Ethernet connection - DirecTV

I like everybody else cant stay connected to the internet and my on demand is basically useless. Takes sometimes 12 hours to download a one hour show. But everything else such as Amazon or net flix will load in minutes. I was thinking of ethernet connection to main box from my Uverse router 5268AC. Is this a possible solution? If so how do I do it? Do i run cable from one of the open ethernet ports to the HR54_200 box?
Any help would be appreciated.
