Connecting two laptops into a single local area network wirelessly is a challenge faced by many users who want to quickly exchange large amounts of data or collaborate. Windows 10 This process has been significantly simplified compared to previous versions, but still requires proper configuration of security and network discovery settings. If you want to create local network For gaming, file transfer, or remote control, you don't need to buy additional equipment like a router or switch.
Modern technologies make it possible to organize a connection of this type Ad-hoc or use the built-in internet sharing features, turning one of the laptops into a hotspot. This is especially relevant in situations where the external Wi-Fi router unavailable, damaged, or too far away. Properly configured network adapters ensure stable data transfer rates and protection from unauthorized external access.
In this guide, we'll cover every setup step in detail, from checking drivers to forwarding ports for specific tasks. You'll learn how to avoid common mistakes, why computers might not be able to see each other, and what firewall settings need to be changed. Following these instructions will help you get things running smoothly. wireless connection in a matter of minutes.
Checking compatibility and preparing equipment
Before you begin configuring the software, you need to ensure that both devices are technically ready. The key element here is Wi-Fi adapter, which must support "Master" mode or the creation of a virtual access point. Almost all modern laptops released after 2012 are equipped with modules that support these standards. 802.11n And 802.11ac, which ensures sufficient throughput.
It's also important to check the driver status. Outdated network card software may not contain the necessary features to create a local group or may be unstable. Open Device Manager and ensure there are no warning signs in the "Network Adapters" section and that your device model is correctly detected.
⚠️ Note: Some corporate laptops may have BIOS-level restrictions or IT security policies that prohibit the creation of unmanaged access points. In such cases, local network configuration may be blocked by the administrator.
For stable operation, it is recommended that both laptops be in line of sight or no more than 10-15 meters apart, unless obstructed by concrete walls. Also, ensure that the module is enabled on both devices. Wi-Fi and it is not in airplane mode.
Setting up your first laptop: creating a network
The process begins with configuring the device that will act as the host or server. You need to go to the network connections control panel. To do this, press the following key combination: Win + R and enter the command ncpa.cpl, then press Enter. In the window that opens, find your wireless adapter.
Next, you need to create a new connection. In Windows 10, you can do this through Settings → Network & Internet → Mobile Hotspot. Select the connection your laptop uses to access the internet (if available), or simply enable the hotspot feature. Set a network name (SSID) and a strong password using encryption. WPA2-Personal to protect the channel.
☑️ Preparing to create a network
An alternative, more advanced method for older versions or specific tasks is to use the command line. Launch Terminal as administrator and enter the command to create a virtual interface. This gives you more control over channel parameters and frequency.
netsh wlan set hostednetwork mode=allow ssid=MyLocalNet key=SecurePassword123After running the command, you need to start the network. Remember that the network name (SSID) and key must match on both devices when connecting manually. If you're using the built-in "Mobile Hotspot," the second laptop will see the network in the list of available connections as a regular Wi-Fi hotspot.
Connecting a second laptop to a local network
On the second device, the process is as simple as possible. Open the list of available wireless networks by clicking the Wi-Fi icon in the system tray near the clock. Find the network name you configured on the first laptop in the list. If the network isn't visible, click "Show hidden networks" or ensure the first laptop is indeed broadcasting a signal.
Enter the password you set earlier. System Windows 10 will ask you about the network type: select "Private." This is critical, as the "Public" profile will hide your computer from other devices for security purposes, blocking network discovery.
Once successfully connected, the system will assign both laptops IP addresses from the same subnet, usually in the range 192.168.137.x for mobile hotspots. You can check this by opening the command prompt and entering the command ipconfigPlease pay attention to the line "IPv4 address".
| Parameter | Laptop 1 (Host) | Laptop 2 (Client) |
|---|---|---|
| IP address | 192.168.137.1 | 192.168.137.2 (example) |
| Subnet mask | 255.255.255.0 | 255.255.255.0 |
| Main gateway | 192.168.137.1 | 192.168.137.1 |
| DNS | Auto or from provider | 192.168.137.1 |
If the IP addresses are in different subnets (for example, one starts with 192.168.0 and the other with 192.168.1), data exchange between them will be impossible without manually reconfiguring the TCP/IP protocol.
Setting up shared access to files and folders
The connection itself only establishes a physical and logical link between devices. To begin data transfer, you need to configure public access (Sharing). Open "Control Panel" → "Network and Sharing Center" → "Change advanced sharing settings".
In the "Private" (current) profile, enable the following options: "Turn on network discovery" and "Turn on file and printer sharing." It is also recommended to enable the "Let Windows manage HomeGroup connections" option, if available in your operating system.
⚠️ Warning: Enabling sharing on unsecured networks (such as cafes and airports) can expose your personal data to others. Use this feature only in trusted environments.
Now select the folder you want to share. Right-click it, select "Properties" → "Sharing" tab → "Sharing" button. Add the user "Everyone" and set the permissions to "Read and Write" if you want to be able to not only copy files but also modify them.
To access a folder on another computer, open File Explorer and enter in the address bar IP address of the first laptop (For example, \\192.168.137.1). The system may request the login and password of the user account of the first laptop.
What should you do if it asks for a password but you don’t remember it?
In this case, you can temporarily disable password protection in the advanced sharing settings by selecting "Turn off password-protected sharing." However, this reduces the security level of your local network.
Troubleshooting and common errors
Even with proper setup, situations may arise where laptops cannot see each other. One of the most common causes is a blocked connection. Windows Firewall or antivirus software. Check your incoming connection rules and ensure that file sharing is allowed on the private network.
Another common issue is different workgroup names. While this has become less of a concern in Windows 10, it's recommended that both computers have the same workgroup name specified in the "System" section; by default, this is WORKGROUPYou can change this in the system's advanced settings.
If you have a connection but no speed or it's extremely slow, check your Wi-Fi channel. In apartment buildings, the airwaves can be clogged with neighbors' signals. Use Wi-Fi analysis tools to find a clear channel, or switch your router/hotspot to 5 GHz.
- 🔌 Network reset: Windows settings have a "Network reset" feature that deletes all saved profiles and reinstalls adapter drivers.
- 🛡️ Antiviruses: Third-party antivirus programs (Kaspersky, ESET, Avast) often have their own built-in firewalls that can block local connections even when allowed in Windows.
- 💤 Power Saving: Check your adapter's power settings. Windows may disable the Wi-Fi module to save power, which interrupts the connection. Uncheck "Allow the computer to turn off this device" in Device Manager.
Keep in mind that network card drivers can also conflict after major Windows updates. If you experience persistent disconnects, try rolling back the driver or installing the version directly from the laptop manufacturer's website rather than through the update center.
Alternative connection methods and programs
If the standard Windows tools seem too complicated or unstable, there are third-party solutions. Programs like Hamachi or Radmin VPN They create a virtual local area network (VLAN) over your existing internet connection, routing traffic through their servers. This is ideal if your laptops are in different physical locations, but you want them to "think" they're nearby.
For simple file transfer without creating a full-fledged network environment, utilities like Feem or Send AnywhereThey operate over Wi-Fi, automatically detect devices on the network, and transfer files via TCP, bypassing complex Windows sharing settings.
⚠️ Warning: When using third-party VPN tunneling software, all your traffic may pass through the developer's servers. Do not transmit sensitive data through free, unencrypted versions of such services.
Also worth mentioning is the Nearby Sharing feature in Windows 10/11. It allows you to transfer files and links between nearby devices via Bluetooth and Wi-Fi Direct using your Microsoft account. It's the easiest way to transfer a one-time photo or document.
Is it possible to connect laptops via Bluetooth?
Technically, it's possible by creating a PAN network, but Bluetooth speeds are extremely low (up to 2-3 Mbps in reality). This is only suitable for transferring text documents, not photos, videos, or games.
Why can't the second laptop see the first one's folders, even though there's a network?
The problem is most likely with the network profile. If Windows considers the network "Public," it blocks discovery. Also, check that the "Function Discovery Resource Publishing" service is enabled in the Services section (services.msc).
How to find out the IP address of another laptop?
On the second laptop, open the command prompt (cmd) and type ipconfigYou're interested in the IPv4 address line. This is the address you need to enter into the first laptop's Explorer.
Is it safe to keep sharing enabled all the time?
No, not if you connect to public Wi-Fi networks. It's recommended to enable sharing only when you're at home, or use the "Hide PC" feature in your network settings when in public places.
Is it possible to play (LAN) games via a created hotspot?
Yes, absolutely. For online games (CS:GO, Minecraft, Dota), this connection method is even preferable, as the latency (ping) between laptops will be minimal, as the traffic doesn't go over the internet.
What should I do if I get the message "Windows can't connect to this network"?
Try "Forgetting" this network from the Wi-Fi list and reconnecting by entering the password. Resetting the TCP/IP stack with the command also helps. netsh int ip reset in the command line with administrator rights.
