How to connect an all-in-one PC to Wi-Fi via a phone: 3 proven methods

Connecting your all-in-one PC to the internet via your smartphone is a versatile solution when you don't have a router or wired connection. This method is useful on a business trip, at the cottage, in a hotel, or even at home if your primary Wi-Fi is temporarily unavailable. Your smartphone can act as both a hotspot and a bridge, transmitting internet from your mobile network to your computer.

In this article we will look at three main connection methods: via mobile hotspot (Wi-Fi), by USB cable and through BluetoothEach has its own characteristics: for example, Wi-Fi provides the fastest speed but drains the phone's battery faster, while a USB connection is more stable but requires a cable. We'll also look at common errors (for example, when an all-in-one PC doesn't detect the phone's network) and provide recommendations for troubleshooting.

Important: If your all-in-one PC is running Windows 10/11 or macOS, and the phone is on Android 8+ or iOS 12+All the methods described will work. Older OS versions may require additional drivers or settings.

1. Preparing your phone and all-in-one PC before connecting

Before you begin setup, make sure both devices are ready to connect. This will eliminate most connection issues.

On the phone:

  • 📶 Check your mobile network signal strength. If the indicator shows 1-2 bars, your internet speed will be extremely slow. It's best to move closer to a window or use a 4G/5G network.
  • 🔋 Charge your phone to at least 50%. Sharing the internet via a hotspot drains the battery 2-3 times faster than usual.
  • 📱 Update your operating system. Android go to Settings → System → Software Update, on iPhone - V Settings → General → Software Update.

On the monoblock:

  • 🖥️ Make sure your Wi-Fi adapter is turned on. Windows Check the network indicator in the tray (the antenna icon). If it is crossed out, click Win + A and activate Wi-Fi.
  • 🔄 Restart your computer if you've previously had network connection issues. This will reset the network settings cache.
  • 🛡️ Temporarily disable your firewall or antivirus if they are blocking new connections.
⚠️ Note: If your all-in-one PC is connected to a corporate network via VPN, tethering from your phone may conflict with your company's security policies. In this case, use a USB connection.

There may be several reasons:

  • Data transfer is disabled on the phone (check the 3G/4G/5G indicator).
  • The operator blocks Internet distribution (applicable to some unlimited tariffs).
  • The network settings on the all-in-one PC are incorrectly configured (try resetting the TCP/IP settings using the command netsh int ip reset V Command line).
