First, make sure you have connected your device to the internet and checked for the latest updates for your device. Second, make sure you have followed your manual’s instruction regarding setup. Most devices must be connected to both the outlet and the device in order to get a signal since the antenna/receiver is built into the power cord. Also, some devices must be fully docked in order to work. Finally, try to expose the antenna to as much “sky” as possible and do not use a “splitter” device to share the power outlet with another device (like an iPod) as this may cause interference with the receiver.
