ifconfig <interface> up


Wireless Bringup on Boot

The wireless interface bring-up behaviour can be configured within /etc/network/interfaces.d.


Connecting to Networks (wpa_supplicant)

A network connection can be established by starting the wpa_supplicant daemon. The WPA supplicant requires a configuration file with a list of network configurations to use for connection.

wpa_supplicant -Dnl80211 -c/etc/wpa_supplicant.conf -iwlan0 -B
