Sharing a Single Internet Connection Among Multiple Computers Using Wi-Fi: A Comprehensive Guide

Many users find themselves in situations where multiple computers need to share a single internet connection, but they do not want to invest in additional hardware or a router. This can be achieved through various built-in features available in operating systems like Windows, macOS, and Linux. This guide will walk you through the process of sharing an internet connection via Wi-Fi without any router or hardware changes.

Windows 10 and Later

Enable Internet Connection Sharing:

Ensure one computer is connected to the internet via Ethernet or another method. Go to Control Panel Network and Sharing Center Change adapter settings. Right-click the connection that has internet access and select Properties. Go to the Sharing tab and check Allow other network users to connect through this computer’s Internet connection. Choose the Wi-Fi connection from the dropdown if prompted.

Set Up Wi-Fi Hotspot:

You can use the built-in Mobile Hotspot feature available in Windows 10 and later to share the internet connection over Wi-Fi. Go to Settings Network Internet Mobile hotspot and toggle it on.

macOS (10.11 or Later)

Enable Internet Sharing:

Go to System Preferences Sharing. Check the box next to Internet Sharing. Select the source of your internet connection, such as Ethernet, in the Wi-Fi section. Click Wi-Fi Options to configure the network name and password. Finally, check the box next to Internet Sharing to enable it.

Linux

Set Up Hotspot:

Open the terminal and use nmcli to create a Wi-Fi hotspot, or utilize the network settings GUI to share the internet connection. You might need to install additional packages depending on your distribution.

Considerations

Performance: The performance may not be as good as using a dedicated router, especially with multiple devices connected.

Range: The range of the connection will depend on the computer's Wi-Fi adapter.

Security: Ensure you set a strong password for the shared connection to prevent unauthorized access.

This setup allows multiple devices to connect to the internet through the computer acting as a hotspot without needing additional hardware like a router. It's a practical and cost-effective solution for environments where sharing a single internet connection is required.
