Modern users often face the need to urgently exchange data between devices when a flash drive is not available and the internet connection is overloaded. Transferring gigabytes of photos, work projects, or large archives to a neighboring computer is becoming a common occurrence. Using a local wireless connection in such cases is the most logical and effective solution, eliminating the hassle of cables.
There are many methods for accomplishing this task, from built-in system utilities to specialized software. The choice of a specific method depends on the operating system version, the availability of administrator rights, and the transfer speed requirements. Local area network (LAN) over the air provides a stable communication channel that often outperforms older USB drives.
In this article, we'll explore proven workflows that guarantee successful data transfer. You'll learn how to set up sharing, use built-in Windows tools, and apply third-party utilities for maximum efficiency. The key is to choose the option that best suits your current hardware configuration.
Using Nearby Share in Windows 10 and 11
Starting with Windows 10, the operating system includes a native tool for quick file sharing. This feature, known as Nearby Sharing, uses a combination of Bluetooth for device discovery and WiFi for direct data transfer. The technology allows you to send documents, links, and images to any laptop within wireless range.
To activate, you need to open the system settings via Start → Settings → SystemIn the left-hand menu, select "Nearby Share" and toggle the switch to "On." You can also configure visibility here: "Only My Devices" will allow data transfer between devices logged in with the same Microsoft account, while "Everyone Around Me" will make the laptop visible to all nearby devices.
- 📂 Open the file you want to send and click the "Share" button.
- 📡 The system will automatically scan the air and display available laptops in a list.
- ✅ The recipient will see a pop-up notification and must confirm receipt of the data.
- 📂 Files are saved to the Downloads folder by default.
The transmission speed using this method varies and depends on the quality of the router signal. Bluetooth Low Energy Here, it's used only for handshake purposes, so most traffic goes over the WiFi channel, ensuring decent performance. However, for large amounts of data, this method may not be the fastest compared to setting up a full-fledged shared folder.
Setting up a shared folder on a local network
The classic method remains the most reliable for regularly working with large amounts of information. Sharing a folder allows you to access files on another computer as if they were locally stored. For proper operation, both laptops must be connected to the same WiFi network, preferably in the 5 GHz band for maximum throughput.
The first step is to ensure that the network profile is set to "Private Network." If the system considers the network to be "Public," it will block device discovery for security reasons. Go to Settings → Network & Internet → Ethernet/WiFi and change the profile type. After that, you need to enable network discovery in "Sharing options."
⚠️ Caution: Enabling sharing on unsecured public networks (such as cafes and airports) can expose your data to unauthorized access. Use this method only on trusted home or office networks.
Next, select the folder you want to share. Right-click it, select "Properties," and go to the "Sharing" tab. Click "Sharing" and add the user "Everyone," assigning them "Read and Write" permissions. This will allow the second laptop to not only open files but also write new ones.
☑️ Shared Folder Setup Checklist
To access resources from another device, open File Explorer and go to the Network section. If the computer doesn't show up immediately, you can enter its IP address in the address bar in the format \\192.168.1.XXYou can find out your IP address through the command line by entering the command ipconfigWhen connecting for the first time, the system may request the login and password of the host computer account.
Transfer via the built-in Nearby Sharing feature
An alternative to traditional folder sharing is to use the quick access feature integrated into the Windows context menu. This method is convenient because it doesn't require complex pre-configured access rights for each individual directory. It's ideal for one-time transfers of documents or media files to colleagues or family members.
The process is launched directly from the file's context menu. Right-click the object, select "Share," and wait for a list of available devices to appear. SMB protocol, used in the background, ensures the integrity of transmitted data. If the device is not found, check that discovery is enabled in the network settings.
| Parameter | Shared folder | Exchange with the environment |
|---|---|---|
| Difficulty of setup | High | Low |
| Speed of work | Maximum | Average |
| Suitable for | Permanent work | One-time shipments |
| Requires a password | Often | Rarely (depending on settings) |
It's important to note that both laptops must be unlocked when using this method. If the target device is in sleep mode, the transfer won't begin until it wakes up. Also, keep in mind that antivirus software on the receiving end may block incoming connections, requiring manual confirmation.
What to do if computers can't see each other?
Often, the problem lies with the Function Discovery Resource Publishing service. Press Win+R, enter services.msc, find this service, and make sure it's running. Also, try rebooting the router.
Using third-party utilities for fast transfer
When built-in Windows tools cause problems or become unstable, specialized programs come to the rescue. The leader in this niche is the utility ShareIt or its open analogues like LocalSendThese applications create their own temporary network or use the HTTP protocol to transfer data, bypassing system restrictions.
The principle behind these programs is simple: a client application is installed on both laptops. Once launched, the program scans the network and finds other devices running the client. The key advantage of such solutions is their cross-platform nature: you can easily transfer a file from Windows to macOS, Linux, or even Android without any additional configuration.
- 🚀 High transfer speed, often higher than standard Windows tools.
- 🔒 Traffic encryption (in some apps) to protect data.
- 📱 Possibility of transfer to mobile devices on the same network.
- 🚫 No need for complex settings of access rights and passwords.
Some utilities, for example, Feem or Send Anywhere, allow you to transfer files even without a direct connection to a single router, using WiFi Direct technology. In this case, one laptop creates an access point to which the other connects. This is especially useful in situations where the central router is temporarily unavailable or overloaded.
Setting up a WiFi Direct connection
Technology WiFi Direct Allows devices to connect directly to each other without the need for a wireless router. This creates a virtual communication channel that works even without internet access. This method is especially useful in field settings or offices where there is no access to an infrastructure network.
To implement this method in Windows 10 and 11, you can use the "Mobile Hotspot" feature. Enable it in the network settings by selecting "None" as the connection source or using an existing internet connection. The second laptop should find the created network in the list of available WiFi connections and log in using the password specified in the hotspot settings.
Once connected, the laptops are connected to the same local network, and all file transfer methods described above are available: shared folders, FTP servers, or specialized software. Connection speeds in Direct mode are often higher than through a standard router, since the bandwidth isn't shared among multiple devices.
⚠️ Note: When using access point mode, the host laptop may limit the number of simultaneous connections. Make sure your WiFi adapter drivers support SoftAP mode.
Power consumption should be considered: access point mode consumes more battery power. If you're using battery power, monitor the battery level. Furthermore, the frequency range may be limited by the network adapter's capabilities, which affects the overall channel throughput.
Solving common connection problems and errors
Despite its apparent simplicity, setting up wireless data exchange can encounter technical obstacles. Most often, the problem lies in the Windows Firewall settings, which by default blocks incoming connections on public networks. You should add an exception rule for the SMB protocol (port 445) or temporarily disable the firewall to test the connection.
Another common cause is different SMB protocol versions. Older laptops may use SMBv1, which is disabled by default in newer versions of Windows for security reasons. You can enable support via Control Panel → Programs and Features → Turn Windows features on or off, but do so with caution.
Get-SmbServerConfiguration | Select EnableSMB1Protocol
This PowerShell command will check the support status of the old protocol. If the issue persists, try updating your network adapter drivers. Hardware manufacturers regularly release updates that improve connection stability and compatibility with new encryption standards.
Why does the speed drop during transmission?
Speed may decrease due to interference in the air (microwaves, neighboring routers), using the 2.4 GHz band instead of 5 GHz, or background downloads on one of the devices.
If none of the above works, try resetting your network settings. In Windows 10/11, this can be done via Settings → Network & Internet → Advanced network settings → Network resetThis action will delete all saved WiFi passwords and reset network adapters to factory settings, which often resolves software conflicts.
Do you need internet access to transfer files via WiFi?
No, an internet connection is not required. For transmission, both devices must be connected to the same router (even without access to an external network) or directly via WiFi Direct. Local traffic does not travel outside your internal network.
What is the maximum transfer speed for WiFi?
Speed depends on the WiFi standard. For 802.11n (2.4 GHz), actual speeds rarely exceed 40-50 MB/s. The 802.11ac standard (5 GHz) allows for speeds of 300-500 MB/s and higher, comparable to fast USB drives.
Is it safe to share passwords over a shared network?
Sending passwords in cleartext over a local network is not recommended. Use secure protocols (SFTP instead of FTP) or encrypt file archives before sending, especially on office networks with a large number of users.
Why can't my laptop see another laptop on the network?
Make sure both devices are in the same network profile ("Private"), the discovery service is enabled, and the workgroups are the same. Your antivirus software may also be blocking the devices' visibility.
