When dealing with "strong" encryption of WiFi networks, you have to setup a WPA or WPA2 configuration. To handle the requirements of these protocols during association, a userspace daemon is needed: it is called a WPA supplicant. The most used one on Linux is wpa_supplicant; we will see here how to install and configure it.

Note: wpa_supplicant is also able to handle WEP connections |
Installation
$ make menuconfig
Package Selection for the target --->
Networking --->
[*] wpa_supplicant
[ ] Enable WPA with EAP
[*] Install wpa_cli binary
[ ] Install wpa_passphrase binary
EAP is only needed if you plan to use WPA in Enterprise mode == with a Radius server.
You also have to install drivers to make WPA Supplicant work:
$ make linux26-menuconfig

Usage
wpa_supplicant needs a configuration file in /etc/wpa_supplicant.conf. Here is an example:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
network={
ssid="SSID"
scan_ssid=1
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
psk="PASSPHRASE"
}
# wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
