That's not at all normal. They aren't supposed to do that from anything I have ever seen or read. They are supposed to run coax to the spot and then use the deca to connect to your router with a short Ethernet cable. Did you already have the cable or something? Pay extra maybe? Customer installer? Just never heard of this from a normal DIRECTV installer, which is why peds was likely saying what he said. Very unusual.
And I assume this 50ft was from your router to the hr44 where it then plugged into your hr44 to give you Internet access, yes?
Right on! DirecTV DOES NOT provide Ethernet cable to the techs. so if the tech did it for you it must have been a "on the side" kind of thing
