Modern users rarely work with just one device. They often need to urgently transfer photos from their work computer to their home laptop or copy a large project to a colleague. Using USB flash drives seems archaic, and the speed of a wired connection isn't always available. This is where wireless networking comes in, eliminating the need for cables.
Data transfer by local network It's not magic, but a standard operating system feature that's often hidden from the average user. Many people mistakenly believe it requires complex programs or paid software. In fact, built-in Windows and macOS tools allow you to set up file sharing in minutes, if you know where to find the right settings.
In this article, we'll explore proven methods that work reliably and don't require extensive networking knowledge. You'll learn how to create a direct connection, how to properly configure folder access, and what nuances affect copy speed. The key is that both devices must be on the same network or have a direct connection configured.
Preparing equipment and checking network settings
Before you begin setting up the exchange, you need to make sure that both laptops are in the same connection conditions. The ideal scenario is when both devices are connected to the same router via Wi-Fi. If you're using a public network at a cafe or office, the system administrator may have blocked file sharing between clients, and this method won't work.
The second important point is the network profile. Windows treats new connections as "Public" by default, which automatically hides your computer from other devices for security reasons. You need to change this status to "Private Network." Without this step, the laptops simply won't see each other, no matter how hard you try to find them.
⚠️ Attention: Switching your network profile to "Private" in places like cafes and airports makes your computer visible to other users. Only do this on trusted home or office networks.
It's also worth checking if network discovery is enabled. This is a basic protocol that tells the system to search for other devices and allow them to see it. Without active network discovery, all further settings will be useless.
☑️ Check before you start
Make sure both laptops have the latest drivers for their Wi-Fi adapters. Old wireless module software can become unstable under heavy loads, which occurs when transferring large amounts of data. Updating drivers often resolves issues with connection drops mid-connection.
Setting up a shared folder and access rights in Windows
The most reliable and fastest way to transfer files is to use the built-in "Sharing" feature. You don't need to download anything, as this mechanism is deeply integrated into the file system. First, create a folder in which you plan to store the files for transfer, or select an existing one.
Right-click the folder and select "Properties." Go to the "Sharing" tab and click "Advanced." Here, check the box next to "Share this folder." Then click "Permissions" to determine what other users can do with these files.
In the window that opens, you'll see a list of groups. By default, it may be labeled "Everyone." Select it and check the boxes next to "Full Control," "Modify," and "Read." This will allow the second laptop not only to retrieve files but also, if necessary, to write new data to this folder. Be sure to click "Apply" and "OK" in all open windows.
However, access settings are only half the battle. The system often blocks connections due to password protection settings. If you don't want to enter your account login and password every time, you can disable this feature, but only on a secure home network.
Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsUnder "All Networks," find "Password-protected sharing" and select "Turn off password-protected sharing." This will simplify the connection, as the second laptop will be able to access your folder without additional authorization.
What to do if Windows requires a password?
If disabling protection doesn't help, try creating a new local user with a simple password (e.g., 12345) on both computers. The account credentials must match. This is an old but effective trick for bypassing authentication errors on local networks.
After all these steps, the folder will be available in the "Network" section on the second computer. If you don't see it immediately, you may need to restart both devices or refresh the list of network resources.
Use Nearby Share for quick sharing
Newer versions of Windows 10 and 11 have a feature Nearby Sharing (Nearby Sharing), which works similarly to AirDrop on Apple devices. This method is ideal for quickly transferring individual documents or photos without creating complex network structures and shared folders.
This technology uses a combination of Wi-Fi Direct and Bluetooth. Devices find each other automatically when they are close enough. You don't need to know IP addresses or computer names—the system will automatically suggest a list of available devices.
To activate this feature, go to "Settings" (the gear icon in the Start menu), then select "System" and find "Nearby Sharing." Turn the toggle to "On." Here you can also configure who can send you files: everyone around you or just your devices.
⚠️ Attention: Transfer speeds via Nearby Sharing may be slower than using a shared folder due to the discovery protocols involved. For files tens of gigabytes in size, the shared folder method is better.
The transfer process is intuitive: right-click the file, select "Share," and you'll see the second laptop's name in the list of available devices. A notification will appear on the receiving end asking if you want to save the file. Once confirmed, the download will begin.
The advantage of this method is its portability. If you're away from home and don't have access to a router, but your Wi-Fi adapters are working, you can still transfer the file, as the laptops will create a direct connection between them.
Data transfer via cloud storage and web services
Sometimes fiddling with network settings is either impossible or time-consuming due to corporate restrictions. In such cases, cloud technologies come to the rescue. Although technically this transfer occurs over the internet rather than directly over Wi-Fi, the end result for the user is the same: the files end up on another device.
The easiest option is to use services like Google Drive, Yandex Disk or DropboxYou upload a file from one laptop to the cloud, and download it from the other. The speed is limited by your provider's plan and the speed of the cloud storage servers.
There are also specialized web services for fast transfer, such as WeTransfer or Send AnywhereThey don't require registration. You go to the website, upload the file, receive a link or code, enter it on the second laptop, and download the data.
| Method | Speed | Internet access is needed | Size limit |
|---|---|---|---|
| Local Area Network (SMB) | High (depending on the router) | No | No |
| Nearby Exchange | Average | No | No |
| Cloud storage | Depends on the tariff | Yes | Depends on the service |
| Telegram (Favorites) | Average | Yes | 2 GB per file |
It's important to note that when using cloud-based methods, you essentially upload data twice: first to the server, and then the server sends it to the other device. This consumes bandwidth and time, but eliminates the need to configure access rights and IP addresses.
For regular work with large amounts of data, cloud storage can be inconvenient due to storage limitations. However, for documents and photos, it's one of the most convenient ways to sync between laptops.
Direct laptop-to-laptop connection (Ad-Hoc and hotspot)
If you don't have a router handy but need to transfer files, you can set up a direct connection between two laptops. One laptop acts as an access point (hotspot), and the other connects to it as a regular Wi-Fi network. This creates a local network without the need for external equipment.
In Windows 10 and 11, this is done via "Mobile Hotspot." Go to Settings → Network & Internet → Mobile Hotspot. Select the network you want to share (usually Wi-Fi) and enable the feature. On the second laptop, find the newly created network in the list of available Wi-Fi networks and connect using the password.
Once connected, you can use the methods described in the section on shared folders. Your computers are now on the same network, even if they aren't connected to the internet. Transfer speeds in this mode depend on the quality of your Wi-Fi adapters and the distance between the devices.
The old method of creating an ad-hoc network via the command line is now less common, as the hotspot interface has become more user-friendly. However, if you have older Windows 7 laptops, this command may still be useful:
netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=parol123This command creates a virtual adapter that allows you to start the network. After starting (netsh wlan start hostednetwork) you will also need to set up sharing in the network connection properties, allowing other network users to use this computer's Internet connection.
Keep in mind that when using a Wi-Fi hotspot, a laptop will consume more power. If the battery is critically low, it's best to plug the device into a power outlet before starting a long file transfer.
Typical problems and solutions
Even with proper configuration, errors may still occur. The most common issue is "Windows cannot access the network path." This is often due to ports being blocked by an antivirus or firewall. Try temporarily disabling your third-party antivirus and checking for access.
Another common issue is slow copy speeds. If files of several gigabytes are copied at a speed of 1-2 MB/s, the problem may be with the Wi-Fi standard. If your router supports 5 GHz, and laptops are connected to 2.4 GHz, the speed will be limited by interference and congestion in the range.
It's also worth checking whether the "Power Saver" feature for the Wi-Fi adapter is enabled on one of your laptops. In power saving mode, the adapter may reduce signal strength or go into sleep mode, interrupting data transfer.
⚠️ Attention: Settings interfaces and menu item names may vary depending on the Windows version (10, 11) and system updates. If you don't find an exact match, look for similar options in the network settings section.
If none of these methods work, try temporarily disabling IPv6 in your network adapter properties. Sometimes IPv6 conflicts with your home network settings, and disabling it resolves the visibility issue.
As a last resort, you can use third-party file transfer programs such as Feem or DuktoThey create their own network over Wi-Fi and often work where standard Windows tools fail.
Do I need internet access to transfer files via Wi-Fi?
No, internet access is not required. For a local network (SMB) or the "Nearby Sharing" feature to work, devices must be connected to the same router or directly. In this case, the router simply acts as a switch, forwarding data between devices within your network without accessing the global network.
Why is file transfer so slow?
Speed depends on several factors: the Wi-Fi standard (802.11n, ac, ax), distance to the router, the number of obstacles (walls), and channel congestion. Speed may also drop if one of the laptops is running in power-saving mode or has an older Wi-Fi adapter.
Is it safe to transfer files through a shared folder?
On a home network, yes, it's safe. In public places (cafes, hotels), using shared access without a password is dangerous, as intruders on the same network could access your files. In such cases, it's better to use a direct connection or encrypted archives.
Is it possible to transfer data between Windows and macOS?
Yes, you can. Both macOS and Windows support the SMB protocol. From a Mac, you can connect to a Windows shared folder via Finder (Command → Connect to Server → smb://IP Address). Conversely, you can access a Mac shared folder from Windows.
