Hello Devz,
I received my new Raspberry Pi 3 today with its integrated Wi-Fi, and I was wondering how to setup the ip address in a permanent way with console only.
sudo nano /etc/network/interfaces
Then find a line containing “wlan0” (zero) and replace the text by this:
allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-ssid "ssid" wpa-psk "password"
Enjoy!
