WiFi Analyzer is a great application to install on your DroidBOX, as it helps you to find the best WiFi channel to set on your modem/router, great if neighbour's WiFi networks are causing interference and problems with signal levels.
Some network hardware (modems/routers/access points) will attempt to automatically select the best WiFi channel for you, however you can find this does not give the best coverage in the most important areas to you, so double check with this great app!
