Full origin of Wi-Fi →Frequently Asked Questions
What is the difference between Wi-Fi and the internet?
Wi-Fi is only the last, wireless step between your device and a router in the building. The internet is the global network your router reaches through a broadband line, fibre or mobile connection. That is why you can be connected to Wi-Fi and still have no internet access, if the line beyond the router is down.
Is Wi-Fi the same as broadband?
No. Broadband is the service that brings a connection into the property, usually over a cable or fibre line. Wi-Fi is the wireless method of sharing that connection with devices inside the property.
What do 2.4 GHz and 5 GHz mean on a Wi-Fi network?
They are two different radio frequency bands a router can use. The 2.4 GHz band generally travels further and passes through walls more easily, while the 5 GHz band typically carries more data over shorter distances. Many routers offer both.
