If you go into the device settings, there is a network diagnostics test that you can run to find out more information. Ensure that the network your device is attempting to connect to supports DHCP -- or it will be unable to communicate once you plug in. If you are using the wireless dongle, ensure your passphrase (if required for your wireless network ) is correctly entered, and if it is -- to rule out the dongle itself, plug a network cable direct from your HTS device into your Network Access Point / Router. One other thing to note would be that some access points (especially cable modems) remember the device that was plugged into them. If you simply unplugged one device, like a game console or computer and put that directly into your HTS box, you will likely have to power off -- and back on the access point / router / cable modem with neither device plugged into it. then once the network gateway is powered back on, plug your HTS into it.
