Organizing stable data exchange between devices in an apartment or house is no longer the preserve of system administrators at large corporations. local area network This is essential for streaming video to a TV, quickly transferring large files between computers, or organizing network storage. In Windows 10, this process is significantly simplified, although it still requires careful attention to security settings.
Before undertaking any complex manipulations, it's important to ensure all devices are in the same information space. This means the laptop, desktop PC, and media player must be connected to the same router. Modern routers automatically isolate clients from each other on guest networks, so use your main Wi-Fi network to create a LAN.Only if this condition is met will the operating system be able to correctly detect neighboring nodes.
In this article, we'll cover not only the basic setup but also the nuances that beginners often overlook, leading to visibility errors. You'll learn how to properly configure profiles, manage access rights, and use modern data transfer protocols while avoiding outdated methods.
Checking basic conditions and preparing equipment
The foundation of any local network is a physical connection. In the case of a wireless connection, the cable acts as a radio channel, the stability of which directly affects data transfer speed. Make sure your router supports the standards. 802.11n or 802.11ac, as older protocols can become a bottleneck when transmitting large amounts of information.
Each device you plan to connect to the network must have properly installed network adapter drivers. Visibility issues are often caused by network card software that incorrectly handles discovery protocol broadcast requests.
- 📡 Check that all devices are connected to the same SSID (network name) of the router.
- 💻 Make sure all PCs are running Windows 10 or later for protocol compatibility.
- 🔌 Reboot your router if it has been running continuously for more than a month.
It's also worth paying attention to the frequency range. If your router is dual-band, it's better to use the 5 GHz network for faster speeds, but keep in mind that it has a shorter range. For devices located farther from the access point, 2.4 GHz may be more stable, albeit slower.
Network profile setup and discovery
The first critical step in Windows 10 is determining your network type. By default, the operating system assigns new connections the "Public Network" profile, which prevents other devices from seeing your computer for security reasons. You must manually change this status to "Private Network."
To do this, go to the menu Start → Settings → Network & Internet → StatusClick on your Wi-Fi connection properties. In the window that opens, select the "Private" profile. This will allow incoming connections and make your PC visible to your network neighbors.
⚠️ Attention: Never change your profile to "Private" if you're connected to public Wi-Fi at a cafe or airport. This will expose your data to potential attacks from hackers on the same network.
After changing the profile, the system will automatically apply the new firewall rules. However, sometimes additional verification is required. Open Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsHere, the "Turn on network discovery" and "Turn on file and printer sharing" options should be enabled.
Enabling file and folder sharing
Once the computers have "seen" each other, permission to share data must be granted. Windows 10 offers a flexible permissions management system that allows access to the entire system or just specific directories.
To start using shared resources, return to the advanced sharing options menu. Find the "All Networks" section and scroll down to "Password-protected sharing." If you trust all devices in your home, you can disable this option, allowing you to connect without entering your account login and password.
If security is your priority, leave protection enabled. This way, when attempting to access the folder from another computer, the system will prompt you for the username and password of the user whose folder is being shared. This creates an additional barrier to unauthorized access.
To share a specific folder, right-click on it, select Properties → Access → Advanced settingsCheck the "Share this folder" box and click the "Permissions" button to specify who can read or change files.
☑️ Setting up sharing
Using the Shared Folders feature
Windows 10 has a dedicated system folder for quick sharing. It's located at C:\Users\GeneralFiles placed in subfolders of this directory (for example, "Shared Documents" or "Shared Pictures") are automatically made available to other network users if the corresponding feature is enabled.
This method is convenient because it doesn't require manually setting permissions for each individual folder. However, it has a limitation: all users on the local computer have access, not just network guests. Therefore, it's important to monitor the contents of this directory.
To enable this feature, find the "Use password-protected sharing" option in the sharing settings (in some interface versions it may have a different name, for example, "Turn on public folder sharing").
| Access method | Security level | Difficulty of setup | Recommended use |
|---|---|---|---|
| Public folder | Short | Minimum | Quick exchange of temporary files |
| Shared folder | Medium/High | Average | Permanent libraries of media and documents |
| OneDrive (Network) | High | High | Synchronization between devices via the cloud |
Why is the folder not visible on the network?
If you've configured access but the folder isn't showing up, try restarting the Function Discovery Resource Publishing service. Also, make sure your antivirus isn't blocking local connections.
Mapping a network drive for ease of use
Constant input of network paths in the format \\IP address\Folder It's extremely inconvenient. Windows allows you to map a remote folder to a local drive letter, making network resource management transparent for both the user and applications.
Open "This PC" and select "Computer" → "Map network drive" from the top menu. Select an available drive letter (e.g., Z:) and enter the path to the resource. If desired, check "Reconnect at logon" to make the drive appear automatically after a reboot.
This feature is especially useful for media players and video editing programs that don't support UNC network paths. To the system, it will appear as a regular hard drive partition.
Connection errors may occur if the IP address of the target computer has changed. To avoid this, it's recommended to reserve a static IP address for the computer where the files are located in your router settings.
Diagnosis and troubleshooting of common errors
Even with proper configuration, situations may arise where devices cannot see each other. Most often, the problem lies in Windows services that have stopped for some reason, or in the network adapter's power saving settings.
Check the service status Function Discovery Resource Publication. Click Win + R, enter services.msc and find this service in the list. Set the startup type to "Automatic" and start it. Without this service, the computer will not advertise itself on the network.
- 🔍 Check if your antivirus software is blocking your local network (Public Network mode in your firewall).
- ⚡ Disable power saving for the Wi-Fi adapter in Device Manager.
- 🔄 Reset network settings with the command
netsh winsock resetin the command line.
⚠️ Attention: The Windows 10 Settings interface is constantly being updated. The location of some menu items may vary depending on the build version (21H2, 22H2, etc.). If you don't find the item you're looking for, try searching in the system settings.
The SMB 1.0 protocol is also worth mentioning. In newer versions of Windows, it is disabled by default due to vulnerabilities. If you are trying to connect a very old network drive or printer, you may need to enable support for this protocol using "Turn Windows features on or off," but this should only be done if absolutely necessary.
Questions and Answers (FAQ)
Is it possible to create a local network if there is no router?
Yes, this is possible using Wi-Fi Direct technology or creating a virtual access point (Hosted Network) on one of the laptops. However, the speed and stability of this connection will be lower than using a full-fledged router.
Why am I asked for a password when connecting, even though I didn't set one?
Windows requires authorization. You need to enter the login and password for the user account on the computer whose folder you're connecting to. If there's no password, you'll need to create one in your account settings.
How to find out the IP address of a computer on a local network?
Open command prompt (cmd) and enter the command ipconfigYou're interested in the "IPv4 address" line. This is the address you need to enter on other devices to connect.
Will the local network work without the Internet?
Yes, a local network functions regardless of internet access. The main requirement is that the devices are connected directly via a router or cable.
