Most people don't have the equivalent of home internet plumbing in general. They have a hole drilled into the wall (by the ISP) where the all-in-one modem-router-switch-wap sits on a shelf. There's probably a third party service to get ethernet run through your walls, and maybe even replace your all-in-one box with something good, but most people are just doing the equivalent of getting water straight out of the water company's tap with no plumbing.
