Odroid Wifi Module 4

We use the Odroid Wifi Module 4 to connect a computer directly to the GoPro Hero 4 Black that's mounted to the outside of the sub. However, since the computer is running Ubuntu server, it does not have run network-manager like the desktop version, and does not automatically bring up the wifi module on the wlan0 interface. Connect to an existing wifi network with the following instructions:

1. Ensure that the computer has internet access
2. apt-get install wpasupplicant
3. ip link set wlan0 up
4. wpa_passphrase <SSID> <password> where SSID is the name of the wireless network and password is the network's password
5. Copy the resultant string of characters from psk=...
6. Add the following interface to your /etc/network/interfaces file: auto wlan0 iface wlan0 inet dhcp wpa-ssid <SSID> wpa-psk <copied psk string>
