Setting up USB Wifi with BeagleBone Black

Playing with using a USB wifi with my BeagleBone Black running Debian (helpful link).  First step was to make sure the driver was installed which it should be (apt-get install firmware-ralink).  Then uncomment /etc/network/interfaces per your need:

# WiFi Example

auto wlan0

iface wlan0 inet dhcp

    wpa-ssid "essid"

    wpa-psk  "password"

To prevent people from seeing your password change permissions to root only:

chmod 600 /etc/network/interfaces

Power down, install the USB Wifi and it should connect.

If you don't know the name of the ESSID you want you can scan for available wifi ports using the following:

iwlist wlan0 scanning | grep ESSID
