Kristen, Chadt4141 is correct. The Hopper bridges the Internet to the Joey's. To set this up, you would press the Home/Menu button on your Hopper remote three times, scroll down to "Network", then select "Internet Settings", then "Advanced" at the top right of the screen, then switch Bridging to "on". Once you do this, then you will see a message indicating the configuration was successful and you would not have Internet access at the linked Joeys.
