What is the difference between internet and WiFi?
Comparison between WiFi and Internet
WiFi is a wireless network to connect nearby devices with each other and share the Internet via hotspots. Internet is a global network of networks where computers communicate with each other via Internet Protocol.
What is WiFi and how do I use it?
A wireless or WiFi network uses a radio frequency signal instead of wires to connect your devices - such as computers, printers and smartphones - to the Internet and each other. The WiFi signal can be picked up by any wireless-capable device such as a laptop or tablet within a certain distance in all directions.
Can you have WiFi without internet?
You Can Be Connected To WiFi, But Not The Internet
The radio tower that is broadcasting its network throughout your home will not stop broadcasting its signal if the internet is no longer being fed to it.
Where does WiFi signal come from?
Your WiFi signal originates from where the WiFi connection is established in your home— the wireless router. For signal, wireless routers use a certain frequency band, either the 2.4 GHz band or the 5 GHz band.
