How to Share Internet via Wi-Fi in Windows 10: A Step-by-Step Guide with Pictures and Videos

Turn your laptop or computer into a running computer Windows 10 into a full-fledged access point Wi-Fi It's easier than it seems. This feature is useful when you don't have a router handy but need to share internet with a smartphone, tablet, or a second computer. For example, at a hotel with a wired connection, at a dacha with a USB modem, or when your main router suddenly breaks down.

In this article we will look at all working methods Internet distribution via Wi-Fi V Windows 10 — from built-in tools to third-party utilities. You'll learn which method is the fastest, which is the most reliable, and how to avoid common mistakes like no network or limited access. And also, how to share the internet even if you don't have The "Mobile Hotspot" button is missing in the settings. (This problem occurs on 10% of devices with non-original drivers).

First, decide which internet source you will be distributing:

  • 🌐 Cable connection (Ethernet) is the most stable option for distributing to multiple devices.
  • 📶 3G/4G modem (USB) - suitable for the dacha or for travel, but the speed will depend on the operator's coverage.
  • 🔄 Other Wi-Fi — if you are connected to one network but want to create a second one (for example, for guest access).

Regardless of the source you choose, all the methods in this article work equally well. The main thing is that your Wi-Fi adapter supported the regime Hosted Network (this is checked automatically when the distribution starts).

📊 Which Wi-Fi sharing method do you use most often?
Built-in mobile hotspot
Command line
Third-party programs (Connectify, MyPublicWiFi)
I never gave it away

1. The Easiest Way: Windows 10 Mobile Hotspot

Built-in function Mobile Hotspot appeared in Windows 10 versions 1607 and has since become the primary tool for internet distribution. Its main advantages:

  • ⚡ Does not require command line — everything is configured in the graphical interface.
  • 🔄 Automatic control — you can limit the number of connected devices.
  • 🛡️ Password protection — the network is created with encryption WPA2-PSK (like modern routers).

To enable hotspot, follow these steps:

  1. Open Start → Settings → Network & Internet → Mobile hotspot.
  2. In the drop-down menu "Sharing" select the connection through which you receive the Internet (for example, Ethernet or Local Area Network Connection*).
  3. Click "Change" next to the network name and password fields to set your parameters (the password must be at least 8 characters long).
  4. Move the slider Allow use of my internet connection in position On.

Done! Other devices can now connect to your network. The access point name will be displayed as {Computer_name} {random_numbers}, unless you have changed it manually.

⚠️ Attention: If the internet connection disappears on the main device after enabling the hotspot, check your firewall settings. Sometimes Windows Defender Blocks connection sharing. Solution: Temporarily disable your firewall or add a network exception.

☑️ Check before launching a hotspot

Completed: 0 / 4

2. Sharing Wi-Fi via the command line (for advanced users)

If in your version Windows 10 There is no "Mobile hotspot" tab (this happens after updates or when using pirated builds), you can start distribution through command lineThis method is universal and works on all versions of the system, including Windows 10 LTSC.

The instructions consist of two stages: creating a virtual network And Internet sharing permission.

Step 1: Starting a hosted network

Open the command prompt as administrator (click Win + X and select the appropriate item). Then enter the following commands in sequence:

netsh wlan set hostednetwork mode=allow ssid="MyWiFi" key="12345678" keyUsage=persistent

netsh wlan start hostednetwork

Where:

  • MyWiFi — the name of your network (you can replace it with anything).
  • 12345678 — password (minimum 8 characters, case sensitive).

After executing the second command, the following message should appear: "The hosted network has started."If you see an error instead "Failed to start hosted network", Means:

  • 🔌 The Wi-Fi adapter does not support the mode Hosted Network (check the adapter model in Device Manager).
  • 🚫 The driver is outdated or corrupted. (update it through device Manager or the manufacturer's website).
  • 🛠️ Service Autoconfig disabled (turn it on through services.msc).

Step 2: Permission to share your internet connection

Now you need to "allow" your connection (for example, Ethernet) share the Internet with the created network. To do this:

  1. Open Control Panel → Network and Internet → Network and Sharing Center.
  2. Click on the active connection (for example, Ethernet).
  3. In the window that opens, click Properties → Access.
  4. Check the box Allow other network users to connect to your Internet connection.
  5. In the drop-down menu, select the network you created (it will be called "Local Area Connection* X", where X is a number).

After applying the settings, restart your computer. Devices will now be able to connect to your network. MyWiFi.

How do I check if my adapter supports Hosted Network mode?

Open command prompt and type: netsh wlan show drivers

In the results, look for the line "Hosted Network Support." If it says "Yes," your adapter supports sharing.

3. Sharing Wi-Fi through third-party programs: Connectify, MyPublicWiFi, and others

If built-in tools Windows 10 don't work or you need advanced features (e.g. traffic control, device blacklist, ad blocker), you can use specialized programsThey are paid, but usually have a free trial period.

Let's compare the most popular utilities:

Program Free version Max devices Additional functions Cons
Connectify Hotspot Yes (with limitations) 5 Ad blocking, traffic monitoring In the free version it turns off after 30 minutes.
MyPublicWiFi Yes 10 Connection log, autostart The interface is in English, there is no technical support.
Virtual Router Plus Yes Unlimited Simple interface, portable version Not updated since 2016
Baidu WiFi Hotspot Yes 8 5G support, speed analytics Chinese software, potential privacy issues

We recommend MyPublicWiFi For most users, it's free, supports Russian (after installing the language pack), and has no time limit. You can download it from official website.

Setup instructions MyPublicWiFi:

    2. Find in the list Network adapters and delete yours Wi-Fi adapter (right click → "Remove device").
    3. Restart your computer - Windows will automatically reinstall the driver.
  3. Enable the feature via the registry (if the cause is group policy): 
    REG ADD HKLM\SOFTWARE\Microsoft\WcmSvc\Tethering /v RemoteStartEnabled /t REG_DWORD /d 1 /f

    After executing the command, restart your PC.

If none of the methods helped, use command line (method from the second section) or third-party programs (third section).

5. Common mistakes and their solutions

When distributing Wi-Fi With Windows 10 Users often encounter typical problems. We've compiled the most common errors and how to fix them.

Error 1: "Failed to start hosted network"

Reasons and solutions:

  • 🔌 Wi-Fi adapter does not support Hosted Network → Buy external USB Wi-Fi adapter (For example, TP-Link TL-WN725N, costs ~500 rubles).
  • 🚫 Service Autoconfig disabled → Run it:
    1. Click Win + R, enter services.msc.
    2. Find a service WLAN Automatic Configuration Service.
    3. Right click → Properties → Startup type: Automatic → "Launch".
  • 🔄 Conflict with antivirus → Temporarily disable Kaspersky, Avast or 360 Total Security.

    • Error 2: Devices connect, but the internet doesn't work

    Check the following:

    1. Sharing settings:
      • Open Network and Sharing Center → Change adapter settings.
      • Right click on the main connection (eg. Ethernet) → Properties → Access.
      • Make sure the checkbox is checked "Allow other users..." is checked, and your virtual network is selected in the drop-down menu.
    2. Firewall settings:
      • Open Control Panel → Windows Firewall → Advanced settings.
      • Go to "Windows Firewall Properties" for profile Private Network.
      • Make sure the rule Internet Connection Sharing (ICCS) included.
  • IP addresses:
    • On the connected device (smartphone, tablet), check if it receives IP address.
    • If the address is of the type 169.254.X.X - Means, DHCP doesn't work. Set a static IP manually (for example, 192.168.137.100 with a mask 255.255.255.0).

      • Error 3: Network disappears after reboot

      If you used command line, the network won't be saved after a reboot. To avoid this:

      1. Create .bat- a file with the following contents: 
        @echo off

        netsh wlan start hostednetwork
        

        pause

      2. Put it in startup:
        1. Click Win + R, enter shell:startup.
        2. Place the created file there.
      3. The network will now start automatically when you log in.

      6. How to distribute Wi-Fi from a laptop at 5 GHz?

      By default Windows 10 creates a network at a frequency 2.4 GHz, which is often overloaded and slower. If your Wi-Fi adapter supports 5 GHz, you can force the network to run on this frequency - this will increase the speed and reduce interference.

      To do this:

      1. Open command prompt as administrator.
      2. Enter the command to create a 5 GHz network: 
        netsh wlan set hostednetwork mode=allow ssid="MyWiFi_5G" key="12345678" keyUsage=persistent channel=36

        Where channel=36 - channel in the 5 GHz range (can be used 36, 40, 44, 48, 149, 153, 157, 161, 165).

      3. Start the network: 
        netsh wlan start hostednetwork

    Now your network will operate at the frequency 5 GHzTo check this, connect to it from your smartphone and in the settings Wi-Fi look at the network specifications - there should be a note there 5GHz or 802.11ac.

    ⚠️ Attention: Not all devices support 5 GHz. For example, older smartphones (made before 2015) and some tablets may not recognize this network. In this case, revert to the default 2.4 GHz setting.

    7. Security when sharing Wi-Fi with Windows 10

    Internet distribution via Wi-Fi creates potential vulnerabilities for your computer. Here are the main risks and ways to protect yourself:

    • 🔓 Connecting external devices → Always set a complex password (at least 12 characters, with numbers and special characters).
    • 👁️ Traffic interception → Use VPN on the main device (for example, ProtonVPN or Windscribe).
    • 📤 Personal data leak → Turn off folder sharing in Network and Control Center.
    • 🛡️ Malicious software → Make sure that antivirus software is installed on the connected devices.

    Additional security measures:

    • 🕒 Limit network usage time - Turn off the hotspot when you don't need it.
    • 📱 Use the list of approved devices (in programs like Connectify you can ask MAC addresses approved gadgets).
    • 🔄 Change your password regularly — especially if you distribute Internet in public places.

    If you are distributing internet in a cafe, hotel or other public place, consider creating guest network via third-party programs. This will isolate connected devices from your main network.

    8. Alternative methods of Internet distribution

    If the distribution is through Wi-Fi for some reason it is not possible, you can use other methods:

    • 🔌 Through Ethernet (LAN) - If you have a cable, you can connect another device directly through LAN port (requires crossover cable or adapter).
    • 📶 Bluetooth - slower Wi-Fi, but is suitable for transmitting Internet to a smartphone or tablet (included in Settings → Devices → Bluetooth).
    • 📡 USB cable - some smartphones (for example, Samsung or Xiaomi) support modes USB-ethernet or RNDIS.
    • 📶 Modem mode on a smartphone - If you only have internet access on your phone, you can share it with your PC via USB, Wi-Fi or Bluetooth.

      • For distribution through Ethernet:

      1. Connect the second computer to your PC with a cable.
      2. Open Network and Sharing Center → Change adapter settings.
      3. Right click on the main connection (eg. Ethernet) → Properties → Access.
      4. Allow sharing and select Ethernet 2 (or Local Area Network Connection) in the list.

      The speed with this connection will be higher than Wi-Fi, but physical access to the device will be required.

      FAQ: Answers to Frequently Asked Questions

      Is it possible to share Wi-Fi if I only have a 3G/4G modem?

      Yes, but there are some nuances:

      • If the modem is connected via USB, it needs to be done first permissive for sharing (in Network and Control Center select modem connection in hotspot settings).
      • Some operators (eg. Megaphone or Beeline) block internet sharing from USB modems. In this case, only a third-party program like Connectify.
      • The speed will be lower than when distributing from a cable connection, since the modem itself limits the bandwidth.
      Why is the internet speed when sharing from a laptop lower than on the main device?

      This is normal, and here's why:

      • Wi-Fi adapter The laptop simultaneously receives and transmits a signal, which creates a load.
      • Processor limitations — traffic encryption (especially when WPA2) requires resources.
      • Interference - if there are many other networks nearby on the same channel.

      To improve speed:

      • Switch to 5 GHz (if the adapter supports it).
      • Use cable connection instead of Wi-Fi for receiving the Internet.
      • Turn it off background download of updates on the main PC.
      Is it possible to share Wi-Fi from Windows 10 to a Smart TV or set-top box (Xbox, PlayStation)?

      Yes, but there are limitations:

      • Smart TV (For example, Samsung, LG, Sony) will connect without problems if the network is stable.
      • Xbox One/Series X And PlayStation 4/5 require stable connection — If the ping is high, lags in online games are possible.
      • For consoles it is better to use cable connection or buy a separate router.

      If your TV or set-top box does not connect:

      • Check that the network is working in mode 802.11n (and not 802.11g).
      • Turn it off IPv6 in the connection properties (sometimes this helps).
      • Update your TV/set-top box firmware.
      How to disable Wi-Fi sharing when it is not needed?

      The method depends on the method you used:

      • Mobile hotspot: go to Settings → Network & Internet → Mobile Hotspot and move the slider to the position Off.
      • Command line: enter netsh wlan stop hostednetwork.
      • Third-party programs: close the program or press "Stop Hotspot" in its interface.

      To prevent the network from starting automatically:

      • Delete .bat- file from startup (if created).
      • In programs like Connectify uncheck the box "Run at Windows startup".
      Is it possible to share Wi-Fi from Windows 10 to another computer?

      Yes, but there are some nuances:

      • If the second computer supports Wi-Fi, connect to the created network as to a regular router.
      • If Wi-Fi missing, use Ethernet cable (a crossover cable or adapter is required) or Bluetooth (slower).
      • For stable operation on the second PC, manually enter IP address (For example, 192.168.137.10), If DHCP it doesn't work
