I don’t have enough ethernet ports on the back of my router so i recently bought an ethernet splitter. When it got here i plugged it in and it was working perfectly fine for my ps5 but my cat8 to my pc wouldn’t connect. I checked the splitter and it says cat7. Would i have to order a cat8 splitter for my cat8 cable to work or is there another solution?
A) I can guarantee you wasted money CAT8 cable for one.
B) You can’t split ethernet like you can a coax TV cable for example or even a phone line. You would need a splitter on both sides that would limit both connections to 100 megabits per second and you would still need an extra port on the the router or switch.
What you need is a network switch. It would plug into an available port on the router, and more devices can plug into it.
