Yes, it's that simple. If you have an ethernet cable available that you can connect to your router then you're all set.
So, it turned out -- just plain normal. I ran a CAT5 line from my router to the HR21-PRO, and -- no problem; it just behaved normally, with the router's facilities assigning the I P address, etc.Stuart Sweet said:The information you speak of at the DIRECTV website refers to powerline adapters for people who don't have CAT5 at their DVR.
