Estoy jugando un poco con la Raspberry 3 que tengo y quería desactivar el wifi, porque no lo utilizo.
Para listar las interfaces:
ifconfig
Sale por pantalla:
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.6.11 netmask 255.255.255.0 broadcast 192.168.6.255 inet6 fe80::e9b:2345:56d7:12345 prefixlen 64 scopeid 0x20 ether b8:27:eb:3c:90:7d txqueuelen 1000 (Ethernet) RX packets 240 bytes 45980 (44.9 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 100 bytes 20365 (19.8 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

Para desactivar el wifi:
sudo iwconfig wlan0 txpower off
Volvemos a ejecutar para listar las interfaces:
ifconfig
Sale por pantalla:

Al volver a iniciar el sistema, ya no estará activado el WIFI.
