So I could have my laptop connected to the net as well as my xbox 360 I recently purchased an ethernet coupler, ethernet splitter and two ethernet 3 metre cables. There is a 30 m cable that runs along the outside of my house to the router. This cable comes into my room through the wall. I then attached the coupler and I plugged the splitter into the other end of that. Then I attached the two cables to the splitter, one going into my laptop and the other into my xbox. My laptop connection is working fine but my xbox one isn't, why?
