Enable Wifi on Ubuntu Snappy
I recently spent more time than was necessary trying to figure out the “snappy” way of enabling wifi on my Raspberry Pi 2. After reading through the documentation, I was expecting to find an elegant snap or framework. Instead, in recent images all that’s required is to add to the following to /etc/interfaces.d/wlan0.
allow-hotplug wlan0 iface wlan0 inet dhcp wpa_ssid <SSID> wpa_psk <passphrase>
