In today's digital world, the need to urgently transfer photos, documents, or large video files between devices arises constantly. Wired solutions, such as USB flash drives or external hard drives, are often at the wrong time, and their speed can be disappointing when transferring gigabytes of data. That's why the question... How to transfer data from one computer to another via WiFi, remains one of the most relevant for local network owners.
Fortunately, built-in operating system tools and specialized software allow file exchange at speeds significantly exceeding Bluetooth capabilities, without the need to search for cables. Local area network A LAN (LAN) can ensure stable data transfer if security and sharing settings are properly configured. In this article, we'll cover all the nuances of wireless transfer, from standard Windows tools to advanced third-party solutions.
Before you begin setup, you need to make sure both devices are connected to the same wireless network. This is a basic requirement, without which transmission protocols They simply won't be able to detect the other party. If the router broadcasts a signal at 5 GHz, the copying speed will be significantly higher than in the crowded 2.4 GHz band.
Equipment preparation and basic network setup
The first step is to check the visibility of your devices. The operating system must treat your connection as a "Private Network" rather than "Public" to allow other PCs to be discovered. In Windows 10 and 11, you can check this by opening Settings → Network & Internet → StatusIf the network status is marked as "Public", the system blocks incoming connections for security purposes.
Next, you need to make sure that network discovery is enabled on both computers. Without this feature, your router The network will simply transmit data packets, but the computers will ignore connection requests. Go to Control Panel, select Network and Sharing Center, and click Change advanced sharing settings.
⚠️ Caution: When enabling public access in apartment buildings without a strong WiFi password, neighbors could theoretically access your folders. Always use a complex password to secure your wireless network.
In the "Private" network section, enable the following options: "Turn on network discovery" and "Turn on file and printer sharing." You should also enable the "Let Windows manage HomeGroup connections" option if you're using older versions of the OS. After saving the changes, the system may require a restart of the network services or the PC itself.
For stable operation, it is recommended to assign static IP addresses to devices or reserve them in the router settings. Dynamic address change (DHCP) may cause the connection to be broken during a long file transfer when one of the computers decides to renew its address lease.
Using the Shared Folder feature in Windows
The most native method, which doesn't require installing any additional software, is folder sharing. You create a directory where you place files and make it accessible over the network. Open File Explorer, select the desired folder, right-click, and go to "Properties." You'll be looking for the "Sharing" tab.
Click the "Advanced Settings" button and check the "Share this folder" box. You can also configure permissions here: allow read-only access or grant full control (read and write). For corporate networks, it's important to restrict permissions to prevent colleagues from accidentally deleting your files. data archives.
Once configured, on the second computer, open File Explorer and in the address bar, enter the IP address of the first computer in the format \\192.168.1.XIf the system prompts you for credentials, enter the username and password used to log in to the first PC. This is the standard authorization procedure for a domain or home network.
- 📁 Create a separate folder for sharing to avoid sharing your entire drive.
- 🔐 Use the same logins and passwords on both PCs for automatic login.
- 📶 Make sure your firewall is not blocking the SMB protocol (port 445).
If you plan to transfer files regularly, it makes sense to map the network folder as a separate drive. In File Explorer, click "This PC," select "Map network drive," and specify the drive letter and path to the resource. Now data exchange will be as easy as copying files to a flash drive, only without physical contact.
☑️ Checking sharing settings
It's worth noting that the speed of copying files via a shared folder directly depends on the quality of the WiFi signal. If the router is in another room behind a thick wall, the speed may drop to 1-2 MB/s, which is critical for large volumes.
Transfer via Nearby Sharing
Windows 10 and 11 have a built-in feature similar to AirDrop in the Apple ecosystem. It's called "Nearby Sharing" and uses a combination of Bluetooth for discovery and WiFi Direct for file transfer. It's ideal for quickly sharing documents or a few photos without complicated setup.
To activate the feature, go to Settings → System → Shared FilesMake sure the "Proximity" toggle is set to "On." Also, choose who can see your computer: "Just my devices" (requires signing in to a single Microsoft account) or "Everyone around me."
To share a file, simply right-click on it and select the Share icon (or press Win + A and select "File Transfer." The system will begin searching for available devices nearby. A notification will appear on the receiving computer, which you must confirm.
⚠️ Please note: The Close Range feature only works over relatively short distances (up to 10 meters) and requires Bluetooth and WiFi adapters to be enabled on both computers.
The main advantage of this method is that there is no need to enter IP addresses or configure access rights. However, for transferring files larger than 1-2 GB, this method may be less stable than a classic shared folder due to its operating characteristics. WiFi Direct protocol.
What should I do if the function doesn't see another computer?
Make sure Bluetooth is enabled on both PCs. Check that the power settings aren't set to disable the Bluetooth adapter to save power. This feature may also not work if the devices are on different subnets or if guest WiFi is enabled.
Specialized software for fast transfer (Syncthing, Resilio)**
When standard Windows tools fail or require too much manual configuration, cross-platform utilities come to the rescue. Programs like Syncthing or Resilio Sync Create a direct connection between devices, bypassing complex Windows settings. They're ideal for syncing large folders in the background.
The principle is simple: you install the program on both computers, add a folder for syncing, and enter a unique key or QR code to pair the devices. After that, any changes to files on one computer are automatically reflected on the other via WiFi.
The main advantage of these solutions is their independence from the operating system. You can transfer data from Windows to macOS, Linux, or even an Android smartphone. Transfer speed is limited only by your router's bandwidth and signal range.
| Program | License type | Complexity | Peculiarities |
|---|---|---|---|
| Syncthing | Open Source | Average | Complete privacy, no cloud |
| Resilio Sync | Freemium | Low | User-friendly interface, quick setup |
| Send Anywhere | Free | Low | Transfer by 6-digit code |
| Dukto | Free | Low | Simplicity, no settings |
Using third-party software is especially useful if you need to regularly sync work projects between your home and work laptops. You won't have to search for files on your network every time—they'll simply appear in the right folder.
Using an FTP Server for Advanced Users
For those who prefer complete control over the process, creating an FTP server on one of the computers is the optimal solution. This method ensures high speed and reliability, and allows the use of specialized clients that can resume interrupted downloads.
In Windows, you can deploy an FTP server through the IIS (Internet Information Services) component or use lightweight programs like FileZilla ServerAfter installation, you will need to specify the root folder, set access rights and (usually 21).
Connection is made through any browser or FTP client (for example, FileZilla Client or Total Commander) by entering the address ftp://server-ip-addressThis method is good because it does not depend on Windows versions and domain network policies.
- 🚀 High speed transfer of large files without freezing.
- 🛡️ Possibility to configure encryption (FTP over SSL/TLS).
- 📝 Logging of all connections and transferred files.
However, setting up FTP requires basic knowledge of network protocols. Incorrectly configured firewalls can block the connection, and using standard FTP without encryption makes data vulnerable to interception on open networks.
Troubleshooting and connection diagnostics
Even with proper configuration, errors may still occur. The most common issue is "Windows cannot access the path specified." This is often due to ports being blocked by antivirus software or network profile mismatches. Ensure the network profile is set to "Private" on both PCs.
If the transfer speed is extremely low (less than 1 MB/s), it's possible that one device is connected via the 2.4 GHz band and the other via the 5 GHz band, and the router is routing traffic between them inefficiently. Also, try temporarily disabling your antivirus firewall to check.
If the computers can't see each other at all, try resetting the network settings. Open the command prompt as administrator and enter the command netsh winsock reset, then restart your computer. This will reset your network drivers to factory settings.
⚠️ Note: Settings interfaces and menu item names may vary depending on your Windows version (Home, Pro, Enterprise) and system updates. If you don't find the option, try searching for it in Windows settings.
Remember that the quality of your WiFi signal is critical. If your router is located far away, use Wi-Fi analyzerto find a free channel and improve connection stability before you start transferring gigabytes of data.
Why does the speed constantly fluctuate when copying over WiFi?
Wi-Fi speeds are unstable due to interference from neighboring routers, microwave ovens, and physical obstacles. TCP/IP slows down when packets are lost to stabilize the connection. For stable speeds, use the 5 GHz band and move closer to the router.
Is it possible to transfer files if one computer is on Windows and the other is on macOS?
Yes, this is possible. On your Mac, you need to enable "File Sharing" in System Preferences. Windows will see your Mac as a network device. Accessing Windows from your Mac may require installing SMBv1 support (not recommended for security reasons) or properly configuring SMBv2/3 on Windows.
Is it safe to share personal photos through a shared folder?
This is safe within your home network, protected by a WPA2/WPA3 password. However, if guests or vulnerable smart devices are connected to your network, there is a risk. For sensitive data, it's best to use a password-protected archive or specialized encryption software.
