In today's digital world, there's often a need to quickly transfer a large collection of photos, a video archive, or a heavy project from one computer to another. Using USB flash drives or external hard drives becomes inconvenient when you need to work continuously, and cloud storage can be limited by internet speed or file size. It's in these situations that a direct connection between devices becomes the most effective solution.
Connecting two laptops wirelessly Wi-Fi Allows you to create a local environment where data transfer speed is limited only by the capabilities of your router and network adapters. This method doesn't require purchasing additional equipment if both devices are already connected to the same access point. In this article, we'll cover all the setup details, from simple methods to creating direct computer-to-computer connections.
There are several proven methods for accomplishing this task, each with its own advantages depending on your operating system and security requirements. You can use built-in Windows tools, such as Sharing, or turn to third-party software to simplify the process. Understanding the principles local network will help you not only transfer files, but also organize collaborative work on documents or even launch an online game.
Preparing equipment and checking the network
Before beginning complex setup, ensure the basic infrastructure is ready. Both laptops must be powered on and within range of a strong signal. If you're using a home router, ensure both devices are connected to that router's network, not to a guest or neighbor's access point.
Checking the network type is crucial. Windows assigns new connections the "Public Network" profile by default, which prevents your device from being visible to others. You need to change this status to "Private Network" on both computers for the system to allow discovery. This can be done through the Network and Sharing Center or through a pop-up notification when you first connect.
- 📡 Make sure both laptops are connected to the same router or are on the same subnet.
- 🔒 Make sure the network profile is set to "Private" and not "Public".
- 📶 It is advisable that both devices operate in the 5 GHz range for maximum data transfer speed.
It's also worth paying attention to your firewall settings. Sometimes antivirus software or the built-in Windows Defender can block incoming connections, deeming them suspicious. If, after adjusting all the settings, the computers still can't see each other, try temporarily disabling third-party firewalls for diagnostic purposes.
⚠️ Attention: When working in public places (cafes, airports), it is highly recommended not to enable file sharing, as this may make your data vulnerable to other network users.
Checking IP addresses is another important diagnostic step. The devices should have addresses in the same subnet, for example, 192.168.1.5 and 192.168.1.10. If the addresses are significantly different (for example, 192.168.0.x and 192.168.1.x), then a direct connection without routing is impossible.
Setting up sharing in Windows
After preparing the network, you need to enable the appropriate services in the operating system. Windows has flexible tools for sharing resources, but they are often disabled by default for security reasons. We'll need access to advanced sharing options.
To access the required menu, open Control Panel, go to Network and Internet, then Network and Sharing Center. On the left side of the window, select Change advanced sharing settings. This is where you'll find the key switches that control your laptop's visibility.
In the window that opens, for the current profile (Private), you must perform the following actions:
- ✅ Turn on network discovery so other computers can see your laptop.
- ✅ Enable file and printer sharing.
- ✅ Allow Windows to manage HomeGroup connections (if used).
The "All Networks" section deserves special attention. It's recommended to enable sharing here so that any network user can access shared folders. However, if you're sharing sensitive data, it's best to leave password protection enabled. This will require entering the username and password for the user account when connecting from another laptop.
After changing the settings, be sure to click "Save Changes." Sometimes a system reboot or reconnection to Wi-Fi is required for the new settings to take effect. Without this step, even correctly configured folders may remain invisible.
Creating a shared folder and sharing resources
Once the network infrastructure is set up, you need to select the specific data you want to share. Simply opening the entire C: drive is neither possible nor necessary. We'll create or select an existing folder and configure its access rights.
Create a new folder on your desktop or at the root of your drive, name it something like, ExchangeRight-click on it and select "Properties." You'll need to go to the "Sharing" tab. Click "Advanced" and check "Share this folder."
Next, you need to configure user permissions. Click the "Permissions" button. By default, it may be labeled "Everyone." Select it and check the boxes for the desired actions: "Read" (if you only need to download files) or "Full Control" (if you also need to write and modify files on the remote computer).
Don't forget to also check the "Security" tab in the folder properties. The user should be added there. Everyone or a specific user with read and write permissions. If this isn't done, the system may allow the user to access the network but block access to files at the NTFS file system level.
| Access type | Description of rights | Recommended use |
|---|---|---|
| Reading | The user can only open and copy files. | Transfer of documents, photos, videos |
| Change | The user can edit and delete files | Collaborating on a project |
| Full access | All rights, including changing access rights | Administration, full synchronization |
Once configured, the folder will be accessible over the network. To find it on the other laptop, open File Explorer, go to the Network section, and find the name of the first computer. If the system prompts for a password, enter the user account information for the first laptop.
Using Nearby Share
Windows 10 and 11 introduce a more modern and simple alternative to classic folder sharing: Nearby Sharing. It works similarly to AirDrop on Apple devices and allows you to transfer files in a few clicks without setting up complex paths.
To activate this function, go to “Settings” (keys Win + I), select "System" and find "Nearby Sharing." Turn the switch to "On." Make sure Bluetooth and Wi-Fi are also allowed in the settings.
The transfer process is as follows:
- Open the file you want to share, or right-click the file and select Share.
- In the list that appears, select the name of the second laptop.
- A notification will pop up on the second device asking you to accept the file.
This method is ideal for quickly transferring small and medium-sized files. It doesn't require creating shared folders or entering passwords if the devices have previously communicated with each other. However, for transferring hundreds of gigabytes of data, the shared folder method is better, as it's more stable during connection interruptions.
It's important to note that this feature may not work on older versions of Windows or if the wireless adapter drivers are out of date. In such cases, the system may prompt you to update the drivers or simply not display the target device in the list of available devices.
Setting up a network without a router (Ad-Hoc)
Situations vary: you might be in a field, on a train, or your router might have suddenly broken down and you need to transfer files. In this case, you can create a direct wireless connection between laptops, turning one of them into an access point.
Modern Windows makes it easy to set up a mobile hotspot. On the first laptop (which will be the "server"), go to "Settings" → "Network & Internet" → "Mobile Hotspot." Select a connection (e.g., Wi-Fi) and enable the feature. The system will display the network name and password.
The second laptop should find the created network in the list of available Wi-Fi connections and connect to it by entering the password. After that, you'll be connected to the same local network, even without internet access. You can then use the methods described in the sections above: sharing a folder or using an FTP server.
⚠️ Attention: Creating a hotspot on a laptop significantly increases battery consumption. It's recommended to connect devices to a power source during extended data transfers.
There's also an older method for creating a computer-to-computer (Ad-Hoc) network via the command line, but in Windows 10/11 it's often hidden or requires additional steps. Using the built-in mobile hotspot is a more reliable and compatible solution.
What should I do if the second laptop doesn't see the created network?
Make sure the receiving device isn't in airplane mode. Also, check if the second laptop's network adapter supports access point mode (although they typically operate as clients). Updating the Wi-Fi module drivers can sometimes help.
Alternative methods and third-party software
If Windows' built-in tools seem too complex or unstable, you can always turn to proven third-party solutions. They often offer a more user-friendly interface and additional features, such as traffic encryption.
One of the most popular solutions is the creation of FTP serversYou can install a lightweight FTP server (for example, FileZilla Server) on one laptop, share the desired folder, and connect to it on the second laptop via Explorer by entering the address ftp://IP addressThis gives excellent speed and control over the process.
Another option is to use synchronization programs such as Resilio Sync or SyncthingThey create a P2P connection between devices over a local network and synchronize specified folders. This is ideal for constantly working on the same projects from different devices.
Comparison of transmission methods:
- 🚀 SMB Shared Folder: Native to Windows, fast, but requires permissions configuration.
- 📤 Exchange with the environment: Very simple, but can be slow for large volumes.
- 📂 FTP server: Maximum reliability and speed, but requires software installation.
For one-time transfers of large files, programs like Send Anywhere or web services running on a local network (for example, Sharedrop.io). They do not require installation, work through a browser, and use WebRTC technology for direct data transfer between browsers.
Troubleshooting connection issues and errors
Even with careful configuration, errors can still occur. Computers may not be able to see each other, or access may be blocked. The most common cause is Windows services. Make sure the Function Discovery Resource Publishing service is running.
To check, open the Run window (Win + R), enter services.msc and find in the list:
- Function Discovery Resource Publication
- SSDP Discovery
- UPnP Device Host
For each of them, set the startup type to "Automatic" and click "Start." Without these services, the computer will not be able to properly advertise itself on the network.
Another common issue is time desynchronization. If the time and date on your laptops are significantly different, the Kerberos security protocol may block the connection. Make sure the time is consistent to within a few minutes.
☑️ Connection diagnostics
If all else fails, try temporarily disabling your antivirus software on both devices. It's often a "black box" that silently blocks network packets without warning the user.
Why is the computer visible on the network, but when I log in it requires a password that doesn't work?
This happens when the target computer doesn't have a user with the same username and password as yours. Solution: Either create an identical user, or in the password entry window, enter the target computer's username separated by a backslash (e.g., ComputerName\UserName) and its password. Alternatively, disable password protection in the advanced sharing settings.
Is it possible to connect laptops of different brands (Asus, HP, Lenovo)?
Yes, the laptop brand doesn't matter. What matters is the operating system installed. Windows 10 and Windows 11 work perfectly together, regardless of the hardware manufacturer.
What is the maximum transfer speed for Wi-Fi?
Speed depends on the Wi-Fi standard. For 2.4 GHz (Wi-Fi 4), actual speeds rarely exceed 4-6 MB/s. For 5 GHz (Wi-Fi 5/6), speeds can reach 40-80 MB/s and higher, comparable to fast flash drives.
