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?
Return it. Buy a Cat6 cable and an unmanaged switch. Ethernet splitters are a scam, and Cat 8 is a cable for special applications in big data centres and nothing you own can take advantage of the ways it differs from regular Cat 6 unless you’re Bill Gates.
Nobody actually uses Cat8, not even datacenters (we just use fiber or DAC). The wiki article says it was designed for it, but it’s less reliable, has more overhead, and is more power hungry, so it never caught on.
