How to Connect a Desktop Computer to Wi-Fi via Your Phone: A Complete Guide

Desktop PCs rarely come with built-in Wi-Fi adapters, especially budget or older models. However, the need to connect to a wireless network can arise at any time: from installing drivers to online gaming or using cloud services. In such cases, a smartphone Android or iOS becomes a universal solution - it can distribute the Internet over USB, create access point or even transmit data through Bluetooth.

In this article, we'll cover all the current methods for connecting a PC to Wi-Fi via a phone, their pros and cons, and provide recommendations for troubleshooting common issues. We'll pay special attention to settings. Windows 10/11, since this is the OS most often used on desktop computers. If you have macOS or Linux — the principles remain the same, but the menu paths may differ.
