I have a pc and a ps4 right next to eachother and my ps4 runs off of wifi atm. i had to move my router away from the pc and ps4 because of remodeling and i now only have 1 ethernet cord running to my pc. i would like to hook my ps4 up to a line to improve connectivity. my problem is i dont know if having a splitter will cut my performance because 1 cord is handling the connection of 2 devices. help?
