In today's digital world, the need to quickly transfer large amounts of data between devices is common. Using external hard drives or cloud storage isn't always convenient, especially when the internet connection is congested or the write speed to a USB drive is slow. In these situations, creating a direct connection between a laptop and desktop computer using only the built-in Wi-Fi module becomes crucial.
Setting up a local network not only allows you to instantly share documents, photos, and videos, but also provides access to shared resources such as printers or media libraries. Local area network A wireless LAN (LAN) eliminates the need to run cables throughout the apartment. This solution is ideal for those who work with multiple machines simultaneously and want a unified information space.
There are several proven methods for implementing this task, each with its own features and use cases. You can set up a full-fledged home network, use Windows sharing features, or use specialized synchronization software. The choice of a specific method depends on the operating system version, router model, and your personal preferences for security and convenience.
Equipment preparation and compatibility testing
Before beginning setup, ensure your equipment is ready for network operation. A key requirement is having working Wi-Fi adapters on both devices. While laptops come with these adapters by default, desktop computers may require an external USB dongle or an internal PCIe card. Ensure that the network hardware drivers are installed correctly and that the devices are working without conflicts.
Both computers must be connected to the same wireless network. This is a fundamental rule, as it will be impossible to detect devices in the list of available resources without it. If you're using a guest Wi-Fi network, make sure AP Isolation isn't disabled in your router settings, as this feature blocks local data exchange for security reasons.
It's also worth paying attention to the network type assigned by your operating system when you first connected. To successfully share files, the network profile must be set to "Private" or "Home," but not "Public." By default, the system hides your computer from other devices in a public profile to protect your data in cafes or airports.
⚠️ Attention: If you're using corporate Wi-Fi with web portal or certificate authentication, creating a local network may be blocked by your organization's security policies. In this case, please contact your system administrator.
- 📡 Make sure both devices can see your Wi-Fi network and have a strong signal.
- 🔌 Check that your network adapter drivers are updated to the latest version.
- 🔒 Make sure your antivirus isn't blocking incoming connections on your local network.
Setting up sharing in Windows
After checking the physical connection, you need to properly configure the operating system settings. In Windows 10 and 11, these settings are located under "Network & Internet Settings." You'll need to find "Advanced sharing settings," where you can enable network discovery. Without this feature, your computer simply won't "see" other devices in File Explorer.
The next step is to enable file and printer sharing. Network protocol SMB, which Windows uses for file transfers, must be enabled on both ends of the connection. It's also recommended to disable password protection if you completely trust users on your home network, although this reduces security. If password protection is enabled, you'll have to enter the remote computer's username and password each time you connect.
For those who prefer the classic interface, settings are available through the Control Panel. Go to "Network and Sharing Center" and select "Change advanced sharing settings." Here you can fine-tune which folders are readable and writable, and whether to encrypt transferred data.
Sometimes a reboot of the network adapter or the computer itself is required for discovery services to function correctly. If, after enabling all options, the computers still can't see each other, try temporarily disabling the firewall to test.
- 🖥️ Enable network discovery in your private network profile.
- 📂 Turn on file and printer sharing.
- 🔑 Decide whether you need password protection to access resources.
Creating a folder for data sharing
Once the basic network settings are complete, you need to select or create the resource you plan to share. You can grant access to the entire disk, which is convenient for administration, or you can select a specific folder, such as "File Sharing." The latter option is more secure, as it restricts access to only a specific set of documents.
To configure access permissions, right-click the selected folder and go to Properties. Select the "Access" tab. Click "Advanced" and check "Share this folder." In the permissions window, you can fine-tune the actions users can perform: read-only, modify, or full control over files.
net share ShareName=C:\Exchange /grant:Everyone,FullYou can also use the built-in "Shared Folders" feature, which automatically creates an access point for all users on the system. This simplifies the process, but provides less control over individual files. For most home users, simply sharing a single folder with the correct access rights is sufficient.
☑️ Setting up access rights
Don't forget to check the path to the network folder. It usually looks like this: \\ComputerName\FolderName or \\IP Address\FolderNameYou'll need this address on the second computer to quickly access resources without a long search through the network environment.
⚠️ Attention: Granting "Full Control" permissions allows any network user to delete or modify files. Use this option only for trusted devices.
Connecting to a network resource
Now that the resource is prepared, let's move on to the actual connection. Open File Explorer on the second computer (laptop or PC) and go to the "Network" section. If everything is done correctly, you should see the name of the first computer in the list of available devices. Double-clicking it will open a list of shared folders.
If the computer does not appear in the list, you can use direct address entry. Press the key combination Win + R, in the window that appears, enter the IP address or name of the host computer. For example, \\192.168.1.5The system will prompt you for credentials if password protection is enabled on the host. Enter the login and password of the user account logged in to the primary computer.
For ease of use, we recommend mapping the network folder as a network drive. In File Explorer, click "This PC," then select "Map network drive" from the top menu. Select the drive letter (e.g., Z:) and enter the path to the folder. The remote resource will now appear in "My Computer" as a regular hard drive, making it much easier to work with files.
What should I do if Windows asks for a password but doesn't accept it?
Often, the problem is that the remote computer is using a Microsoft account rather than a local one. In this case, try entering the email address associated with your Microsoft account as the username. Also, make sure the same passwords are set for the same usernames on both computers.
File copy speed over Wi-Fi will depend on the wireless standard (802.11n, ac, ax) and the distance from the router. When transferring large amounts of data, try to stay close to the access point to ensure a stable signal and maximum throughput.

Alternative methods of file transfer
If the built-in Windows tools seem too complicated or unstable, there are third-party solutions that simplify the data exchange process. One of the most popular methods is using synchronization programs like Resilio Sync or Syncthing. They create a P2P connection between devices, automatically updating files in the background without the need for complex access rights settings.
Another effective method is to create an FTP server on one of your computers. There are lightweight servers, such as FileZilla Server, that can turn your PC into a file storage device. Connection is made through any browser or FTP client, making this method cross-platform and independent of Windows versions.
To quickly transfer small files, you can use Nearby Sharing, a feature built into Windows 10 and 11. It uses Bluetooth and Wi-Fi Direct to detect nearby devices. Simply select the file, click "Share," and choose the target device from the list. The file will arrive as a notification, which you'll need to accept.
| Method | Speed | Difficulty of setup | Security |
|---|---|---|---|
| Shared folder (SMB) | High | Average | Depends on the password |
| FTP server | High | High | Low (no encryption) |
| Third-party software (Sync) | Average | Low | High (encryption) |
| Nearby Sharing | Low | Low | Average |
⚠️ Attention: Program interfaces and menu item names may vary depending on the operating system version and Windows updates. If you can't find the option, try searching in the system settings.
The method you choose depends on your goals. For ongoing document management, a network drive is best. For one-time transfers of movies or archives, Nearby Sharing or a temporary shared folder is more convenient. The most important thing is to ensure a stable Wi-Fi connection, as this is the bottleneck of the entire system.
Troubleshooting and diagnostics
Despite the apparent simplicity, users often encounter connection errors. One of the most common issues is the access error "You do not have permission to access this object." This can be resolved by checking the "Security" tab in the folder properties and adding the "Everyone" user or a specific user with read and write permissions.
Another common problem is that computers simply don't see each other on the network. In this case, check the "Function Discovery Resource Publication" service. It should be running and running automatically. Without this service, modern versions of Windows hide the computer from the network environment.
It's also worth paying attention to your antivirus software. Third-party antivirus programs (Kaspersky, ESET, Avast) often have their own built-in firewalls that can block your local network, even if the standard Windows firewall is configured correctly. Try temporarily disabling protection or adding your network to the trusted list in your antivirus settings.
netsh advfirewall firewall set rule group="Network Discovery" new enable=YesIf all else fails, try resetting your network settings. In Windows 10 and 11, you can do this via Settings → Network & Internet → Advanced network settings → Network reset. This will reset all network adapters and protocol settings to their factory defaults, which often resolves software conflicts.
Why is the Wi-Fi transfer speed much lower than stated?
Wi-Fi speed is divided equally among all connected devices and depends on distance, interference, and the router standard. Furthermore, the SMB protocol has overhead. Actual speed is often 50-70% of the standard's theoretical maximum speed.
Is it possible to connect computers directly without a router?
Yes, this is possible by creating a wireless ad-hoc network. However, in Windows 10/11, this feature is hidden and requires creating a special XML profile or using the command line, which is more complicated than connecting through a router.
How do I find out the IP address of a computer to connect to?
Open command prompt (cmd) and enter the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter. This is the address you need to enter on the second device.
