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.
Steve has a Security Camera DVR and he's used a splitter to watch it in several rooms using a balun, but he keeps losing the signal. Leo says that HDMI doesn't throw very far, and using a balun amplifies the signal and sends it over ethernet to the other side. The distance is still limited to around 200' and it could be that he's at the extreme edge of the range. Steve could go RF. The chat room says that using Cat6 Ethernet cables could make it that far, and at MonoPrice.com he could get an extender kit to around 328 feet.
