Setup for static connection[edit | edit source]
Check that the interface is properly intialized:
root@desk-mx8mp:~# ifconfig mlan0

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)

Setup the wpa_supplicant.conf configuration file for handling the WiFi connection, for example:
root@desk-mx8mp:~# cat /etc/wpa_supplicant.conf
network={
ssid="ZyXEL"
key_mgmt=NONE
}
Apply the wpa_supplicant.conf configuration file manually starting the wpa_supplicant:
