Computer broadband network speed direct connection optical cat fast, because more than a layer of equipment will be more than a data exchange and forwarding process, it will increase the time and network signal running time, so in order to obtain the best network speed direct connection optical cat is the fastest.
The computer network cable is fast, because the router has a certain delay, so the computer network cable directly connected to the optical cat will be faster, the router is only used to expand the connection port and wifi signal.
