> Unfortunately cat6 can only handle about 10 Gbps

What is the main limitation for cables regarding transmission rates? Do we just need to move to fiber?

I was surprised recently looking into wifi options that apparently the new wifi 6 claims to handle 2400Mbps.

I assumed a wired connection would always trounce wireless (and I guess cat6 can do 4x that), but it seems like people are moving mostly to wireless setups. Is it solely because of the inconvenience of wiring things through a building?
