1) Use either WEP (Wired Equivalency Protocol) or WPA (Wi-Fi Protected Access).

2) Make sure that both your router or access point and all of the clients on your network share the same encryption key. Write down the key and put it in a safe place.

The Belkin TuneStage for iPod lets you stream music wirelessly from your iPod to your stereo from up to 33 feet away, via Bluetooth 1.2. The compact base station plugs into your home stereo’s RCA inputs or 3.5mm minijack, and the small transmitter plugs into iPods that have a fourpin remote connector next to the headphone jack (that, unfortunately, excludes the iPod nano and shuffle).


Setup takes less than a minute, and the sound quality is as good as we expected, considering the Bluetooth compression. The transmitter limits the iPod’s battery life to around 10.5 hours.
