Creating a local network between two computers isn't just a technical whim, but a necessity for many users who need to quickly transfer large amounts of data, collaborate on projects, or play online games. Unlike using external drives or cloud storage, a direct connection ensures maximum transfer speeds, limited only by the bandwidth of your wireless adapter, and doesn't require an internet connection.
Many equipment owners are faced with the myth of the complexity of setup, however, the operating system Windows 10 provides built-in tools that make this process fairly transparent. You won't need to purchase additional equipment if both devices already have working modules. Wi-FiThe main thing is to correctly configure visibility parameters and data exchange protocols.
In this article, we'll cover every configuration step in detail, from checking drivers to setting up folder access rights. We'll cover both automatic network creation methods and manual IP address assignment, which is often required when specific restrictions exist on corporate or guest networks.
Preparing equipment and checking drivers
Before proceeding with software configuration, it's necessary to ensure that the network adapters are physically working properly. Users often try to configure a connection, forgetting that one of the laptops may have the wireless module disabled or the installed universal drivers don't support creating a local network.
Open the device manager and check the section Network adapters. Make sure your Wireless Adapter Displayed correctly, without yellow exclamation marks. If your device is marked with an error, download the latest software from the manufacturer's website, as standard Windows tools may not work reliably with some chip models. Realtek or Intel.
It's also important that both laptops are within range of a strong signal. The distance between devices when directly connected shouldn't exceed a few meters, especially if you plan to use the 5 GHz band, which has less penetration but offers higher speeds.
⚠️ Note: If you are using a corporate laptop, your organization's security policies may block the creation of new network profiles. In this case, contact your system administrator before making any changes.
Network profile setup and discovery
The key point in the operating system Windows 10 is a network profile type. By default, the system assigns new connections the "Public" profile, which hides your computer from other devices for security purposes. To pair laptops, you need to change this status.
Go to the Start menu and select "Settings," then open "Network & Internet." In the left column, select "Status" and click on the properties of your current connection. Here, you need to switch the profile from "Public" to "Private." This will allow the system to discover and be visible to other devices.
After changing your profile, you need to enable discovery. Go to "Control Panel" using the search bar, select "Network and Sharing Center," and go to "Change advanced sharing settings." In the "Private" section, enable "Turn on network discovery" and "Turn on file and printer sharing."
☑️ Check network settings
Creating a computer network: manual and automatic methods
There are two main ways to connect devices: using the Mobile Hotspot feature or creating a computer-to-computer (Ad-Hoc) network via the command line. The first method is more modern and user-friendly. Windows 10, the second one may be required on older devices or for specific tasks.
To create a hotspot on one of the laptops, go to "Settings" → "Network & Internet" → "Mobile Hotspot." Select the adapter that will be used for internet access (or simply create a hotspot), and enter a network name and password. On the second laptop, find the newly created network in the list of available Wi-Fi connections and sign in.
An alternative method involves using the command prompt with administrator rights. Enter the command netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=Password123, replacing the name and password with your own. Then start the network with the command netsh wlan start hostednetworkThis method gives you more control, but requires careful attention when entering syntax.
⚠️ Important: When using the command line, make sure your Wi-Fi adapter driver supports hosted network mode. Some newer adapters may ignore older netsh commands.
Setting up IP addresses for a stable connection
In some cases, automatically obtaining IP addresses via DHCP may not work correctly, especially if you're creating an isolated network without a router. In this situation, you'll need to manually assign static addresses so that laptops can see each other.
Open the Run window (Win+R), enter ncpa.cpl and press Enter. Find your wireless connection, right-click it, and select "Properties." Find "Internet Protocol Version 4 (TCP/IPv4)" in the list, select it, and click "Properties."
On the first laptop, set the IP address 192.168.1.1 and subnet mask 255.255.255.0On the second laptop, enter the address 192.168.1.2 with the same mask. The gateway and DNS can be left blank, as internet access through this network is not expected unless one of the laptops is sharing it.
| Parameter | Laptop 1 (Host) | Laptop 2 (Client) | Description |
|---|---|---|---|
| IP address | 192.168.1.1 | 192.168.1.2 | Unique device identifier |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | Determines the size of the network |
| Main gateway | (empty) | 192.168.1.1 | External network access address |
| DNS | (empty) | (empty) | Not required for local communication |
Organizing shared access to files and folders
After successfully connecting and configuring IP addresses, the most important step is making the data accessible. Simply creating a folder isn't enough—you need to explicitly tell the system that its contents can be accessed by other network users.
Create the folder you want to share, right-click it, and select "Properties." Go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box.
Next, you need to configure permissions. Click the "Permissions" button and ensure that the "Everyone" group or a specific user has "Read" permissions (if you only need to view files) or "Full Control" (if you also need to modify and delete files). Without this step, the second laptop will be able to see the folder but won't be able to access it.
There's also a "Security" tab in the folder's properties. Make sure the "Everyone" user with the appropriate permissions is added there. It often happens that the access settings allow access, but the security settings (NTFS) block it, causing an access error.
What should I do if the folder is visible but won't open?
Often, the problem stems from different user accounts. If the laptops have different logins and passwords, Windows may block access. Try creating identical user accounts with the same passwords on both computers or disabling password protection in the "Advanced sharing settings" section.
Mapping a network drive and transferring data
For easy access to remote files, it's best to map the shared folder as a network drive. This will allow you to work with files on the second laptop as if they were on your computer's hard drive, assigning them a drive letter (e.g., Z:).
Open "This PC," right-click on an empty space, and select "Add new item to Network Places" or use the "Map network drive" command in the menu. Enter the path to the folder in the following format: \\192.168.1.1\FolderName, using the IP address of the first laptop.
Check "Reconnect at logon" to automatically reconnect the drive after a reboot. Now you can copy files, play videos, or open documents directly, all while enjoying high speeds. local network, without the need to physically move data.
⚠️ Note: Copying speeds for large files may vary depending on network conditions. For critical data, always verify file integrity after transfer.
Diagnosis and solution of typical problems
Even with careful configuration, situations may arise where laptops stop communicating with each other. Most often, the problem lies with the Windows firewall or antivirus software, which may consider the new connection suspicious.
Try temporarily disabling the firewall or adding your private network connection to the exceptions list. Resetting network settings can also help: in the command prompt with administrator rights, run netsh winsock reset And netsh int ip reset, after which be sure to restart your computer.
If all else fails, check the Function Discovery Resource Publishing service. It should be running and running automatically. You can find it via services.mscThe absence of this service makes the computer invisible in the network environment.
Why does the ping work, but the folders are not visible?
This is a classic sign that the SMB protocol is blocked by a firewall. Check the inbound rules for File and Printer Sharing and ensure they are enabled for the private profile.
Is it possible to combine laptops if one of them runs Windows 7?
Yes, this is possible, but it will require additional configuration of the SMBv1 protocol, which is disabled by default in Windows 10 for security reasons. You will need to enable SMB 1.0/CIFS support in Windows components on your new laptop.
What is the maximum speed when connected via Wi-Fi?
Speed depends on the Wi-Fi standard (n, ac, ax) and environmental conditions. Under ideal conditions, 5 GHz can achieve 300-500 Mbps, which is significantly faster than USB 2.0, but slower than a direct Gigabit Ethernet connection.
Is internet required for a local network to function?
No, internet access is not required to transfer files between laptops. The local network operates independently. However, if one laptop has internet access, you can set up internet sharing for the second device.
Is it safe to leave sharing enabled?
On home networks with a strong Wi-Fi password, yes. However, in public places (cafes, airports), leaving the network profile set to "Private" and enabling public access is strongly discouraged, as this makes your files vulnerable to attack.
