"WiFi 5G" is one of the most searched — and most misunderstood — phrases in computing. It can mean one of two very different things: the 5 GHz radio band used by dual-band Wi-Fi routers and access points, or 5G cellular (5G NR), the mobile broadband standard offered by telecom operators. A Wi-Fi adapter that supports "5G" almost always refers to the 5 GHz frequency band, not to 5G mobile networks. Because the two technologies use different radios, antennas and certifications, the cost of adding either one to a computer depends entirely on which of the two you actually need.
