How to share Wi-Fi from your computer using an adapter: complete instructions

Are you in a situation where you urgently need to share internet with several devices but don't have a router handy? Or do you want to save money on a router by using your PC as an access point? With modern Wi-Fi adapters, this is possible—and it doesn't require any advanced technical skills. Simply configure the hardware and operating system correctly.

In this article, we'll cover all the methods for distributing Wi-Fi from a computer using an external or built-in adapter: from standard Windows tools to specialized software. You'll learn which adapter is best for stable distribution and how to avoid common mistakes (for example, lack of internet access for connected devices) and how the modes differ Ad-Hoc And SoftAPIf you're facing the problem "Unable to set up mobile hotspot," there's a solution here.

The material is relevant for Windows 10/11, but the basic principles apply to other operating systems as well. All instructions have been tested on adapters. TP-Link TL-WN725N, ASUS USB-AC56 and built-in modules Intel Wireless-AC 9560If you have a different model, check if it supports the mode. AP (Access Point) in the characteristics.

Which adapters are suitable for distributing Wi-Fi?

Not every Wi-Fi module can operate in access point mode. Here are the key adapter requirements:

• 🔹 Support for SoftAP mode (or AP Mode) is the main requirement. You can check this in the device's specifications or using the command netsh wlan show drivers (see section below).
• 🔹 Driver with Hosted Network support (for Windows). Outdated drivers may not provide this feature even if the hardware supports it.
• 🔹 Transmitter power no less 15 dBm (0.03 W) for a stable signal within the apartment. Adapters with antennas (TP-Link Archer T4U, ASUS USB-AC68) cover up to 20 meters.
• 🔹 Compatibility with standards 802.11n/ac/axTo distribute to modern smartphones and laptops, you need at least 802.11n (up to 300 Mbps).

Among the tested models:

Important: Chip adapters Realtek RTL8188 (For example, TL-WN721N) are often not supported AP Mode It works on Windows, but can also work on Linux. Before purchasing, check this specification with the seller or on the manufacturer's website.

⚠️ Attention: If you are using an adapter with Realtek RTL88x2bu (For example, TP-Link Archer T2U Plus), to distribute Wi-Fi you will need to install the driver from GitHub - the standard Windows driver does not support SoftAP.

Checking for SoftAP mode support in Windows

Before setting up sharing, make sure your adapter is capable of functioning as an access point. To do this:

1. Open Command line as administrator (click Win + X → Terminal (Administrator)).
2. Enter the command:

   netsh wlan show drivers

3. Find the line Hosted network support (Hosted Network Support). If it is indicated there Yes — the adapter fits.

Example of a successful withdrawal:

Name: Wi-Fi
Type: Native Wi-Fi Driver

Hosted Network Support: Yes

If there is no support, update the driver via device Manager or download it from the manufacturer's website. For adapters Realtek And Mediatek Sometimes installing the driver manually helps Install from the specified location → Do not show compatible devices.

Method 1: Sharing Wi-Fi via the command line (without third-party software)

This is a universal method that works on all versions of Windows 10/11. It doesn't require installing any additional software, but it does require entering a few commands.

Step 1: Create a virtual network

Open Command Prompt as administrator and run:

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

Where:

• MyWiFi — the name of your network (may contain spaces and Cyrillic characters).
• 12345678 — password (minimum 8 characters, case sensitive).

Step 2. Starting the distribution

Enter the command:

netsh wlan start hostednetwork

Step 3: Enabling Internet Access

Now you need to "allow" the virtual network to use your primary connection (Ethernet or 4G modem):

1. Open Control Panel → Network and Internet → Network and Sharing Center.
2. Click on your primary connection (eg. Ethernet).
3. Select Properties → Access.
4. Check the box Allow other network users to share your Internet connection.
5. In the drop-down list, select the network you created (usually called Local Area Connection* X).

The adapter supports Hosted Network|The network was created by the command netsh wlan set hostednetwork|Distribution started by command start hostednetwork|Sharing is enabled in the properties of the main connection|Devices see the network in the Wi-Fi list-->

Step 4. Network Management

To stop seeding, use:

netsh wlan stop hostednetwork

To change your username or password, run the command again from Step 1 with new parameters.

⚠️ Attention: After restarting your PC, Wi-Fi sharing is automatically disabled. To avoid this, create .bat-file with command netsh wlan start hostednetwork and add it to startup (folder C:\Users\Your_name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup).

Method 2: Mobile Hotspot in Windows 10/11

Modern versions of Windows have a built-in feature Mobile Hotspot, which simplifies internet sharing. However, it doesn't work on all adapters—if you received an error with the previous method, this method may also fail.

Instructions:

1. Open Settings → Network & Internet → Mobile Hotspot.
2. In the drop-down menu Sharing select your primary connection (eg Ethernet or PPPoE).
3. Click Changeto set the network name (SSID) and password (minimum 8 characters).
4. Turn on the switch Allow other devices to use my internet connection.

If an error appears after switching on Failed to set up mobile hotspot, the reasons may be the following:

• 🔴 The adapter does not support SoftAP (check through netsh wlan show drivers).
• 🔴 The driver is outdated or damaged (reinstall it).
• 🔴 Conflict with antivirus (temporarily disable Kaspersky, Avast or built-in Windows Defender).
• 🔴 Distribution is already running via the command line (stop it with the command netsh wlan stop hostednetwork).

Critical detail: The mobile hotspot in Windows 11 defaults to the 5 GHz band if the adapter supports it. Older devices (e.g., iPhone 6 or Samsung Galaxy S5) may not see this network. To force 2.4 GHz, use the command line (Method 1) with an explicit standard:

netsh wlan set hostednetwork mode=allow ssid="MyWiFi" key="12345678" keyUsage=persistent channel=6

(Where channel=6 — channel in the 2.4 GHz range).

Method 3: Wi-Fi sharing programs (alternatives to standard tools)

If Windows' built-in tools don't work, third-party utilities can help. They offer additional features, such as speed limiting, device blacklisting, and automatic startup at PC startup.
