Transferring large amounts of data between computers without external drives is a challenge every user faces. Modern laptops are equipped with powerful wireless modules, allowing for high-speed data transfer without the need for unnecessary wires. The operating system Windows 10 This process is implemented quite flexibly, offering several operating scenarios depending on your needs.
The main advantage of using a local network is the elimination of the need for a flash drive or cable, as well as the ability to transfer files tens of gigabytes in size without depending on internet bandwidth. Local data exchange works directly between devices, ensuring maximum speed, limited only by the capabilities of your router and network cards. This is especially true for owners of older laptops, whose USB ports may be slow.
In this article, we'll take a detailed look at all current transfer methods, from the classic shared folder to the built-in Nearby Sharing feature. You'll learn how to properly configure network discovery, avoid common access errors, and optimize settings for optimal performance. Network readiness is key to success.
Basic network setup in Windows 10
Before you begin transferring data, you need to ensure both laptops have equal visibility. By default, Windows security can hide your computer from other devices if the network profile is set to "Public." To get started, you need to change this setting to "Private Network" on both devices to allow the exchange of service packets.
Open the Start menu and go to Settings, then select Network & Internet. In the properties of your active connection (Wi-Fi), find the network profile switch. This is where you set the mode in which your laptop becomes visible to others. local networkWithout this step, any further steps to search for devices will be useless.
The next important step is enabling network discovery. This feature allows your computer to not only see other devices, but also be visible to others. In the Network and Sharing Control Panel, find the "Advanced Sharing Settings" section. Here, enable "Turn on network discovery" and "Turn on file and printer sharing."
⚠️ Warning: Enabling sharing in unfamiliar places (cafes, airports) can expose your data. Use these settings only on trusted home or office networks.
It's also worth paying attention to your power settings, as Windows may disable the wireless adapter to save power, which will cause the connection to drop during transmission. Go to Device Manager, find your Wi-Fi adapter, open its properties, and in the Power Management tab, uncheck the box next to Allow the device to turn off.
Organizing exchange through a shared folder
The classic method, which remains one of the most reliable and fastest, is creating a shared folder. This method doesn't require installing third-party software and operates at the protocol level. SMBThe algorithm is simple: you create a folder, grant access to it for network users, and then copy the files you need to transfer into it.
To configure access, create a new folder or select an existing one, right-click it, and select "Properties." Go to the "Sharing" tab and click "Advanced." In the window that opens, check "Share this folder" and click "Permissions." Allow "Everyone" either full access or read-only access, depending on your needs.
What should I do if the folder won't open over the network?
If you receive an access error when trying to sign in, check your password settings. Windows 10 has password protection enabled by default. Either disable it in the Network and Sharing Center (under "Password-protected sharing"), or create identical accounts with the same passwords on both laptops.
After setting up the folder on the first laptop, go to the second one. Open "This PC" and enter the name of the first computer or its IP address in the address bar of File Explorer in the format \\ComputerName or \\192.168.1.XXIf everything is done correctly, you will see the shared folder and be able to copy files from it at high speed.
☑️ Checking shared folder settings
It's important to understand that the copy speed in this case will depend on the signal stability and Wi-Fi standard. If your router supports dual-band mode, make sure both laptops are connected to the network. 5 GHz, as this will provide significantly higher throughput compared to the 2.4 GHz band.
Using Nearby Sharing
Newer Windows 10 builds now feature a native feature similar to AirDrop in the Apple ecosystem. Called Nearby Share, it lets you transfer files and links via Bluetooth and Wi-Fi Direct without the need for complex network setup. It's ideal for quickly sending a single document or photo.
To enable this feature, open Settings (Win+I), go to System, and find Nearby Sharing. Make sure the toggle is set to On. You can also adjust the visibility here: select "Everyone" if you trust devices within range, or "My devices only" if both laptops are signed in to the same Microsoft account.
The transfer process is extremely simple: right-click the file and select "Share" from the context menu. The system will begin searching for available devices nearby. Once the second laptop's name appears, click it, and a notification will appear on the target device asking if you want to accept the file.
It's worth noting that this technology is most effective over short distances, as Bluetooth Low Energy is often used for the initial handshake. If the files are very large, the speed may be lower than when using a shared folder due to the overhead of the encryption and search protocol.
Transferring files via FTP server
For advanced users who need to regularly transfer large amounts of data or manage files remotely, deploying an FTP server on one of their laptops is an excellent solution. This method ensures a stable connection, the ability to interrupt and resume downloads, and is unaffected by the vagaries of the Windows network environment.
Windows 10 already has a built-in IIS (Internet Information Services) component that can function as an FTP server, but setting it up is quite complex for a beginner. It's easier to use lightweight free utilities, such as FileZilla Server Or even the built-in capabilities of some file managers. After installing the program, you'll need to specify the root folder where the recording will take place and set access rights.
On the receiving laptop, simply open any browser or explorer and enter the address in the format ftp://server-ip-addressIf you've configured the server correctly, the system will prompt you for a login and password, after which you'll be able to access the file system like a regular disk. This allows you to drag and drop files.
⚠️ Note: By default, the FTP protocol transfers data in cleartext, including passwords. Use this method only within your secure home network. For internet transfers, be sure to configure FTPS (FTP over SSL).
The advantage of this approach is its independence from Windows versions. You can transfer files from a Windows 10 laptop to a Linux, macOS, or even Android laptop using a universal protocol. This makes the method extremely flexible in mixed ecosystems.
Comparison of methods and selection of the optimal solution
The choice of a specific transfer method depends on many factors: file size, frequency of operation, and your level of technical expertise. To make your decision easier, we've summarized the key characteristics of the methods considered in the table below.
For one-time, small-volume operations (photos, documents), "Share with others" or even instant messaging apps are best, if you have internet access. However, if you need to transfer archives weighing 50-100 GB, then a shared folder or FTP is essential, as they provide the best transfer speed. data flow stability.
| Method | Speed | Difficulty of setup | Best use |
|---|---|---|---|
| Shared folder (SMB) | High | Average | Regular work with large files |
| Exchange with the environment | Average | Low | Quick transfer of photos and documents |
| FTP server | Very high | High | Professional work and remote access |
| OneDrive / Cloud | Depends on the Internet | Low | Synchronization of small volumes |
Keep in mind that wireless network performance is directly dependent on airwave congestion. If your router is in an apartment with dozens of neighboring networks, speeds may drop. In such cases, using a LAN cable for initial setup or critical transmissions remains the most reliable, albeit less convenient, option.
Solving common connection problems
Even with proper configuration, users often encounter a situation where computers can't see each other. The most common cause is Windows services that have stopped for some reason. Check the Discovery Resource Publishing service and the SSDP Discovery Manager service. They should be running and running automatically.
Another common culprit is your antivirus or built-in firewall. They may block incoming connections, deeming them suspicious. Try temporarily disabling your third-party antivirus or adding your network connection to the trusted list in Windows Firewall settings. This often resolves the visibility issue immediately.
If computer names contain Cyrillic characters or special characters, name resolution conflicts may occur. In this case, use the IP address to connect. You can find it by opening the command prompt (press Win+R, enter cmd) and running the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter.
In some cases, simply restarting the Network Discovery service helps. Open the service (command services.msc), find the desired one, right-click it, and select "Restart." This resets the discovery cache and forces the system to rescan the network.
Optimizing wireless transmission speed
To get the most out of your hardware, make sure your Wi-Fi adapter drivers are updated to the latest version. Manufacturers frequently release updates that improve connection stability and network speed. 802.11ac or axOld drivers may not work correctly with new encryption standards.
It also makes sense to disable power saving for the USB ports and the adapter itself, as mentioned earlier, but also disable "Power Saving Mode" in the Wi-Fi module's properties in Device Manager. This will prevent micro-disconnections, which significantly slow down the copying of many small files.
If you're using the shared folder method, you can try adjusting the MTU packet size, although the default values are optimal in most cases. It's more effective to close background applications that consume bandwidth, such as torrents, streaming services, or cloud syncing apps, while transferring important data.
⚠️ Note: Operating system interfaces and menu item names may vary slightly depending on the Windows 10 build version (21H2, 22H2, etc.). If you can't find the item, try searching for it in your system settings.
Keep in mind that the actual Wi-Fi transfer speed will always be lower than the theoretical speed of your internet plan or router rating. Data transmission protocols have overhead, and the radio signal is subject to attenuation. However, a properly configured local network can achieve speeds of 30-50 Mbps or higher, which is quite sufficient for comfortable work.
Why can't my laptop see another laptop on the network?
Most often, the problem lies with the "Public" network profile. Switch it to "Private" in the Wi-Fi settings. Another cause is a disabled network discovery service or a firewall blocking it. Also, make sure the workgroup names on both computers match (by default, it's "WORKGROUP").
What is the maximum transfer speed for Wi-Fi?
In the 2.4 GHz band, actual speeds rarely exceed 3-5 MB/s. In the 5 GHz AC band, speeds of 20-40 MB/s can be achieved, and when using the new AX (Wi-Fi 6) standard and in close proximity, speeds of up to 80-100 MB/s are comparable to fast flash drives.
Is it safe to transfer files through a shared folder?
Within your home network, yes. However, if you're connected to public Wi-Fi, enabling network sharing makes your files vulnerable. In such cases, use a VPN or temporarily disable network discovery.
Is it possible to transfer a file from Windows 10 to Mac via Wi-Fi?
Yes, macOS supports the SMB protocol. On a Mac, in Finder, select "Go" -> "Connect to Server" and enter the address of the Windows machine. You will be asked to enter your Windows username and password.
