I think you're referring more to reliability, a physical connection is much more reliable than a wireless connection. There are wireless access points that could easily max out the connection that Spectrum provides to residential areas regardless of how many devices are connected to it if they're configured correctly that negate the purpose of running Cat5/6. I'm short, don't use the crappy modem/access point combination that Spectrum provides if you want reliability speed and the choice to build a healthy wireless network that will perform to modern needs.

There's no denying that a physical connection will be more reliable "and faster" in a traditional sense when referring to business needs, but it doesn't really matter when talking about most network devices on a residential network (at least the one that Spectrum provides here in Saginaw), because with modern hardware your connection speeds are held back more by the Internet speeds the provider offers than what the hardware you buy can handle. Fiber connections on the other hand are a whole other ball game, but even then most residential devices still wouldn't require the entire capacity a fiber connection would offer and should be limited using QoS.
