As the WiFi driver is not statically linked to the kernel image, it is necessary to load the module first:

Add the passphrase key to the <code>wpa_supplicant</code> configration configuration fileand make it readable by <code>root</code> only:
<pre class="board-terminal">
root@arm:~# wpa_passphrase SSID_ZyXEL_WPA2 >> /etc/wpa_supplicant.conf
ZyXEL-WPA2-PSK
root@arm:~# cat chmod 0600 /etc/wpa_supplicantwpa_supplicant/ wpa_supplicant.conf
root@arm:~# cat /etc/wpa_supplicant.conf
# reading passphrase from stdin
beacon int: 100

====Configuring WiFi interface automatically====It is possible to modify <code>/etc/networks/interfaces</code> in order to automatically start and configure the WiFi interface on every boot. The following example shows After assigning a configuration with (static ) IP addresses. The address to the <code>wpa-pskwlan0</code> string interface, it is retrieved from possibile to ping the <code>/etc/wpa_supplicant.conf</code> file.Access Point:

Also, it is required In order to automatically load the <code>wl12xx</code> module on startup, issue the following command:
root@arm:~# echo wl12xx >> /etc/modules
