How to sync two laptops over Wi-Fi in Windows 10

Today's fast-paced work environment often requires instant access to data from multiple devices, making having two laptops on the same network the norm. Instead of using flash drives or cloud storage, which can be slow for large data volumes, a direct local network connection ensures maximum data transfer speeds. Synchronizing laptops Wirelessly connects documents, media files, and projects seamlessly, creating a unified digital ecosystem right on your desk.

operating system Windows 10 provides powerful built-in tools for organizing such interactions, although standard security settings sometimes hide these capabilities from inexperienced users. Understanding the principles of operation local network and proper access settings configuration make this process a simple procedure that takes just a few minutes. In this guide, we'll cover every setup step, from hardware verification to fine-tuning access rights.

For a successful connection, it is critical that both devices are on the same subnet and have correct IP addresses. Both laptops must be connected to the same router or Wi-Fi access point., as a direct computer-to-computer connection without a router requires a dedicated network and has its own nuances. Let's start by checking the basic settings to eliminate common errors at the start.

Preparing equipment and checking network status

The first step is to ensure that the physical connection is established and that the operating system sees the network as trusted. Often Windows 10 By default, it assigns new connections to the "Public Network" profile, which blocks the device's visibility to other users for security reasons. You need to change this status to "Private Network" to enable discovery.

Open the system settings by going to the menu Start → Settings → Network & Internet → StatusHere, under the name of your Wi-Fi connection, there should be a "Properties" button. Clicking it will reveal a network profile switch. If it says "Public," feel free to change it to "Private." This will enable the necessary discovery services.

Next, you should check whether the laptops can see each other at a basic level. Open the command prompt by entering cmd in the search, and use the command ipconfig to view the address. Write down the IPv4 address of the first laptop; you'll need it for a direct connection if automatic detection fails.

⚠️ Warning: If you use third-party antiviruses or firewalls, they may block the local connection even if Windows is configured correctly. Temporarily disable network protection or add an exception for the local subnet in your antivirus settings.

Setting up sharing options

After changing the network profile, you need to enable discovery features. Go to Control Panel → Network and Internet → Network and Sharing CenterOn the left, select "Change advanced sharing settings." This contains the key settings that allow laptops to "see" each other.

In the "Private (Current Profile)" section, you need to enable network discovery and file and printer sharing. It is also recommended to enable automatic configuration of network connections. Without these options enabled local area network will work, but the computers will remain invisible to each other in Explorer.

Pay special attention to the "All Networks" section. This is where you'll find the important "Password-protected sharing" setting. If you're in a trusted home environment, you can disable this setting to simplify access. However, if you have other devices on the network, it's best to leave protection enabled and use the same login credentials on both laptops.

Save your changes by clicking the "Save Changes" button at the bottom of the page. The system may require a restart of network services or the computer itself for the changes to take effect. After this, additional devices should begin to appear in Windows Explorer under "Network."

Creating a shared folder and assigning permissions

Now that the network is set up, you need to determine what data will be synced. Create a new folder on your drive or select an existing one. Right-click it and select "Properties," then go to the "Sharing" tab. Click "Advanced Setup."

In the window that opens, check the box "Share this folder." Below, click the "Permissions" button. By default, the "Everyone" group is set to read-only permissions. If you need full permissions, file synchronization with the ability to edit and delete from both laptops, select the "Everyone" group and check the "Full access" boxes.

Why is the folder not visible over the network?

If the folder is open but not visible, check Windows Services. Press Win+R and enter services.msc. Locate the "Function Discovery Resource Publishing" and "Discovery Provider Host" services. They should be running and set to "Automatic" as the startup type.

Don't forget to also go to the "Security" tab in the folder properties. The permissions in the "Access" and "Security" tabs must match. If the "Everyone" user or a specific user isn't listed in the security list, add them and grant them full permissions. This is a common error when network access is allowed, but the NTFS file system blocks write access.

Mapping a network drive for easy work

To make working with remote files as convenient as possible and as comfortable as working with a local drive, it's best to use the "Map Network Drive" feature. This will create a virtual shortcut in "My Computer" that's always at hand.

Open "This PC," right-click on an empty space, and select "Add new item to Network Places" or use the "Computer" → "Map network drive" menu. In the "Folder" field, enter the path to the resource in the following format: \\IP-address-of-the-second-laptop\Folder_Name or \\Computer_Name\Folder_Name.

Check "Reconnect at logon" to make the drive accessible immediately after Windows boots. If prompted for credentials, enter the username and password of the second laptop. Make sure the username and password are set to the same on both devices—this will prevent repeated authorization requests.

Using Nearby Sharing

In more modern builds Windows 10 (version 1803 and later) introduced the Nearby Share feature, which works similarly to AirDrop. It allows you to quickly share files and links via Wi-Fi Direct or Bluetooth without the complicated setup of shared folders. This is ideal for one-time document transfers.

To activate the feature, go to Settings → System → Shared FilesTurn on the "Nearby Sharing" toggle on both laptops. Select "Everyone around me" if the devices aren't in your Homegroup, or "My devices" if they're linked to the same Microsoft account.

To transfer a file, simply right-click the document, select the "Share" icon, and select the second laptop from the list of available devices. A notification will appear on the receiving end, which you must confirm. Transfer speed depends on the power of the Wi-Fi adapters and the distance between the devices.

Diagnostics and troubleshooting

Even with proper configuration, situations may arise where laptops cannot see each other. One common cause is a disabled NetBIOS service or blocked ports. Ensure that NetBIOS over TCP/IP support is enabled in the TCP/IP version 4 protocol properties.

It's also worth checking the Print Spooler and Windows Search services, which sometimes affect the visibility of computers in the network environment. Restarting these services services.msc often solves the problem of "lost" devices.

⚠️ Note: Windows settings interfaces may differ depending on the update version (21H2, 22H2, etc.). If you don't find the menu item, use the search in Settings or the command control to call the classic control panel.

If all else fails, try temporarily disabling Windows Firewall on both devices to test. If the connection reappears, the issue lies with the traffic filtering rules. In this case, it's easier to create a new inbound rule allowing traffic to the private network than to disable protection completely.

Questions and Answers (FAQ)

Is it possible to sync laptops without a router?

Yes, this is possible. You can create a temporary wireless network (Mobile Hotspot) on one laptop via the Wi-Fi settings, and connect the second laptop to this hotspot. After that, the shared folder setup process is the same.

Why am I asked for a password when accessing a folder, even though I didn't set one?

Windows 10 requires authorization by default. You'll need to either enter the username and password of the second laptop's user account or disable "Password-protected sharing" in the advanced settings (only for trusted networks).

What is the maximum data transfer speed for Wi-Fi?

Speed ​​depends on the Wi-Fi standard (n, ac, ax) and distance. Under ideal conditions, 5 GHz can achieve 30-50 MB/s of real data flow, which is comparable to the fast USB 2.0 but slower than USB 3.0.

Is it safe to leave a shared folder open?

If you're on a public network (like a cafe or airport), it's unsafe. Always use the "Public Network" profile in such places, which hides your PC. At home, using the "Private Network" profile is minimal, as long as you have a Windows password.
