Hi guys and gals, I wired cat5e throughout my house from my high speed router closet installed by my ISP. Everything works just fine except one of the rooms I replaced a monitor with a smart tv. I only had a single rj45 jack in that room so I wired together a splitter. I tested the splitter and had lan/internet in and out of each side individually. When I hook it to the wall and try to plug in my computer lan card and then the back of the smart tv I loose internet on both of them, what am I missing? I even bought a splitter and it does the same thing, will work with 1 of the 2 plugged in but as soon as I plug in both I lose internet .
