Modern users often need to quickly transfer large amounts of data between devices. Using cloud storage or external USB drives isn't always convenient, especially when both computers are in the same room. A local area network (LAN) built over a wireless connection allows for high-speed file sharing without the need for unnecessary wires.
In this guide, we'll walk you through setting up a local network between two laptops. We'll cover configuring Windows settings, correctly identifying the network type, and troubleshooting common issues with accessing shared folders. You'll be able to create a stable connection for work or gaming.
Establishing such a communication channel requires certain security settings to ensure your data remains protected from outside intrusion. It's important to understand the difference between a public and private network profile, as this determines access rules. Correct configuration will save you time in the future.
Preparing equipment and checking drivers
Before starting software configuration, you need to ensure that the wireless modules on both devices are working properly. Make sure the Wi-Fi adapters are enabled and functioning correctly. You can do this by checking the Device Manager or simply checking the list of available networks.
If one of your laptops uses an external USB swipe-up device, make sure it has the latest drivers installed. Outdated software can cause connection interruptions or slow data transfer speeds. We recommend visiting the hardware manufacturer's website.
⚠️ Note: If you're using a corporate Wi-Fi network with AP Isolation, connecting laptops directly won't work. In this case, you'll need to either access the router's settings or create a computer-to-computer network.
It's also worth checking whether the devices are within range of a strong signal. A weak signal will result in a drop in file transfer speed, making the process ineffective. If necessary, move the laptops closer to the router.
For stable operation, make sure that both devices have the latest versions installed. network card driversThis is a basic requirement for any network activity. Lack of updates can lead to security protocol conflicts.
Setting up network type and discovery
The key to setting up local networking is choosing the right network profile. Windows assigns new connections the "Public Network" status by default, which prevents your device from being visible to others. You need to change this setting.
Go to the network settings menu and select your current Wi-Fi connection. In the connection properties, find the "Network Profile" section and switch it to "Private." This will make your computer visible to other devices on the same network.
After changing your profile, you need to enable discovery features. Open Control Panel and find Network and Sharing Center. In the left menu, select Change sharing settings.
In the window that opens, expand the "Private (Current Profile)" tab. Here, you need to enable network discovery and file and printer sharing. Without these settings, the laptops won't be able to see each other, even when they're on the same network.
- 🔘 Enable network discovery
- 🔘 Enable file and printer sharing
- 🔘 Allow Windows to manage HomeGroup connections
Be sure to save your changes by clicking the corresponding button at the bottom of the window. The system is now ready to establish connections with trusted devices. A network service restart may be required for the settings to take effect.
Creating a network or connecting to a router
There are two main scenarios for establishing a connection: via an existing Wi-Fi router or by creating a direct network between laptops. The first option is the most common and easiest to implement. Both laptops connect to the same access point.
If you don't have a router or want to create an isolated environment, you can use the Mobile Hotspot feature or set up a computer-to-computer (Ad-hoc) network. In Windows 10 and 11, this is done through the Mobile Hotspot settings.
To create a direct network on one of the laptops, launch the command prompt as administrator. Enter the command to create a virtual access point. The second laptop should find this network in the list of available connections and connect to it by entering the password.
It is critical that both devices are on the same subnet, such as 192.168.1.x. If one laptop has an address of 192.168.0.5 and another has an address of 192.168.1.5, they won't be able to exchange data without complex routing. Routers typically assign addresses automatically via DHCP, which solves the problem.
Check the IP addresses of both devices. To do this, enter the following in the command line: ipconfigPay attention to the IPv4 address line. The first three numbers must match; only the last digit may differ.
Setting up shared access to folders
Once the network connection is established, you need to grant access to specific data. You can share any folder on the drive, making it readable or writable from another computer.
Right-click the folder you want to share and select "Properties." Go to the "Sharing" tab and click "Sharing." Select "Everyone" from the list and add them, setting their permission level.
☑️ Checking public access
You can also use advanced settings (Sharing). Click "Advanced Settings," check "Share," and click "Permissions." Here you can fine-tune who can edit files.
On the second laptop, open File Explorer and go to the "Network" section. If the settings are correct, you'll see the name of the first computer. Double-clicking it will open a list of shared folders. You may need the username and password for the first laptop's account to log in.
⚠️ Note: You may be asked to enter your credentials when connecting. The username and password must match those used to log into Windows on the remote computer. If you don't have a password, you may need to create one.
For convenience, you can create a shortcut to the network folder on your desktop. This will speed up access to files in the future. Simply drag the network folder to your desktop, and the system will prompt you to create a link.
Using special utilities and protocols
Standard Windows tools (like the SMB protocol) can sometimes be slow or require complex configuration. For faster file transfers, you can use specialized software that runs over your local network.
Programs like Resilio Sync, Send Anywhere or Feem They create their own data transfer channel. They often don't require setting up shared folders or access rights, operating on a P2P basis within the local network.
These utilities are especially useful if you need to transfer files between Windows and macOS or Linux. They bypass the limitations of the SMB protocol and are often faster than standard file transfers.
Why can standard SMB be slow?
The SMB protocol incurs overhead for access rights verification and encryption. On a local network without internet access, this can create delays. Specialized utilities use more lightweight protocols.
An FTP server is another option for organizing data exchange. You can deploy a lightweight FTP server on one laptop (for example, via FileZilla Server) and connect to it from another laptop via a browser or FTP client.
This method provides complete control over transferred data and allows the use of various clients. However, setting up FTP requires more technical knowledge than using ready-made applications.
Connection Method Comparison Table
To help you choose the right method, we've prepared a comparison table of the main methods for establishing connections between laptops.
| Method | Speed | Complexity | Security |
|---|---|---|---|
| Shared folder (SMB) | High | Average | High |
| Direct connection (Ad-hoc) | Average | High | High |
| Special utilities (Feem, etc.) | Very high | Low | Average |
| Bluetooth | Low | Low | Average |
As the table shows, a standard shared folder is best for ongoing work. For quick, one-time file transfers, specialized applications are more convenient.
Bluetooth should only be considered as a last resort if the Wi-Fi modules are faulty. Bluetooth transmission speeds are extremely slow by modern standards.
Solving typical problems
Even with proper configuration, errors can still occur. Users often encounter the message "Windows cannot access..." This is usually due to an antivirus or firewall blocking the connection.
Check your Windows Firewall settings. Make sure that "File and Printer Sharing" traffic is allowed for the private network. Sometimes, temporarily disabling your antivirus software for a check can help.
Another common issue is mismatched SMB protocol versions. There may be differences between older systems (Windows 7) and newer ones (Windows 10/11). On newer systems, SMBv1 support is disabled by default for security reasons.
⚠️ Warning: Do not enable SMBv1 support unless absolutely necessary. This protocol has vulnerabilities. It is better to configure SMBv2/v3 support on the client machine.
If the computers can't see each other, try a ping test. Open the command prompt and enter ping the IP address of the second laptopIf there is a response, then there is a physical connection, and the problem is in the access settings.
Also make sure that the Discovery Resource Publishing service is running. Click Win + R, enter services.msc and find this service in the list. It should be running.
Questions and Answers
Is it possible to connect laptops without a router?
Yes, it's possible. You can create a direct wireless connection (Ad-hoc) or use the Windows Mobile Hotspot feature to turn one laptop into a hotspot for the other.
Why does my laptop require a password to access a shared folder?
This is a standard Windows security measure. You'll need to enter the username and password of the user account on whose computer the folder is located. You can disable password protection in the advanced sharing settings, but this will reduce security.
What is the maximum transfer speed for Wi-Fi?
Speed depends on the Wi-Fi standard (n, ac, ax) and distance. In the 5 GHz band, actual speeds can reach 300-500 Mbps or higher, which is significantly faster than USB 2.0 but slower than Gigabit Ethernet.
Is it safe to open public access to a cafe?
No, always use the "Public Network" profile in public places. Enabling sharing on public networks makes your files visible to other users, which poses a data leak risk.
