Although you can't split an RJ45 connection, commonly known as an Ethernet connection, as easily as a cable wire, specialised devices are available to ensure that the RJ45 cable's parameters are maintained for proper operation. Switches and active splitters take a single Ethernet lead and can output as many additional leads as the device supports.

  1. 1

    Push the Ethernet cable leading from the gateway or modem into the switch, router or hub input jack.

  2. 2

    Insert additional Ethernet cables from the individual outputs as needed into the output jacks on the routing device.

  3. 3

    Route the Ethernet cables as required to the individual networked devices, such as desktops, laptops and gaming consoles. Plug the Ethernet cables into the corresponding jacks on these devices.

Tips and warnings

  • Use a wireless router to increase your networking outputs. Although most routers have four to six wired outputs, there is in theory no limit to the number of wireless devices the router will support.
