Have you tried setting the receiver & router up using the instructions
here? Click on "Home Network" on the left, then "How to?" on the right to see:
1. Verify current subscription to a broadband Internet service. No dial-up service.
2. Verify a correct home network is set up by accessing the Internet using the existing home computer.
3. Connect the receiver to the home network using the appropriate existing home network equipment.
4. In the receiver's Installation menu, select Broadband Setup and then Network Setup.
5. If the IP Address lists all 0's, select Reset Connection. If the IP Address is listed, continue.
6. If the Connection Status is 'Not Connected', troubleshoot the home network. If the Connection Status is 'Connected Online', continue.
7. In the receiver's Setup menu, select Diagnostics and then Connection.
8. Installation is complete. Exit menus.
NOTE: If you click on " Home Network Install Guide" you will download a pdf that should help a great deal.
