Wi-Fi Local Area Network in Windows 11: A Complete Guide from A to Z

Creating a local network via Wi-Fi V Windows 11 allows you to connect multiple devices for file sharing, printer sharing, or multiplayer gaming. This procedure is especially relevant for home users who need to quickly connect laptops, smartphones, or even Smart TV without laying cables. However, many people encounter difficulties: the network is not detected, the connection constantly drops, or the data transfer speed leaves much to be desired.

In this article we will look at all possible ways to organize a local network through Wi-Fi V Windows 11 — from standard system tools to alternative solutions using third-party software. You'll learn how to properly configure network settings, avoid common errors, and optimize your connection for maximum performance. And if something goes wrong, there's a section at the end of the article with diagnostics and solutions for the most common issues.

1. Preparing to create a local network: what you need to check in advance

Before you begin setting up, make sure your hardware and software meet the minimum requirements. First, check if your Wi-Fi adapter mode Ad-Hoc or SoftAP (this can be done through device Manager). Secondly, update your network card drivers—outdated versions often cause crashes.

Also pay attention to the version Windows 11. In the latest builds (starting with 22H2) The network creation interface has changed slightly, so the instructions for older versions may not work. To find out your version, click Win + R, enter winver and press Enter.

  • 🔧 Hardware requirements: Wi-Fi adapter with support 802.11n or newer (preferably 802.11ac for stability).
  • 🖥️ Software requirements: Windows 11 (any edition except Windows 11 LTSC, where some network functions are missing).
  • 📡 Additionally: If you plan to connect devices to Android or iOS, make sure they support connection to Wi-Fi Direct.
⚠️ Attention: If you are using a corporate or educational network (for example, in an office or university), the administrator may block the creation of local networks through Group PolicyIn this case, please contact your IT service.

2. Method 1: Creating a Computer-to-Computer (Ad-Hoc) network via the command line

The most reliable method is to use command line (CMD). This method works even where there is a graphical interface Windows 11 refuses to create a network. Open CMD as administrator (click Win + X and select Terminal (Administrator)) and run the following commands:

netsh wlan set hostednetwork mode=allow ssid="NetworkName" key="Password123" keyUsage=persistent

netsh wlan start hostednetwork

Replace Name of the Grid to the desired network name (without spaces and Cyrillic), and Password123 — for a password no less than 8 charactersAfter running the second command, the network should appear in the list of available connections on other devices.

To stop seeding, use the command:

netsh wlan stop hostednetwork
  • 🔄 Network autostart: To make the network start automatically when you turn on your PC, create .bat-file with command netsh wlan start hostednetwork and add it to startup.
  • 📶 Wi-Fi channel: Automatic channel selection is used by default. If the network is unstable, set the channel manually via netsh wlan set hostednetwork channel=6 (range 1–14).
  • 🔒 Safety: Use only WPA2-PSK (installed by default). WEP and open networks are vulnerable to hacking.

The Wi-Fi adapter is enabled in Device Manager.

Adapter drivers have been updated to the latest version.

The command prompt is run as administrator.

The network name (SSID) contains only Latin characters

The password consists of 8+ characters (numbers + letters)

3. Method 2: Using the Mobile Hotspot feature in Windows 11

IN Windows 11 there is a built-in tool Mobile Hotspot, which simplifies the creation of a local network. To activate it:

  1. Open Parameters (Win + I) → Network and InternetMobile hotspot.
  2. In the field Sharing an Internet connection select a source (eg Ethernet or Wi-Fi).
  3. Click Change next to Network name And Network passwordto set your parameters.
  4. Move the slider Mobile hotspot in position On.

This method is more convenient than Ad-Hoc, as it does not require a command line and automatically manages IP addresses through DHCPHowever, it has limitations:

Parameter Ad-Hoc (command line) Mobile hotspot
Max. number of connections Up to 100 (limited by adapter) Up to 8
IPv6 support Yes No
Automatic start Requires a script Yes
Compatibility with Android/iOS Yes (with correct settings) Yes
⚠️ Attention: If other devices cannot connect after turning on the hotspot, check if the connection is blocked Windows Firewall or antivirus (for example, Kaspersky or Avast). Temporarily disable them for the test.

Via command line (Ad-Hoc)

Via Mobile Hotspot

Third-party programs (Connectify, MyPublicWiFi)

4. Method 3: Third-party programs for creating a Wi-Fi network

If built-in tools Windows 11 If you're not satisfied, you can use specialized software. The most popular programs are:

  • 🌐 Connectify Hotspot: A paid solution with advanced features (traffic filtering, connection monitoring). Supports up to 32 devices simultaneously.
  • 🔗 MyPublicWiFi: A free utility with a minimalist interface. It allows you to block unwanted websites on connected devices.
  • 🛠️ Virtual Router Plus: A simple, open-source program. It requires no installation, but may conflict with some adapters.

Example of setting in MyPublicWiFi:

  1. Download the program from official website (avoid third party sources!).
  2. Install and run as administrator.
  3. In the field Network Name (SSID) enter the network name in Network Key - password.
  4. In the section Internet Sharing select the internet source (for example, Ethernet).
  5. Click Set up and Start Hotspot.

Important: Some antivirus programs (for example, ESET NOD32) may block third-party hotspots, viewing them as a potential threat. Add the program to the exceptions list or temporarily disable protection.

5. Setting up file and printer sharing

Creating a network is only half the battle. For devices to exchange data, you need to set it up. public accessTo do this:

  1. Open Control PanelNetwork and InternetNetwork and Sharing Center.
  2. Select Change advanced sharing options.
  3. Turn on Network discovery And File and Printer Sharing for profile Private.
  4. Turn it off Password-protected sharing (if all devices are trusted).

Now you can share folders:

  1. Right-click on the folder → Properties → tab Access.
  2. Click Share and select users (eg All).
  3. Set the access level (Reading or Reading and writing).

To connect to a shared folder from another device, enter the following in File Explorer:

\\[computer_IP_address]\folder_name

For example: \\192.168.137.1\Documents.

How do I find out my computer's IP address?

Open command prompt and type ipconfig. Look for the line IPv4 address in the section Wireless LAN adapter (for Wi-Fi) or Ethernet adapter (for cable).

6. Diagnosing and solving common problems

If your local network is not working, please check the following:

  • 🔌 No connection: Make sure the main PC is turned on. Internet access sharing (in connection properties → tab Access).
  • 🔄 Constant breaks: Change the Wi-Fi channel in the adapter settings (via device ManagerAdapter propertiesAdditionally).
  • 🚫 Unable to connect: Check if it is blocking the connection firewall or antivirus. Also, make sure the password is entered correctly (case is important!).
  • 🐢 Low speed: Turn off power saving for your Wi-Fi adapter (in Device ManagerPower management → uncheck Allow shutdown...).

If the issue persists, reset your network settings:

  1. Open ParametersNetwork and InternetAdditional network settingsNetwork reset.
  2. Confirm the action and restart your PC.
⚠️ Attention: After resetting the network, all saved Wi-Fi passwords will be deleted. Please save them in a text file beforehand.

7. Optimize your local network for gaming and streaming

If you're creating a network for multiplayer gaming or video streaming, the default settings may not provide sufficient speed. Here's what you can do:

  • 🎮 For games: In the adapter settings (device Manager) turn it off Green Ethernet And Energy Efficient Ethernet. Also set traffic priority for gaming applications in Qos (if the router supports it).
  • 📺 For streaming video: Use 5 GHz-band (if the adapter supports it). It's less congested and provides greater throughput.
  • For all cases: Disable background downloads (e.g. updates) Windows or Steam) on the main PC.

To test the speed between devices on a local network, use the utility iPerf3:

iperf3 -s # on the server (main PC)

iperf3 -c [server_ip_address] # on the client

If the speed is lower 50 Mbps, check:

  • Distance between devices (optimally up to 10 meters without obstacles).
  • Presence of interference from other networks (use a Wi-Fi analyzer, for example, NetSpot).
  • The adapter operating mode (ideally - 802.11ac or 802.11ax).

8. Local Wi-Fi Network Security: How to Protect Data

A local Wi-Fi network is vulnerable to attack, especially if it uses weak passwords or outdated protocols. Follow these recommendations:

  • 🔐 Password: Use a combination of 12+ characters (numbers, upper and lower case letters, special characters). Example: W1n$P0t!2026@Lan.
  • 🛡️ Encryption: Always choose WPA2-PSK (AES). WPA3 Not supported by all devices yet.
  • 👤 Connection control: Check the list of connected devices regularly through arp -a in the command line.
  • 🔄 Updates: Install security patches for Windows 11 and adapter drivers.

If other devices are connected to the network, immediately change the password and scan your PC for viruses (for example, using Malwarebytes or Dr.Web CureIt!).

⚠️ Attention: Never use a local Wi-Fi network to transmit confidential data (passwords, banking details) without additional encryption (for example, via VPN or SSH tunnel).

FAQ: Answers to frequently asked questions

Is it possible to create a local network between a PC and a Mac?

Yes, but there are nuances. Mac you need to manually configure the IP address in the local network range (for example, 192.168.137.100 with a mask 255.255.255.0) and disable the firewall. Also make sure that Windows 11 protocol enabled SMB (V Turn Windows features on or off).

Why is the speed on a local network lower than via cable?

Wi-Fi is always slower than Ethernet due to interference, limitations of the standard (max speed 802.11ac — ~867 Mbps versus 1–10 Gbps via cable) and encryption overhead. To improve the situation:

  • Use 5 GHz-range.
  • Reduce the distance between devices.
  • Disable power saving for your Wi-Fi adapter.
