Share PC Internet Wi-Fi with iPhone

This guide shows you how to turn your Windows laptop or Mac into a mobile hotspot so your iPhone can use the same internet connection. It’s useful when your home Wi-Fi is down, you’re on a wired connection, or you want to avoid using cellular data. You’ll need a PC with an active internet connection (Ethernet, Wi-Fi, or cellular) and an iPhone with Wi-Fi enabled.

What You’ll Need

A Windows laptop or Mac with internet access (via Ethernet, Wi-Fi, or a USB cellular modem).
An iPhone running iOS 13 or later (for Personal Hotspot compatibility).
Administrator rights on the PC (to change network settings).
Both devices should be within about 30 feet of each other for a stable signal.

Step-by-Step

On Windows 10 or 11

Open Settings: Click the Start button and select the gear icon (Settings), or press Windows + I.
Go to Network & Internet: In Settings, click “Network & Internet.”
Select Mobile hotspot: In the left sidebar, click “Mobile hotspot.” (On Windows 11, it may be under “Mobile hotspot” in the main list.)
Turn on the hotspot: Toggle the switch at the top to “On.” If it’s already on, turn it off and on again to refresh.
Choose your internet source: Under “Share my internet connection from,” select the connection that’s currently active (e.g., “Ethernet” or “Wi-Fi”).
Set the network name and password: Click “Edit” to change the network name (SSID) and password. Use a password of at least 8 characters. Write it down – you’ll need it on your iPhone.
Note the band: If you have a 5 GHz capable adapter, you can choose “2.4 GHz” for better range or “5 GHz” for faster speed. iPhones support both, but 2.4 GHz travels farther.
Connect your iPhone: On your iPhone, go to Settings > Wi-Fi, find the network name you just set, tap it, and enter the password.

On macOS (Ventura or later)

Open System Settings: Click the Apple menu and select “System Settings.”
Go to General > Sharing: In the sidebar, click “General,” then click “Sharing” on the right.
Enable Internet Sharing: Click the toggle next to “Internet Sharing.” If it’s already on, turn it off and on again.
Choose your internet source: In the “Share your connection from” dropdown, select the active connection (e.g., “Wi-Fi” or “Ethernet”).
Select how to share: Check the box next to “Wi-Fi” under “To computers using.”
Configure Wi-Fi options: Click the “Wi-Fi Options…” button. Set a network name (SSID), choose a channel (leave as default), and set a password (at least 8 characters). Click “OK.”
Start sharing: Click the toggle back on. You may see a warning that turning on Internet Sharing will stop your current network connection – this is normal if you’re sharing your Wi-Fi connection. Click “Start.”
Connect your iPhone: On your iPhone, go to Settings > Wi-Fi, select the network name, and enter the password.

Common Mistakes

Sharing the wrong connection: If your PC is connected to the internet via Wi-Fi, but you select “Ethernet” as the source, the hotspot won’t work. Always match the source to the active connection.
Password too short or simple: Some devices may fail to connect if the password is less than 8 characters. Use a mix of letters and numbers.
Forgetting to turn on the hotspot after a reboot: Windows and macOS often reset sharing settings after a restart. Re-enable the hotspot each time.
Using a 5 GHz band when the iPhone is far away: 5 GHz has shorter range. If the connection drops, switch to 2.4 GHz.
Not disabling VPN or proxy: A VPN on your PC can interfere with the shared connection. Temporarily turn it off.

Tips

Keep your PC plugged in: Sharing internet drains battery faster. Plug in the laptop to avoid shutdown.
Place the PC centrally: The closer your iPhone is to the PC, the better the signal and speed.
Use a unique network name: This avoids confusion if other nearby networks have similar names.
Check data usage: If your PC uses a metered connection (like a cellular USB modem), monitor data usage to avoid overage charges.
Update network drivers: On Windows, outdated Wi-Fi drivers can cause instability. Check for updates in Device Manager.

Troubleshooting

iPhone doesn’t see the network: Make sure the hotspot is on and broadcasting. On Windows, toggle the hotspot off and on. On Mac, turn off Internet Sharing and re-enable it. Also, check that the PC’s Wi-Fi adapter is not in “airplane mode.”

Connection drops frequently: Move closer to the PC. Switch the band from 5 GHz to 2.4 GHz (Windows) or change the channel (Mac). Restart both devices. Also, disable power-saving mode for the Wi-Fi adapter on Windows (Device Manager > Network adapters > your adapter > Properties > Power Management > uncheck “Allow the computer to turn off this device”).

iPhone connects but no internet: Check that the PC itself has internet access. If it does, try restarting the hotspot. On Windows, run the network troubleshooter (Settings > Network & Internet > Status > Network troubleshooter). On Mac, check that the source connection is correct in Sharing settings.

Hotspot turns off by itself: Some PCs have a setting to turn off the hotspot when no devices are connected. On Windows, go to Mobile hotspot settings and uncheck “When no devices are connected, automatically turn off.” On Mac, keep the System Settings window open – it may turn off if you close it.

Cannot edit network name/password: On Windows, you must be logged in as an administrator. On Mac, you may need to unlock the settings by clicking the lock icon and entering your password.

Frequently Asked Questions

Can I share a Wi-Fi connection that my PC is already using? Yes, both Windows and Mac allow sharing a Wi-Fi connection over a second Wi-Fi adapter (or the same one on some hardware). On Windows, select “Wi-Fi” as the source. On Mac, the same is possible, but it may require an additional Wi-Fi adapter if your Mac only has one.

Will this use my iPhone’s cellular data? No, the iPhone is using the PC’s internet connection. Your iPhone will show a Wi-Fi icon, not a cellular icon, and data usage on the iPhone will be zero.

Can I share a VPN connection from my PC? Yes, but the VPN must be configured to allow other devices to use it. Some VPN clients block sharing. Check your VPN settings or temporarily disable it.

Does this work with a Mac and an iPhone using the same Apple ID? Yes, but the hotspot method described here works independently of Apple ID. If you use the same Apple ID, you might also see the option to join the hotspot automatically via iCloud, but that uses the iPhone’s cellular data, not the PC’s internet.

Why is the speed slow? The speed depends on your PC’s internet connection, the Wi-Fi band, and distance. 2.4 GHz is slower but has better range; 5 GHz is faster but shorter range. Also, other devices on the same network can reduce speed.

Can I share internet from a PC that uses a USB cellular modem? Yes, as long as the modem is recognized as a network adapter. On Windows, select that adapter as the source. On Mac, it may appear as a separate interface.
