How to Use Your Phone as a Wi-Fi Adapter: 3 Working Methods + Speed ​​Comparison

Modern smartphones have long ceased to be mere communication devices—they've become universal devices capable of replacing a whole host of gadgets. One of the most useful, yet little-known, scenarios is using a phone. as an external Wi-Fi adapter for a computer, laptop, or even a smart TV. This is especially useful when the built-in adapter on your PC is broken, the drivers won't install, or you want to connect to a 5 GHz network that your old network card doesn't support.

In this article we will look at all possible ways transform Android or iPhone into a full-fledged Wi-Fi module - from the classic Internet distribution via USB (USB-tethering) to advanced methods with a reverse hotspot. You'll learn which method provides the highest speed, how to bypass carrier restrictions on data sharing, and why it's sometimes better to use Bluetooth instead of a cable. And at the end, a comparison table of all the methods with their pros and cons.

Before you proceed with setup, please check two key points: first, make sure that your phone has mobile Internet is enabled (if you plan to distribute 4G/5G), and secondly, what's on the computer USB connection allowed (for the corresponding method). On Windows 10/11 And macOS Additional drivers are usually not required, but Linux Manual network configuration may be required.

1. USB ethering: the most stable connection method

Method USB-tethering (USB tethering) is the most reliable option to use your phone as a Wi-Fi adapter, especially if you need maximum speed and minimal delaysData is transmitted via a cable, eliminating signal loss like with wireless sharing. Suitable for gamers, streamers, or cloud users who require a stable connection.

To activate USB ethering on Android:

1. Connect your phone to your computer with the original USB cable (cheap cables may not support data transfer).
2. Open Settings → Network & Internet → Hotspot & Tethering (on some firmware versions the path may differ).
3. Activate the switch USB modem.
4. On the computer in Network connections a new device will appear - it is usually called Remote NDIS or USB Ethernet.

On iPhone (iOS) the process is a little different:

• 🔌 Connect your iPhone to your PC/Mac via Lightning or USB-C cable.
• 📱 On the menu Settings → General → Tethering turn on the option.
• 🖥️ On Mac, the connection will happen automatically, but on Windows, installation may be required iTunes (even if you don't use it) for drivers.

⚠️ Please note: Some operators (eg. Megaphone or Tele2) block USB ethernet on certain plans. If internet access isn't available, check your plan's terms or try alternative methods.

2. Sharing Wi-Fi from your phone: when you don't have a cable handy

If you don't have a USB cable or need to connect multiple devices at the same time (for example, a laptop and a tablet), you can use your phone as Wi-Fi hotspotThis method is universal, but has two drawbacks: higher ping (delay) and limited speed due to interference in the air. But it doesn't require wires and works even with devices without USB ports (for example, Apple TV or Amazon Fire Stick).

Instructions for Android:

1. Open Settings → Network & Internet → Hotspot & Tethering.
2. Select Wi-Fi hotspot (or Mobile hotspot on Samsung).
3. Set up a network name (SSID) and password (we recommend using WPA2-PSK).
4. Activate the access point and connect to it from your computer.

On iPhone:

• 📶 Go to Settings → Tethering.
• 🔒 Turn on Allow others and set a password (minimum 8 characters).
• 🖥️ On your PC, find a new Wi-Fi network named iPhone [your name].

The speed in this mode depends on Wi-Fi standard your phone:

• 📱 Wi-Fi 4 (802.11n) — up to 150 Mbit/s (old smartphones).
• 📱 Wi-Fi 5 (802.11ac) — up to 866 Mbps (most flagships 2018–2022).
• 📱 Wi-Fi 6 (802.11ax) — up to 2 Gbit/s (iPhone 11/12/13/14, Samsung Galaxy S20+ and newer).

⚠️ Please note: When using Wi-Fi, your phone consumes a lot of power. If your battery is low, connect it to a charger; otherwise, your phone may shut down after 1–2 hours.

3. Bluetooth tethering: slow but secure

Connection via Bluetooth — the most discreet and energy-efficient way to use your phone as a Wi-Fi adapter. It's suitable for small data transfers (email, instant messaging, web surfing), but not suitable for 4K video, online gaming, or file downloadsThe main advantage is minimal battery consumption and work even if the USB port is busy or broken.

How to set up on Android:

1. Turn on Bluetooth on the phone and computer.
2. Pair your devices (on PC: Start → Settings → Devices → Bluetooth).
3. On your phone, go to Settings → Network & Internet → Hotspot & Tethering.
4. Activate Bluetooth modem.

On iPhone:

• 🔵 Turn on Bluetooth V Control center.
• 🖥️ On your Mac or PC, add your iPhone to the list of trusted devices.
• 📱 Return to Settings → Tethering and enable the option.

Speed Bluetooth 4.0–5.0 rarely exceeds 3–5 Mbps, A Bluetooth 5.2 (in new flagships) can give up to 20–25 MbpsThis is enough for:

• 📧 Checking email and instant messaging apps.
• 🌐 Easy surfing (no HD video).
• 🎵 Music streaming (but not without loss of quality).

4. Reverse Tethering: Use your phone as a Wi-Fi receiver

All previous methods assumed that the phone distributes Internet. But what if you want the opposite—to use your smartphone as Wi-Fi adapter for PCconnected to another network? For example, when you only have Ethernet on the computer, but you need to go online through 5G phone. There is a phone for this. reverse tethering (Reverse Tethering).

This method is more difficult to set up and requires root rights on Android or jailbreak on iPhoneWe will consider a simplified version for Android without root access:

1. Install the application on your phone ClockworkMod Tether (there is a free version).
2. Connect your phone to your PC via USB and run the program.
3. In the settings, select Reverse Tethering and specify the network interface.
4. On the computer in Network connections A new connection will appear - use it as your primary connection.

For iPhone Reverse tethering is only possible with a jailbreak and a tweak installed. MyWi or TetherMeThis method is not feasible without jailbreaking iOS.

⚠️ Note: Reverse tethering may violate some carriers' mobile data terms and conditions. If your traffic is suddenly blocked, disable this feature.

Why do operators block internet tethering?

Many mobile plans prohibit using a phone as a modem, as this creates additional network load. Carriers detect tethering based on TTL packets or the user agent, and can then limit speed or block access.

5. Comparison of all methods: speed, stability, energy consumption

To choose the best method, please refer to this table. We have tested all methods on Samsung Galaxy S22 Ultra (Android 13) and iPhone 13 Pro (iOS 16) with network connection 5G operator MTS:

From the table it is clear that USB-tethering — the best choice for most tasks if mobility is not required. Wi-Fi hotspot It's convenient for connecting multiple gadgets, but it lacks speed and stability. Bluetooth should only be used in extreme cases when other methods are not available.

6. Common problems and how to solve them

Even with proper setup, errors can still occur. Here are the most common ones and how to fix them:

• 🔌 "USB device not recognized" (Windows):
  

  Check the cable, try another USB port (preferably USB 3.0). If this doesn't help, install the drivers for your phone model from the manufacturer's website (for example, Samsung Smart Switch for devices Samsung).

• 📶 "No internet connection" when sharing Wi-Fi:
  

  Make sure your phone has mobile internet enabled. If you are using dual-SIM, check that the access point is linked to the correct SIM card. iPhone resetting network settings may help (Settings → General → Move or reset).

• 🔄 "The Internet works for 5 minutes and then disconnects.":
  

  This is usually due to operator restrictions. Try changing them. APN (access point) in your mobile network settings or use a VPN on your phone (for example, 1.1.1.1 from Cloudflare).

• 🔋 "The phone gets very hot and drains its battery.":
  

  When sharing Wi-Fi, disable unnecessary background apps, reduce screen brightness, and activate power saving mode. USB-tethering Use the original charger.

7. Security: How to protect your connection

Using your phone as a Wi-Fi adapter creates potential vulnerabilities, especially if you're connecting to public networks or sharing internet in crowded areas. Follow these guidelines to minimize the risks:

• 🔐 Always use a complex password for the access point (at least 12 characters with numbers and special characters). Avoid standard passwords like 12345678 or password.
• 🛡️ Turn off distribution, when it's not needed. A constantly active hotspot makes your phone visible to vulnerability scanners.
• 🌐 Set up a VPN on your phone, if you connect to untrusted networks. This will protect your traffic from interception (we recommend ProtonVPN or Windscribe).
• 📵 Disable automatic connection to open Wi-Fi networks in your phone settings.

On Android additionally possible:

• Prevent unknown devices from connecting to your access point (there is a list of connected devices in the access point settings).
• Use apps like NetGuard to control application access to the Internet.

On iPhone:

• Activate the option Ask before connecting in the settings Modem mode.
• Check the list of connected devices regularly. Settings → Tethering.

⚠️ Warning: If you share the Internet in a public place (cafe, airport), attackers may try to connect to your access point to carry out an attack MITM (traffic interception). Always use HTTPS and avoid entering passwords on unfamiliar websites.
