Question: is my wifi 2.4 or 5 ghz?
Answer: The best way is to look up your router's model on the manufacturer's website. ... This is a good sign that you have a dual band router. Each router will name the 2.4 GHz and 5 GHz bands differently, but you can generally tell just by looking. For instance, the 5 GHz network may have 5, 5G, or 5GHz as part of its name.
