Q: How can you get WiFi without internet?

Absolutely!

A WiFi router, hot spot, or other device that provides a Wi-Fi signal for other devices to connect with, will do just that without an Internet connection. This can be done to create an ad-hoc local network for multiple people to play computer games or share data with each other. The only thing missing would be the ability to get on the Internet.

Technically, a Wi-Fi router is defined as:

  • Created a wireless network allowing X devices to communicate with each other
  • If an Internet connection is available, will link the two different networks (Wi-Fi and Internet) together, so that (baring firewall or other blockages) Internet activity can reach the users of the Wi-Fi network, and the users of the Wi-Fi network can reach the Internet.
