-===== Using WLAN =====+==== Using WLAN ====
 The ssid and password might have to be changed in a prebuilt image according to your local setup. Modify the file ///etc/wpa_supplicant.conf// by replacing the ssid with your WLAN name and set the password to your password. Your router will assign an IP address in the ''192.168.1.xx'' range. Check for the assigned number with //sudo /sbin/ip a// and search for the entry //wlan0//. The ssid and password might have to be changed in a prebuilt image according to your local setup.
