USB Wifi Example

In this notebook, a wifi dongle has been plugged into the board. Specifically a RALink wifi dongle commonly used with Raspberry Pi kits is connected into the board. Using Linux calls and Python functions, we will determine the unique name of the dongle and then create a network entry for a known ssid/password pair. This demo was first done using an iPhone hotspot wireless connection.
