How to connect the internal and external network splitters
This diagram will show you how to properly connect the splitter to your wall outlet, router, or any other network device. An Ethernet splitter doesn't actually split a single Ethernet connection to provide separate internet access to two devices. However, connecting. When you need to connect multiple wired devices like computers, printers, and IP phones, but only have one Ethernet wall port, using an Ethernet splitter or network switch can expand your connectivity without rewiring. It simply divides signal pairs.
