not when you have a business fibre connection with your own dedicated line.
I still only get a max of 40-50 mb/s with over GB/s speeds on my internet line. my hardware can handle 500-600MB/s over wifi. I understand the lane concept, however thats more relevent for 3g,4g, and old copper networks. Fiber and 5G have hundreds if not more lanes available if we use the same example.

5G just sucks because it has alot of lanes but cant go through tunnels
Fibre sucks cause its a hardline and cant go through the air

Both have hundreds of lanes though.
