For all the greatness of Wi-Fi, wired ethernet is typically faster and more stable. In my new  house, I had CAT6 ran to every TV location to hardwire all of my Rokus. In one of the rooms, we decided that we wanted to swap the TV location to another part of the room.

I ordered a 45-foot roll of flat CAT6 cable. This allowed me to easily tuck it under the baseboards and carpet. Depending on your house setup, this could be used to run ethernet from one room to the next.

There are multiple sizes depending on your needs. Get it on Amazon for $11.
