At Proshop we always have a wide range of different network cables in stock. We have many different colours and lengths.
A network cable can be used for a lot of things. If you have a router or NAS server, it is a necessity to have a LAN cable. If you want a better network when you play on your desktop, console or laptop, it would be a good idea to connect a network cable. If you are using an Apple TV or have a Smart TV, you can also get a better connection via cable. Most Wi-Fi printers currently work without cable, but some models still need a LAN cable.
