Share Internet Between Windows PC and iPhone/Android

This guide shows you how to share an internet connection between a Windows computer and an iPhone or Android phone in both directions. You’ll learn how to turn your PC into a Wi‑Fi hotspot for your phone, and how to use your phone’s mobile data to get your PC online via USB tethering or a personal hotspot. No special software is needed—just the built‑in tools on Windows and your phone.

What You’ll Need

A Windows PC (Windows 10 or 11) with a working internet connection (Ethernet, Wi‑Fi, or cellular dongle).
An iPhone (iOS 13 or later) or Android phone (Android 8 or later) with the latest system updates.
A USB cable that supports data transfer (not charge‑only) for USB tethering.
If you want to share your PC’s internet over Wi‑Fi, your PC must have a Wi‑Fi adapter that supports hosted networks (most laptops do).
If you want to share your phone’s internet, you need an active mobile data plan on the phone.

Step-by-Step

Part 1: Share Internet from Windows PC to iPhone/Android (PC as Hotspot)

Open Windows Settings. Press Windows + I and go to Network & Internet > Mobile hotspot.
Turn on the Mobile hotspot toggle. Windows will show a network name (SSID) and password. You can edit these by clicking Edit—choose a name and a strong password (at least 8 characters).
Select the internet source. Under “Share my internet connection from,” choose the adapter that’s currently connected to the internet (e.g., “Ethernet” or “Wi‑Fi”). If you’re connected via Wi‑Fi and your PC’s Wi‑Fi adapter can’t broadcast a hotspot simultaneously, Windows will warn you—you may need to use Ethernet or a USB cellular dongle instead.
Connect your phone. On your iPhone or Android, go to Wi‑Fi settings, find the network name you set, tap it, and enter the password.
Verify the connection. Once connected, your phone should show a Wi‑Fi icon. Open a browser to confirm you have internet access.

Part 2: Share Internet from iPhone/Android to Windows PC (Phone as Hotspot)

Using Wi‑Fi Hotspot

On your phone, enable the personal hotspot.
- iPhone: Go to Settings > Personal Hotspot and turn on “Allow Others to Join.” Note the Wi‑Fi password shown.
- Android: Go to Settings > Network & internet > Hotspot & tethering > Wi‑Fi hotspot and turn it on. Set a name and password if needed.
On your Windows PC, connect to the hotspot. Click the Wi‑Fi icon in the system tray, select your phone’s hotspot name, and enter the password.
Confirm internet access. Once connected, the Wi‑Fi icon will show full bars. Open a browser to test.

Using USB Tethering (more stable, charges your phone)

Connect your phone to the PC with a USB data cable.
Enable USB tethering.
- iPhone: Go to Settings > Personal Hotspot and turn on “Allow Others to Join”. If you see a “Trust This Computer?” prompt on the iPhone, tap Trust.
- Android: Go to Settings > Network & internet > Hotspot & tethering and toggle on USB tethering.
Windows will automatically detect the new network. It may take a few seconds. You should see a new network adapter in the system tray (wired icon). If prompted, select “Public network.”
Test the connection. Open a browser—if the page loads, you’re online.

Common Mistakes

Using a charge-only USB cable. Many cables are for charging only and lack data wires. Use a cable that you know transfers files.
PC hotspot not appearing on phone. This often happens when the PC’s Wi‑Fi adapter doesn’t support hosted networks, or when the PC is already using Wi‑Fi to connect to the internet. Check if the hotspot toggle turns off automatically.
Entering the wrong password. The password is case‑sensitive. Double‑check the exact characters, especially if you set a custom one.
Mobile data is off on the phone. If you’re sharing your phone’s internet, make sure mobile data is enabled and you’re not in airplane mode.
iPhone “Personal Hotspot” greyed out. This happens if Wi‑Fi and Bluetooth are both off, or if the carrier doesn’t allow tethering. Turn on Wi‑Fi and Bluetooth, or check with your carrier.

Tips

USB tethering is faster and more stable than Wi‑Fi hotspot, and it charges your phone at the same time. Use it when possible.
Set a strong, unique password for your PC hotspot to prevent unauthorized access.
If your PC hotspot keeps dropping, update your Wi‑Fi adapter driver from the manufacturer’s website (not just Windows Update).
On Android, you can set the hotspot to automatically turn off when no devices are connected to save battery.
If you’re sharing a metered PC connection, remember that phone apps may use a lot of data. Set your phone to “Data Saver” mode if needed.

Troubleshooting

Phone connects to PC hotspot but no internet. Go to Network & Internet > Mobile hotspot and check the “Share my internet connection from” setting. Try switching it to a different adapter (e.g., from Ethernet to Wi‑Fi). Also restart the hotspot toggle.
PC doesn’t see the phone’s USB tethering. Unplug the USB cable, restart both devices, and reconnect. On Windows, go to Device Manager and look for any yellow warning icons under “Network adapters” or “Universal Serial Bus controllers.” Update the drivers if needed.
iPhone tethering not working on Windows. Make sure you’ve tapped “Trust” on the iPhone when prompted. Also try a different USB port (preferably a USB 3.0 port directly on the motherboard).
Android USB tethering greyed out. This can happen if the phone is in “Charging only” mode. Swipe down from the top and change the USB mode to “File Transfer” or “MIDI” (the exact option varies by brand).
Hotspot works but is very slow. Move closer to the device providing the signal, or switch to USB tethering. Also check that you’re not in a low‑signal area for mobile data.
Windows shows “No internet, secured” on the hotspot. This usually means the PC’s internet source is not being shared properly. Restart the “Internet Connection Sharing (ICS)” service: press Win + R, type services.msc, find “Internet Connection Sharing,” right‑click and select Restart.

Frequently Asked Questions

Can I share my PC’s internet with a phone if the PC is connected via Wi‑Fi?

Yes, but only if your Wi‑Fi adapter supports “hosted network” mode. Many laptops do, but some adapters don’t. If the hotspot toggle turns off when you try to enable it, your adapter likely lacks this feature. A USB Wi‑Fi dongle can help.

Does USB tethering work with iPhones on Windows?

Yes, since iOS 13, iPhones support USB tethering to Windows without iTunes. You just need to trust the computer and enable Personal Hotspot. Older iOS versions may require iTunes to be installed.

Will sharing my phone’s internet use a lot of data?

It uses the same mobile data as if you were browsing on the phone. Heavy activities like video streaming or large downloads can quickly consume your data allowance. Keep an eye on your data usage in your phone’s settings.

Is it safe to use a public Wi‑Fi hotspot on my PC?

If you’re connecting to a public hotspot, use a VPN to encrypt your traffic. When you share your own hotspot, always use a strong password and avoid sharing sensitive information.

Can I share my PC’s internet with multiple phones at once?

Yes, the Windows Mobile hotspot supports up to 8 devices at the same time. However, performance may degrade if many devices are active simultaneously.

Why does my iPhone’s Personal Hotspot option disappear?

This can happen if your carrier doesn’t support tethering on your plan, or if Wi‑Fi and Bluetooth are both off. Try toggling Wi‑Fi and Bluetooth on, then restart the phone. If it still doesn’t appear, contact your carrier.

General steps for current mainstream versions; menus can differ by device and version. See the disclaimer or report an error.
