Marion's sister is heavily into gaming and wants to hardwire her PC to the network to get better gaming performance. Leo says that hardwiring is always going to be a bit faster than Wi-Fi because of wireless congestion. Leo says ideally, the best way to do this is to lay conduit from room to room and snake CAT6 ethernet all over the house. That requires opening the wall and is usually best when building a home. She also may need a switcher to handle the traffic around the house.
