Wireless for the Raspberry Pi

Obviously my robot needs a wireless connection so I went to the Raspberry Pi Hardware Compatibility list to look for a small, cheap, compatible, wireless dongle.  I decided on the Belkin N150 and have been happy with it.   The RPi detects it on boot so all I needed to do was setup the network. Edit the network interfaces file /etc/network/interfaces.   The file should look like the below once you have added the wlan0 interface for the Belkin N150 (highlighted):

    auto lo
    auto wlan0
    iface lo inet loopback
    iface eth0 inet dhcp

    iface wlan0 inet dhcp
    wpa-ssid YourNetworkSSID
    wpa-psk YourPassword
