Creating a local connection between two computers isn't just a way to transfer a few gigabytes of photos, but a fully-fledged tool for organizing collaboration or gaming. In the era of cloud storage, many forget that direct Wi-Fi channel provides data transfer speeds unavailable with most internet providers. For operating system users Windows 10 This process has become much more transparent, although it still requires attention to security settings.
You won't need additional cables or specialized software if both devices are within range of the same wireless network. System tools allow you to share files, printers, and even remotely control the screen of one laptop from another. The key is to correctly identify the current network profile and enable the necessary discovery services.
Before embarking on complex IP address manipulation, it's worth ensuring basic hardware compatibility. Modern routers automatically assign addresses, but sometimes the system requires a "ping" to recognize that another computer is nearby and can communicate with it. Let's walk through this process step by step, eliminating common rookie mistakes.
Checking network settings and access profile
The first and most critical step is to verify the status of your network. Operating system Windows 10 By default, it classifies new connections as "Public," which severely limits your device's visibility to others. You need to change this setting to "Private" to open ports for local communication.
To perform this procedure, open the Start menu and go to Settings by selecting the gear icon. Then follow the path Network and Internet → Status, where the name of your current Wi-Fi connection will be displayed. Click on it, and in the window that opens, select "Private" under the network profile.
This simple step unlocks discovery protocols, allowing the laptop to "broadcast" its presence. Without this step, any further sharing settings will be useless, as the firewall simply ignores incoming requests.
⚠️ Caution: Never switch your profile to "Private" if you're connected to public Wi-Fi at a cafe or airport. This will make your personal files vulnerable to attacks from other users on the same network.
After changing the profile, the system may require a network service restart, but most often the changes are applied immediately. Make sure both laptops complete this step, otherwise they simply won't "see" each other in the list of available devices.
Setting up sharing options
Once the network profile has been modified, specific services responsible for resource sharing must be enabled. Windows has a flexible permissions management system that blocks external connections by default for user security. We need to find a balance between security and accessibility.
Open Control Panel using the search bar and go to Network and Sharing Center. On the left, select Change advanced sharing settings. Here you'll see three profiles: Private, Guest, and All Networks. We're interested in the first one.
Enable the following options under "Private (Current Profile)":
- 📡 Enable network discovery
- 💾 Enable file and printer sharing
- 🔐 Allow Windows to manage HomeGroup connections
It's also worth paying attention to the "All Networks" section. Here you'll find the important "Password-protected sharing" toggle. If you're in a trusted home environment, you can disable it for easier access, but in the office or if you have children, it's best to leave it enabled.
⚠️ Note: Disabling password protection means that anyone who connects to your Wi-Fi will be able to access your shared folders without entering a username and password.
Save your changes by clicking the "Save Changes" button at the bottom of the page. The system will apply the new firewall rules, making your laptop visible to other devices on the same subnet.
Creating a shared folder for data exchange
Now that the network infrastructure is ready, you need to determine which files will be available for transfer. You can share any folder on the disk, but the easiest way is to use a standard directory or create a new one specifically for this purpose.
Create a folder, for example, on your desktop, name it Share or "Share." Right-click on it and select "Properties." Go to the "Sharing" tab and click "Sharing...." In the window that opens, select "Everyone" from the drop-down list and click "Add."
After adding a user, set the permission level. For simple file transfers, simply select "Read and Write" so the second laptop can not only retrieve files but also upload them to you. Click "Share" and then "Done."
This folder is now accessible over the network. To access it from another laptop, you'll need to know the host computer's name or IP address. You can find the name by opening System Properties (right-click "This PC" → "Properties"), and we'll look at the IP address in the next section.
Finding an IP address and connecting to a network
For a stable connection, it's best to use a static IP address or at least know the current dynamic IP address of the target laptop. This will prevent problems when computers lose connection after a router reboot.
On the laptop where the folder is shared, open the command prompt. Click Win + R, enter cmd and press Enter. In the black window, enter the command:
ipconfigFind the line "IPv4 address". It usually looks like this: 192.168.1.X or 192.168.0.XWrite down these numbers. Now go to the second laptop. Open "This PC" and in the address bar at the top, enter two backslashes and the IP address of the first laptop, like this: \\192.168.1.55.
If everything is done correctly, you will see the folder open. For convenience, you can right-click the folder and select "Map network drive" to make it appear as a separate drive (e.g., Z:) in "My Computer."
If the system prompts you for credentials, enter the username and password for the user account on the first laptop. These credentials are verified during authorization.
Organizing a local network using Close Interaction
Windows 10 offers a more modern and simple way to transfer files between nearby laptops, eliminating the need to set up complex network connections. The feature is called Near Share and uses a combination of Wi-Fi and Bluetooth.
To enable it, go to Settings → System → General Notifications. Make sure the "Use Proximity" slider is turned on on both devices. Also, make sure Bluetooth is enabled.
Now the transfer process looks elementary:
- 📄 Select the file you want to send.
- 🖱️ Right-click and select "Share".
- 📡 From the list of available devices, select the name of the second laptop.
- ✅ A notification about an incoming file will appear on the second laptop, which you will need to confirm.
This method is ideal for quickly transferring documents or a few photos, but for transferring gigabytes of data it may be less stable than a direct network connection via SMB.
Why isn't Close Interaction working?
This feature may not work if one of the devices has power-saving modes that disable Bluetooth, or if the network card drivers don't support Wi-Fi Direct. Both devices must also be signed in with the same Microsoft account or be in the same homegroup.
Solving common connection problems
Even if you follow all the instructions, sometimes situations arise where laptops stubbornly refuse to communicate with each other. Most often, the problem lies with third-party antivirus software or Windows services that were disabled for system optimization.
Check the status of the following services. Click Win + R, enter services.msc and find in the list:
- 💻 Function Discovery Provider Host
- 🔍 Publishing a feature discovery resource
- 🖥️ Computer (Computer Browser)
Make sure the startup type is set to "Automatic" and they are running. If the service is stopped, click "Start."
It's also worth checking your firewall settings. Sometimes antivirus software (such as Kaspersky or ESET) blocks a local network, considering it "Public." Go to your antivirus settings and find the "Network" or "Firewall" section. There, you should be able to allow data exchange on trusted networks.
| Problem | Possible cause | Solution |
|---|---|---|
| Password prompt upon login | Password protection is enabled | Disable it in the Network and Sharing Center or enter your account password. |
| Error 0x80070035 | The network path was not found. | Check PC name, enable SMB 1.0 service (rare) |
| The folder is visible, but access is denied. | NTFS permission error | Add a user in the Security tab of the folder properties |
| The laptops don't see each other. | Different subnets or isolation | Check that both are connected to the same router. |
⚠️ Note: Windows 10 settings interfaces may differ depending on the build version (21H2, 22H2, etc.). If you can't find a setting, use the search within the Settings menu.
Frequently Asked Questions (FAQ)
Is it possible to connect laptops via Wi-Fi without a router?
Yes, it's possible. You can create a direct computer-to-computer connection (Ad-Hoc network) or use the Mobile Hotspot feature in Windows 10, turning one laptop into a hotspot that the other can connect to.
What is the maximum file transfer speed over Wi-Fi?
Speed depends on the Wi-Fi standard (n, ac, ax) and distance. In the 5 GHz band, the standard Wi-Fi 5 (AC) The actual speed can reach 40-50 MB/s, which is comparable to fast USB 2.0, but significantly slower than wired Gigabit Ethernet.
Do I need the same password for my account on both laptops?
No, passwords can be different. The main thing is that when connecting, you enter the valid credentials (login and password) of the user whose resources you are trying to access on the remote computer.
Is it safe to keep sharing enabled all the time?
If you're using the "Private" network profile and are behind a home router with NAT enabled, the risks are minimal. However, if you frequently connect to public Wi-Fi, it's best to create separate shared folders and delete them when no longer needed.
