Everywhere you go these days, data is whizzing through the airwaves.
While we use 4G and 5G data on our smartphones as we re driving or walking, WiFi still dominates in the home. And in coffee shops. And libraries. And airports. Thanks to the ubiquity of wireless routers and hotspots, just about any plain old wired internet connection faster and cheaper and without the limiting bandwidth caps of cellular data can be turned into a convenient WiFi zone.

Whether we install them ourselves or get them from our internet providers, most of us have WiFi routers in our homes. That can cause a couple of problems: One, wireless signals are operating on the same frequency and they can cause interference, especially if you re living in an apartment building. Two, without the proper security, someone could easily hop onto your wireless network.
