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.
Before you begin, check two key points: availability of mobile Internet on your phone (or connect to another Wi-Fi network if you plan to rebroadcast it) and sufficient battery chargeInternet sharing consumes a lot of energy, so it's best to connect your smartphone to a charger when using it for long periods of time.
1. Internet sharing via USB (USB tethering)
The most reliable and energy-efficient way is to connect your phone to your PC via USB cableIt provides a stable connection, minimal latency, and requires no additional adapters. It's compatible with all modern smartphones. Android 6.0+ And iPhone with iOS 12+.
To activate USB modem, follow these steps:

device Manager(chapterNetwork adapters).
☑️ Checking the USB modem
⚠️ Attention: On iPhone USB tethering may not work if the computer has not been previously authorized in iTunes or Finder (on macOS Catalina and newer). In this case, preliminary synchronization will be required.
2. Wi-Fi access point (mobile hotspot)
If your PC is equipped with a Wi-Fi adapter (built-in or external), the easiest way to create access point on your phone. This method is convenient for temporary connections, but it drains the battery faster than USB.
Instructions for Android:
- Open
Settings → Network & Internet → Hotspot & tethering → Wi-Fi hotspot. - Set up a network name (
SSID), password (minimum 8 characters) and select range2.4 GHzor5 GHz(the latter is faster, but has a shorter range). - Activate the access point and connect to it from your PC as you would to a regular Wi-Fi network.
For iPhone:
- Go to
Settings → Modem Mode. - Turn on the slider
Allow others. - The default password can be found in this same menu (or changed).
| Parameter | Android | iPhone |
|---|---|---|
| Max. number of devices | 10 | 5 |
| 5 GHz support | Yes (starting with Android 10) | Yes (iPhone 12 and later) |
| Auto power off | After 5-10 minutes without connections | After 1 minute (configurable) |
| Energy consumption | High | Average |
If the PC does not see the access point:
- 📶 Make sure your phone has mobile internet enabled (or is connected to another Wi-Fi network for repeating).
- 🔄 Restart the access point and refresh the list of networks on your PC (
Win + A → Wi-Fi). - 🛡️ Temporarily disable your antivirus or firewall—they may be blocking the connection.
3. Connecting via Bluetooth
