Not to mention most ISP marketing is pretty loose in its terminology. Most if not all radio or tv ads these days seem to interchange internet and wifi as if they are one and the same on a daily basis.
ie. All ads stating something along the lines of "subscribe to whole home wifi for a low monthly fee."
I have too many conversations on both sides of the age gap trying to explain the difference between supplying your own router with its own wifi capabilities as opposed to a ISP modem/router combo.
