ok this is a stupid question but i really cant find the answer... i was wondering if there is such thing as an ethernet cord splitter... just a simple thing that makes one ethernet plug turn into 2 thats it no extra things but i have a direct connection out of the wall for ethernet and i have a modem plugged in but in order to get the TV to work i need another ethernet cable so i was just wondering if that is a real thing or if im screwed
