How to Transfer Data Between Laptops via WiFi: A Complete Guide

The modern pace of life requires instant data exchange, and wires for this have long become a relic of the past. Transfer files wirelessly It's not only convenient, but often the only possible solution when a flash drive or external hard drive is unavailable. Many users still seek complex workarounds, even though Windows and macOS operating systems offer built-in tools for creating local networks that are faster than cloud storage and don't require an internet connection.

In this article, we'll cover all the current methods for synchronizing data between two computers. You'll learn how to set it up. shared folder In the classic Windows environment, we'll use the quick sharing features in Windows 10 and 11, and we'll also explore cross-platform solutions. Transfer speeds on a local network can reach tens of megabytes per second, significantly exceeding Bluetooth or free cloud service plans.

The main advantage of this method is its complete autonomy. You don't need a router with internet access; the devices need to be on the same local network or directly connected. This is especially relevant for offices where gigabytes of source files need to be transferred, or at home when you need to copy a movie collection to another computer without losing quality.

Preparing equipment and checking the network

Before you begin configuring the software, you need to ensure the hardware is physically ready. Both laptops must be turned on and connected to the same wireless network. Wi-FiIf you're outside the router's range, you can set up a direct computer-to-computer (Ad-Hoc) connection, but for stable operation, it's better to use an access point.

The network profile type is critical. The operating system must recognize the network as "Private" and not "Public." For security reasons, the system blocks the device's visibility to other users when using a public profile, preventing file sharing. You can check this in the network settings by clicking on the connection properties.

⚠️ Warning: If one of the laptops uses an antivirus with a built-in firewall or a third-party firewall, it may block the connection even if Windows is configured correctly. Temporarily disable the protection to test or add an exception for the local network.

Also, make sure network discovery is enabled on both devices. Without this setting, the computers simply won't see each other in the list of available devices, and any further actions will be useless. This is a basic setting that's often ignored, wasting time troubleshooting non-existent problems.

Setting up a shared folder in Windows 10 and 11

The classic method, which works on all versions of Windows since Windows 7, is creating a shared folder. This method is ideal for regularly sharing documents in the office or between home computers. You don't need to reconfigure the connection each time; you only need to specify the directory path once.

To begin, select the folder you want to share with other users. Right-click it and select "Properties." Go to the "Sharing" tab and click "Sharing." In the window that opens, select a user (for example, "Everyone" or a specific system user) and set the permission level: "Read" will only allow copying files, while "Read and Write" will allow editing and deleting contents.

After setting up the permissions, you need to copy the network path to the folder. It usually looks like this: \\ComputerName\FolderName or \\192.168.1.5\FolderNameOn the second laptop, open File Explorer, enter this path in the address bar, and press Enter. The system may request the username and password for the account on the first computer—this is the standard authorization procedure.

It's important to understand the difference between access rights. If you're sharing confidential documents, don't grant access to the "Everyone" group; instead, create a specific user with a password. This will add a layer of security, as access to the shared folder will require credentials known only to you.

Nearby Sharing

More modern versions of the operating system, such as Windows 10 and 11, now feature a convenient "Nearby Share" feature. It works similarly to AirDrop across devices. Apple and allows you to transfer files and links via Bluetooth and Wi-Fi Direct without complicated network setup. This method is ideal for quick, one-time transfers of documents or photos.

To activate the function, go to “Settings” (can be accessed via Win + I), then select "System" and find the "Sharing" or "Nearby Sharing" section. Make sure the switch is set to "On." You can also adjust the visibility here: "Only my devices" (requires signing in to a single Microsoft account) or "Everyone nearby" (visible to everyone within range).

The transfer process is extremely simple. Select the file in File Explorer, right-click, and select "Share." The second laptop should appear in the list of available devices. After the receiving end confirms the request, the transfer will begin. Speed ​​depends on the power of the Wi-Fi modules, but is usually higher than Bluetooth.

Why isn't the Nearby Share feature working?

The feature may not activate if Bluetooth is disabled on one of the devices or the network card drivers are out of date. Also, make sure both computers are using the same Microsoft account or are in the same workgroup. Restarting the Function Discovery Service in Task Manager can sometimes help.

It's worth noting that Nearby Sharing requires both devices to support the Wi-Fi Direct standard. Very old laptops (manufactured more than 10 years ago) may lack this technology in their hardware, and the feature will be unavailable even with a system update.

Using cloud storage as an intermediate link

While the question is about local WiFi transfers, cloud services that use an internet connection shouldn't be ignored. For small files, this is often the fastest method, requiring no network configuration. Cloud synchronization (OneDrive, Google Drive, Yandex.Disk) happens automatically when there is a connection.

The method is simple: you upload a file to a cloud folder on the first laptop, and it automatically appears on the second one if the cloud service client is installed and logged in. This is convenient because files don't take up space on both devices simultaneously if Files On-Demand is enabled.

However, this method has a significant drawback: speed is limited by your internet service provider's plan and the speed of your cloud storage servers. If you need to transfer 50 GB of data, it's easier and faster to use a local network, as the cloud will load up your bandwidth and may require additional bandwidth charges.

Third-party programs for fast transfer (P2P)

If Windows' built-in tools seem cumbersome, specialized utilities come to the rescue. The leader in this niche is Send Anywhere or Resilio SyncThey create a direct P2P connection between devices, using the WiFi router only as a switch, without uploading files to third-party servers.

These programs often work by generating a six-digit key. You select files on the first laptop, and the program generates a code. You enter this code on the second device, and direct transfer over the local network begins. This combines the simplicity of cloud services with the speed of a local connection.

Another popular option is the utility Feem or Dukto (and its forks). They require no installation, are portable, and automatically discover devices on the network. The interface of such programs typically consists of a list of available computers and a drag-and-drop area.

The advantage of third-party software is its cross-platform compatibility. You can easily transfer files not only between Windows laptops, but also to an Android smartphone, iPhone, or Mac, as long as they have the appropriate app installed or the receiver's web interface is open.

Organizing a home network and troubleshooting

Even with proper configuration, situations may arise where computers cannot see each other. One common cause is different workgroups. By default, Windows uses a workgroup WORKGROUPYou can check and change this in "System Settings" -> "Computer Name." The workgroup names must match on both devices.

It's also worth paying attention to Windows services. The services responsible for network discovery are "Function Discovery Resource Publishing," "SSDP Discovery," and "Discovery Provider Host Device." If they are stopped, the network will not function. You can check their status by entering the command services.msc in the Run menu.

⚠️ Note: Network settings interfaces may vary depending on your Windows version (Home, Pro, Enterprise) and installed security updates. If you can't find the option, try searching for keywords in the system settings.

If all else fails, try temporarily disabling IPv6 in your network adapter's properties. Sometimes the new-generation protocol conflicts with older router hardware, causing visibility issues on the local network. Leave only the "Internet Protocol Version 4 (TCP/IPv4)" checkbox checked.

Comparison of methods and selection of the optimal solution

Which method should you choose? For a one-time transfer of photos from your phone or a couple of documents from another laptop, Nearby Share or messaging apps are ideal. They're fast, require no setup, and work out of the box.

If you regularly work with large amounts of data, such as editing video or processing graphics, setting up a permanent shared folder (SMB) will be the most efficient solution. It provides stable speed and access to files as if they were local, without having to initiate transfers each time.

For a mixed fleet of devices (Windows, macOS, Linux, Android), cross-platform solutions like Resilio Sync Or setting up a NAS (network-attached storage), although the latter goes beyond simply connecting two laptops. The main thing to understand is that WiFi, while convenient, has limitations in speed and signal stability compared to cable.

Is it possible to transfer files if the router is turned off?

Yes, you can. To do this, you need to create a direct wireless connection (Ad-Hoc network) on one laptop and connect to it from the other. However, in Windows 10/11, creating such a network through the graphical interface is hidden, and you may need to use the command line or third-party software to create a virtual access point.

Why is my WiFi transfer speed low (less than 1 MB/s)?

Low speeds can be caused by using the 802.11b/g WiFi standard (on older routers), high noise levels from neighbors, or one of the laptops being too far from the router. Speeds can also be reduced if WEP encryption is used or if the laptop's processor can't handle the traffic encryption.

Is it safe to share passwords through a shared folder?

Transferring files within a closed home network is relatively secure, but it's not recommended to transfer files with passwords in plaintext if others have access to your WiFi network. It's better to use password-protected archives or dedicated secure communication channels.
