HR24-500 connect to internet

I use to have the Whole-Home DVR service but decided I did not use it enough to warrant the monthly charge. I discontinued the service and I now whatn to connect the HR24-500 I have to the internet.  What do I have to do to accomplish this? I have tried to connect an ethernet cable to it from my powerline source but I get an error 13. I am thinking this may have something to do with the switch they installed for the Whole-Home DVR. How to I get my internet connection to work?
