Situations where you urgently need to transfer gigabytes of photos, large video archives, or work projects to another computer arise regularly. Using external USB drives often seems like the most obvious solution, but it's not always effective: flash drives get lost, have limited write speeds, and there's simply no time to fumble around for a cable. Fortunately, modern technology allows for high-speed data transfer directly, using only the capacity of your local wireless network.
Transferring data over the air today is not just copying Word documents, but a full-fledged alternative to wired connections, especially when it comes to Windows 10 and 11Next-generation Wi-Fi standards provide sufficient bandwidth for 4K video and system backups. In this article, we'll explore proven methods that don't require the installation of questionable software and allow you to quickly establish a connection between devices.
The main advantage of wireless transmission is that it doesn't require a physical port and allows for simultaneous connection of multiple devices. However, for stable operation, it's crucial that both laptops are on the same network and have the correct access settings. We'll cover both built-in operating system tools and specialized utilities that simplify this process to just a few clicks.
Infrastructure preparation and network testing
Before setting up shared access or launching specialized software, you need to ensure that the basic network settings are working correctly. A stable connection between nodes is the foundation for any data transfer. If laptops are connected to different router frequencies (for example, one to 2.4 GHz and the other to 5 GHz), they will still be able to see each other, but the speed may be limited by the slower channel.
The first step is to check the network type in your operating system. Windows assigns new connections the "Public Network" profile by default, which blocks your device from being visible to other computers for security reasons. You need to change this status to "Private Network" to allow discovery. You can do this through the Control Panel or network settings, where you'll be asked to trust the current connection.
⚠️ Attention: Switching your network profile to "Private" makes your laptop visible to all devices within Wi-Fi range. Ensure you're on a secure home network or trusted by your office network to avoid unauthorized access to your resources.
It's also worth checking that network discovery is enabled. Without this setting, the system will ignore requests from other computers, even if the passwords and usernames are correct. Open Control Panel, go to Network and Sharing Center, and select "Change advanced sharing settings." Here, enable the "Turn on network discovery" and "Turn on file and printer sharing" options for the current profile.
Shared Folder (SMB) Method for Persistent Operation
The most reliable and native way to organize data exchange in a Windows environment is to create a shared folder using the SMB protocol. This method is ideal for situations where large amounts of information need to be regularly transferred between desktop workstations. It doesn't require an internet connection and operates exclusively within your local network, ensuring maximum speed limited only by the router's power.
To begin, create the folder you want to share, or use an existing one. Right-click it and select "Properties," then go to the "Sharing" tab. Click "Shared" and in the window that opens, add the user "Everyone" (or a specific user), setting their permissions to "Read and Write." This will allow the second laptop to not only retrieve files but also upload them to this directory.
After setting up access rights, you need to find out the IP address of the server computer to connect to it from another device. Open the command prompt by entering cmd in the Start menu and use the command ipconfigFind the "IPv4 Address" line in the section for your Wi-Fi adapter. On the second laptop, open File Explorer and enter [IPv4 Address] in the address bar. \\192.168.1.XX (where XX is the address of the first laptop) and press Enter.
☑️ Setting up a shared folder
The first time you connect, the system may ask for credentials. Enter the username and password for the user account on the first laptop. If there is no password, you may need to enable passwordless login in the advanced sharing settings, although this reduces the security level. After successful login, the folder will open as a regular directory, and you can copy files at your usual speed.
Nearby Sharing feature in Windows 10/11
For one-time document or photo transfers, it's much more convenient to use the built-in Nearby Share feature, which works similarly to AirDrop in the Apple ecosystem. This technology uses a combination of Bluetooth for device discovery and Wi-Fi Direct for fast data transfer, eliminating the need for complex IP address configuration and shared folders.
To activate the function, open the Settings (keys Win + I), go to the "System" section and find "Nearby Sharing." Make sure the toggle is enabled, and select either "Everyone Around" or "My Devices." The first option will allow all nearby devices to see your laptop, while the second option will only allow devices signed in with your Microsoft account to see your laptop.
⚠️ Attention: The Nearby Sharing feature requires Bluetooth to be enabled on both devices. If the Bluetooth drivers are not installed correctly or the module is disabled, device discovery will not work, even if Wi-Fi is active.
The transfer process is extremely simple: select the file you want to send, right-click, and select "Share." The second laptop should appear in the list of available devices. After clicking it, a notification will pop up on the receiving end asking if you want to save the file. Once confirmed, the upload will begin.
Why is detection not working?
If the laptops can't see each other, check that Airplane mode isn't enabled. Also, make sure Windows Firewall isn't blocking the Link to Windows app or Bluetooth services. Restarting the Workstation Features service via services.msc can sometimes help.
Nearby Sharing typically offers faster transfer speeds than Bluetooth, but may be slower than direct SMB transfers over a gigabit network due to the discovery protocols involved. However, for files up to several gigabytes in size, it's the fastest, most immediate option, eliminating the need to enter passwords or configure network masks.
Using an FTP Server for Advanced Users
If you require more flexible control over transferred data or want to access laptop files from a mobile device or another PC without tying them to Windows accounts, deploying an FTP server is the best solution. FTP (File Transfer Protocol) is the de facto standard for file sharing and runs over TCP/IP.
Windows doesn't have a built-in graphical interface for quickly creating an FTP server in one click, so the easiest way is to use lightweight third-party software, such as FileZilla Server Or even the built-in IIS component, although the latter is overkill for home use. After installing the server, you'll need to specify the root directory to be accessed and set up a user with a password.
The advantage of this method is its cross-platform compatibility and the ability to interrupt downloads. If the transfer of a large file is interrupted, the FTP client can only finish downloading the missing portion, rather than starting the process over again. To connect on the client machine, use any browser or file manager (such as Total Commander), entering a URL like ftp://192.168.1.XX.
| Method | Speed | Difficulty of setup | Security |
|---|---|---|---|
| Shared folder (SMB) | High | Average | High (depending on password) |
| Exchange nearby | Medium/High | Low | Average (requires confirmation) |
| FTP Server | Very high | High | Depends on configuration |
| Synchronization (Resilio) | Depends on the network | Low | High (encryption) |
When setting up FTP, it's important to keep ports in mind. Port 21 is used by default, but it's often blocked on corporate networks. In this case, you can reassign a non-standard port (for example, 2121), but then you'll need to explicitly specify it in the address when connecting: ftp://192.168.1.XX:2121.
Synchronization via P2P utilities (Resilio Sync, Syncthing)
For those who plan to keep folders on two laptops up-to-date, P2P (peer-to-peer) synchronization programs are the ideal solution. Unlike cloud storage, data doesn't go through third-party servers, but is transferred directly between devices over the internet or local network.
One of the best utilities in this segment is SyncthingIt's free, open-source, and requires no registration. After installing on both laptops, you receive a unique device ID. By adding the second laptop's ID to your friends list and selecting a sync folder, you start the process. The program will automatically find the device on your local network and begin instant syncing.
The main advantage of such solutions is the absence of file size limits and the ability to work in the background. You simply work with files in a regular folder, and the program seamlessly updates their copies. This is especially important for photographers and video editors who need to transfer source files between the studio and home.
Setting up a Wi-Fi Direct connection
Wi-Fi Direct technology allows devices to connect directly to each other without the need for a router or access point. This creates a virtual local area network (VLAN) between two laptops, ensuring high data transfer speeds. However, in Windows, the implementation of this protocol is often hidden and relies on wireless adapter drivers.
Using Wi-Fi Direct in its purest form often requires specialized software from the adapter manufacturer (such as Intel PROSet/Wireless Software) or third-party utilities. In the standard Windows interface, this feature is often hidden by services like Nearby Sharing or Miracast. If your laptop supports mobile hotspot creation, you can emulate the role of a router.
Enable "Mobile Hotspot" in the network settings on one laptop and connect the second one to the created network. This creates a direct connection. Speeds in this mode can be even higher than through a regular router, since traffic doesn't go through the router's processor and buffer, but goes directly between the adapters.
⚠️ Attention: When creating a mobile hotspot, the primary laptop may temporarily lose internet connection if the network adapter doesn't support both client and hotspot mode. Check the specifications of your Wi-Fi module.
This method is suitable for field conditions where there's no Wi-Fi infrastructure but you need to transfer a large file. The only drawback is the need to re-pair the devices or enter the password for the created network each time.
Comparison of methods and selection of the optimal solution
The choice of transfer method depends on your specific tasks and frequency of use. If you need to transfer a single file to a colleague in the next office, nothing is more convenient than "Nearby Sharing." For ongoing access to archives on a home server, it's best to set up an SMB folder once. For synchronizing work documents between the office and home, P2P utilities are indispensable.
Don't forget about the bandwidth of your equipment. If your router supports the standard Wi-Fi 6 (802.11ax), network transfer speeds can reach hundreds of megabits per second, comparable to fast USB flash drives. However, older 802.11n routers can become a bottleneck, limiting speeds to 2-4 MB/s.
Security is also important to consider. When working in public spaces (cafes, coworking spaces), using shared folders without a password or open FTP can lead to data leakage. In such situations, it is preferable to use secure connections or temporary P2P channels with key generation.
Why is the speed when transmitting via Wi-Fi significantly lower than stated?
Actual Wi-Fi speed is always lower than theoretical due to protocol overhead, interference, and distance from the router. Furthermore, speed drops if devices operate in the 2.4 GHz band, which is heavily congested with neighboring networks and household appliances.
Is it possible to transfer files if the laptops are on different networks (via the Internet)?
Yes, but standard methods like SMB or Nearby Sharing won't work. To transfer data over the internet, you'll need to set up port forwarding on your router (complicated and dangerous) or use P2P programs like Resilio Sync, which can penetrate NAT, or cloud storage.
How to speed up the transfer of large files over the network?
Make sure both devices are connected to the 5 GHz band. Disable antivirus scanning of network files during the transfer. Use a wired connection (Ethernet) for at least one of the nodes, if possible, or ensure you have a direct line of sight to the router.
