Modern users often need to quickly transfer large amounts of data between devices. Flash drives get lost, cloud storage takes time to load, and Bluetooth can't handle gigabytes of data. The solution is creating a local connection that allows for high-speed file sharing without the need for external drives.
There are several ways to connect two laptops wirelessly, each with its own unique features. You can use an existing home network via a router or set up a direct connection. computer-computer Without intermediaries. The choice of method depends on your infrastructure and speed requirements.
In this article, we'll cover all current setup methods, from classic to modern, applicable to Windows 10 and 11. We'll cover security nuances, sharing settings, and solutions to common problems users encounter when setting up a local network.
Equipment preparation and compatibility testing
Before you begin setup, you need to make sure both devices are ready to communicate. It's crucial that they are in good working order. Wi-Fi adapters on both laptops. Most modern models, such as HP Pavilion or Lenovo IdeaPad, have built-in modules, but older devices may require an external USB receiver.
Both laptops must be running compatible operating systems. Although Windows can operate on mixed networks, for seamless data transfer it is better to use the same OS versions, for example, two machines running Windows 10 or Windows 11This will simplify the setup of encryption protocols and shared folders.
⚠️ Attention: Make sure network discovery is enabled on both devices. If one of the laptops is in "Public Network" mode, the system may block incoming connections for security reasons.
It's also worth checking the battery charge or connecting the devices to a power source. The setup process and subsequent data transfer can consume significant power, especially if radio module at full power. It is not recommended to interrupt the process halfway due to battery discharge.
Method 1: Creating a local network via a router
The most stable and simple method is to use an existing infrastructure. If both laptops are connected to the same Wi-Fi router, they are already on the same local network. All you need to do is configure file and folder access permissions correctly.
First, you need to change the network profile to "Private." In Windows 10 and 11, this is done through the Network and Sharing Center. Go to Settings → Network and Internet → Wi-Fi and select your connection properties. Set the switch to the position Private networkto allow discovery by devices.
Next, you need to enable network discovery. Open the Control Panel, find "Network and Sharing Center," and go to "Change advanced sharing settings." Here, enable the following options:
- 📡 Enable network discovery
- 📂 Enable file and printer sharing
- 🔓 Allow management of HomeGroup connections
Once the settings are applied, the computers will be visible to each other in File Explorer. To access the files, create a folder, right-click it, and select Properties → Access → Advanced settings and check the box "Open public access".
Method 2: Direct Laptop-to-Laptop Connection (Ad-Hoc)
If you don't have a router handy, you can create a direct wireless connection between devices. This method is often called Ad-Hoc network. One laptop will act as an access point, distributing the signal, and the other will connect to it as a client.
On the first laptop (which will be the "server"), open a command prompt as administrator. Enter the command to create a virtual access point:
netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=Password123Here MyNetwork — the name of your network, and Password123 — the password for the connection. After creating the network, you need to start it with the command netsh wlan start hostednetworkNow the hotspot you created will appear in the list of available Wi-Fi networks on the second laptop.
☑️ Checking the direct connection
It's important to note that once such a network is created, an additional step may be required to transfer internet or access files. You need to go to Control Panel → Network Connections, find your main adapter (through which there is Internet, if there is one) or local network adapter, right-click Properties → Access and allow (shared access) for the created virtual adapter.
Setting up shared access and port forwarding
Simply connecting devices isn't enough—they need to be allowed to "see" each other's resources. In modern versions of Windows, security systems can even block local connections. You need to ensure that firewall rules are enabled for File and Printer Sharing.
Open "Windows Firewall" from the Control Panel. Select "Allow an app or feature through firewall." Find "File and Printer Sharing" in the list and ensure both private and public networks are checked.
| Parameter | Value for Server | Value for the Client |
|---|---|---|
| Network profile | Private | Private |
| Network discovery | Included | Included |
| File sharing | Included | Included |
| Password protection | Disabled (for simplicity) | Not required |
For easier access, you can disable the password requirement. Under "Advanced sharing settings," find "All networks" and select "Turn off password-protected sharing." This will allow you to connect to shared folders without entering your credentials, which is convenient in a trusted home environment.
Why isn't public access working?
The problem is often caused by the "Function Discovery Resource Publishing" service. Check in services.msc that it is running and set the startup type to "Automatic." Also, ensure that the DNS and SSDP Discovery services are running.
Transferring files and working with shared folders
Once successfully configured, you can move files as if they were on your computer's hard drive. Open File Explorer and enter the IP address of the second computer in the address bar (e.g., \\192.168.1.55) or its network name.
For ease of use, you can map the shared folder to a drive letter. Right-click "This PC" and select "Map Network Drive." Select an available drive letter and specify the path to the resource. The folder will now appear in "My Computer" as a local partition.
⚠️ Attention: Wi-Fi data transfer speeds vary greatly depending on the connection standard (802.11n, ac, ax) and the distance between devices. Using the 2.4 GHz band, speeds may be lower than using USB 3.0.
Use IP address instead of a computer name if the system is unable to locate a device by name for a long time. The IP address is a unique identifier on the local network and guarantees direct access to the desired node, bypassing name resolution services that sometimes fail.
Using third-party software for synchronization
If the built-in Windows tools seem too complicated or unstable, you can use specialized software. Programs like Resilio Sync, Syncthing or ShareIt for PCs create their own transmission channels, often ignoring the standard Windows settings.
These apps are especially useful when you need to constantly sync folders or transfer files between different operating systems (for example, Windows and macOS). They automatically detect devices on the network and encrypt traffic.
However, for a one-time transfer of a large file (a movie, a project archive), the built-in Windows mechanism or an FTP server will be more effective, since they do not require the installation of additional software and do not load the system with background processes.
Diagnosing and resolving connection problems
A common problem is when computers can see the network but not each other. First, check if they are on the same subnet. Open the command prompt and enter ipconfig. The addresses must match in the first three numbers (for example, 192.168.1.X), only the last digit may differ.
If you can ping but the folders won't open, try resetting your network settings. In Windows 10/11, you can do this via Settings → Network & Internet → Advanced network settings → Network resetThis will reinstall your network adapters and reset them to factory defaults.
- 🔍 Check your antivirus: it may be blocking local connections.
- 🔄 Reboot your router: sometimes resetting the DHCP cache helps.
- 📡 Wi-Fi drivers: Make sure they are updated to the latest version from the manufacturer's website.
It's also worth keeping in mind that interfaces and menu item names may vary slightly depending on the Windows version and system updates. If you can't find an option, use the settings search or refer to the documentation for your specific OS version.
Is it possible to connect laptops without a router if one of them does not have Wi-Fi?
Yes, but this requires additional equipment. A laptop without Wi-Fi must be connected to the router via an Ethernet cable, creating a bridge, or a USB Wi-Fi adapter can be used. A direct "one-cable" connection between laptops is only possible via Ethernet (twisted pair), using a special crossover cable or modern auto-detecting ports.
What is the maximum Wi-Fi transfer speed between laptops?
Speed depends on the standard: 802.11n (up to 150-300 Mbps), 802.11ac (up to 800 Mbps and higher), 802.11ax (Wi-Fi 6, up to 1.2 Gbps and higher). Actual file transfer speeds are typically 60-70% of the standard's theoretical speed due to protocol overhead.
Is it safe to leave sharing enabled all the time?
On a home network with a strong Wi-Fi password, yes. However, enabling public access in public places (cafes, airports) is strongly discouraged, as your files could become accessible to hackers on the same network.
Why does it ask for a login and password when connecting?
This is the "Password-protected sharing" security mechanism at work. To remove the prompt, you must either disable this feature in the sharing settings or create identical user accounts (login and password) on both computers.
