I'm on coaxial, for my pc (if I understood) and only use wifi for my cell, when I'm in bed...
I prefer, définitivement, to be on a cable than on air...

BNC connectors....

The first Ethernet I built was on coax.

Even the big thick yellow "backbone" cable with vampire taps! (I never actually worked directly on a true backbone cable myself and have never installed a tap, though the ones I did see were still in production use)
