But i want network wall sockets in my room so i can plug the rj45 cable into them from my pc and laptop but what cables do i use from the hub to the wall socket? is it cat5. Also does the end of the cable coming from the wall socket to the 8 port hub have to be crimmed with a Rj45 connectors. thanks
