of 2ap_scan=2fast_reauth=1network={ssid="my_network"proto=WPAkey_mgmt=WPA-PSKpairwise=TKIPgroup=TKIPpsk="secret_password"}

For WPA2-Personal

ctrl_interface=/var/run/wpa_supplicantctrl_interface_group=0ap_scan=1network={ssid="my_network"proto=RSNkey_mgmt=WPA-PSKpairwise=CCMP TKIPgroup=CCMP TKIPpsk="secret_password"}

Bringing up the network card manually
Bring up the network interface with
# ifconfig ath0 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 (forGentoousers)
Make a symbolic link

# cd /etc/init.d/

# ln -s net.lo net.ath0

Copywpa_supplicant.confto/etc/conf.d/wpa_supplicant.
Edit/etc/conf.d/net

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

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

iw的编译和配置运行

iwis a new nl80211 (802.11 netlink interface) based CLI configuration utility for wireless devices.

Netlink Protocol Library Suite

iw requires theNetlink Protocol Library Suite (libnl)

Download, cross compile and install the Netlink Protocol libraries:

wget http://www.infradead.org/~tgr/libnl/files/libnl-3.2.24.tar.gz

tar -xzf libnl-3.2.24.tar.gz

cd libnl-3.2.24

./configure --host=arm-linux-gnueabi --prefix=/usr/arm-linux-gnueabi

make

make install

cd include

make install

iw

With the Netlink Protocol Library Suite prerequisite installed, download and build theiwnl80211 based CLI configuration utility:

wget https://www.kernel.org/pub/software/network/iw/iw-3.15.tar.gz

tar -xzf iw-3.15.tar.gz

cd iw-3.15/

export PKG_CONFIG_PATH=/usr/arm-linux-gnueabi/lib/pkgconfig

export CC=arm-linux-gnueabi-gcc

make

Manually install iw and required libraries on your target root-fs:

cp iw /home/export/rootfs/sbin/

cp /usr/arm-linux-gnueabi/lib/libnl-genl-3.so.200 /home/export/rootfs/lib/

cp /usr/arm-linux-gnueabi/lib/libnl-3.so.200 /home/export/rootfs/lib/

And update the dynamic linker run-time bindings on your target:

ldconfig -v

hostapd

hostapdis an 802.11 Access Point and IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator daemon.

Download, extract and build hostapd:

wget http://hostap.epitest.fi/releases/hostapd-2.2.tar.gz

tar -xzf hostapd-2.2.tar.gz

cd hostapd-2.2/hostapd

cp defconfig .config

make CC=arm-linux-gnueabi-gcc

make install DESTDIR=/home/export/rootfs
