How to connect a desktop computer to Wi-Fi from your phone: all the working methods

Connecting a desktop PC to the internet via a smartphone is a challenge faced by users without a router, when moving, or if their primary equipment breaks down. In 2026, this process became easier thanks to improved features. mobile hotspot V Android 14+ And iOS 17+, but nuances remain: from operator restrictions to the specifics of PC network adapters. This article covers all relevant methods—from standard Wi-Fi sharing to hidden USB connection features and Bluetooth bridges.

We tested each method on devices with Windows 10/11 And Linux (Ubuntu 24.04), taking into account common issues such as missing Wi-Fi adapter drivers, carrier blocking data distribution, or low connection speeds. Particular attention was paid alternative solutions for PCs without a built-in Wi-Fi module - using external adapters and even Ethernet cable (yes, it is possible!).

Important: If your computer does not see the networks distributed by the phone, in 90% of cases the problem lies in network adapter power saving settings or outdated drivers. We'll show you how to fix this without calling a service center.

1. Preparation: what you need to connect

Before you share your phone's internet connection, check four key components:

• 📱 Smartphone with function support Access point (available on all devices with Android 6.0+ And iOS 12+). The exception is some budget models with custom firmware.
• 🖥️ Desktop PC with a Wi-Fi adapter (built-in or external). If you don't have one, you'll need one. USB Wi-Fi dongle (from 300 ₽) or Bluetooth adapter 4.0+.
• 🔋 Charging your phone: Sharing your internet connection drains your battery 2-3 times faster. Connect your phone to the network or use Power Bank.
• 📶 Stable mobile signal: 4G/5G with a reception level of at least -90 dBm (checked in Settings → About phone → SIM card status). If the signal is weak, the speed will drop to 1–2 Mbps.

For Windows additionally check:

• 🔧 Wi-Fi adapter driver (update via Device Manager → Network Adapters).
• ⚡ Adapter power saving mode (must be disabled in Adapter Properties → Power Management).

Critical remark: some operators (eg Tele2 or Yota) block internet tethering on plans without the "Modem" option. In this case, you'll have to use workarounds—for example, USB connection or VPN tunneling (we will discuss this below).
