How does Wi-Fi work without an internet connection?
Wi-Fi works by using radio waves to transmit data between devices on a network. When a device connects to a Wi-Fi network, it sends a request to the network’s router, which then authenticates the device and assigns it an IP address. If there is no internet connection, the router can still assign an IP address to the device and allow it to communicate with other devices on the network. This allows devices to communicate with each other and share resources, even if they are not connected to the internet. The Wi-Fi network can be set up to use a static IP address or a dynamic IP address, depending on the needs of the network.
In a network without internet, the devices can communicate with each other using the IP addresses assigned by the router. This allows devices to share files, stream media, and communicate with each other, all without the need for an internet connection. The network can also be secured using standard Wi-Fi security protocols, such as WPA2, to protect the devices and data on the network. However, without an internet connection, the network is isolated and cannot communicate with devices or services outside of the local network. This can limit the functionality of the network, but it can still provide many useful features and capabilities for devices that are connected to it.
What are the limitations of using Wi-Fi without internet?
One of the main limitations of using Wi-Fi without internet is the lack of access to online resources and services.
