Modern workflows often require the rapid exchange of large amounts of data between devices. Local area network Allows you to transfer files by the gigabyte, without depending on cloud storage speeds or searching for flash drives. Connecting one laptop to another via Wi-Fi in an environment Windows 10 — This is a standard procedure that can be solved using the operating system's built-in tools without installing third-party software.
The main challenge for users isn't the physical connection, but rather the correct configuration of access rights and device visibility. By default, the system seeks to protect users by hiding computers from prying eyes on public networks. data exchange was successful, you need to change the network profile and activate the corresponding services.
In this article, we'll walk you through a step-by-step process that will allow you to create a stable connection. We'll cover the nuances of setting up a firewall, choosing a network type, and sharing specific directories. This knowledge is essential for every PC owner to work effectively in a home or office environment.
Preparing equipment and checking drivers
Before you start setting up a logical connection, make sure that both devices are within a strong signal reception area. Wireless adapter The network card must be working properly, and the drivers must be updated to the latest version. If one of the laptops is using outdated network card software, the transfer speed may be critically low, or the connection may be constantly disconnected.
Check if the Wi-Fi module is enabled on both devices. Windows 10 This can be done through the notification center or with a switch on the case. It's also critical that both laptops are connected to the same wireless access point. Different frequencies (2.4 GHz and 5 GHz) on the same router usually don't cause problems, but connecting to different SSIDs (guest and main networks) will make the devices invisible to each other.
⚠️ Attention: If you're using a corporate network with Client Isolation enabled, you won't be able to connect laptops directly. This feature blocks traffic exchange between devices within the same Wi-Fi network for security reasons.
Make sure your antivirus software isn't blocking local connections. Sometimes third-party firewalls may interpret a connection attempt as an external attack. In this case, you'll need to temporarily disable protection or add an exception for it. local network in your antivirus settings.
Setting up network type and discovery options
The key to establishing a connection is the correct network profile. Windows divides connections into "Private" and "Public." For a laptop to be visible to another, both connections must be set to "Private." In a public profile, the system prevents device discovery, considering the environment potentially unsafe.
You can change the network type through the settings menu. Go to Start → Settings → Network & Internet → StatusClick on the properties of your Wi-Fi connection. In the window that opens, find the profile switch and set the value PrivateRepeat this operation on the second laptop.
After changing the profile, you need to enable network discovery. Open Control Panel → Network and Internet → Network and Sharing CenterOn the left, select "Change advanced sharing settings." Under "Private," enable "Turn on network discovery" and "Turn on file and printer sharing."
It's also recommended to enable the "Let Windows manage HomeGroup connections" option. This will simplify the authorization process when connecting. Be sure to save your changes by clicking the "Save changes" button at the bottom of the page. Without this step, all further settings will be ignored by the system.
Ensuring consistent workgroup names
For proper operation on a local network, all computers must be in the same workgroup. By default, Windows uses the name WORKGROUPHowever, if it was previously changed on one of the devices (for example, during a corporate build), visibility may disappear.
You can check and change the workgroup name through the system properties. Right-click the "This PC" icon and select "Properties." In the window that opens, find the "Advanced system settings" link or follow the path Control Panel → System → Advanced system settings.
☑️ Check network settings
In the System Properties window, go to the Computer Name tab. Here you will see the current workgroup name. If it differs on different devices, click the Change button and enter the default value. WORKGROUPAfter making changes, the system will require a reboot. Restart both laptops for the settings to apply.
The computer name itself also plays a role. It must be unique within the network and written in Latin characters without spaces or special characters. Using Cyrillic characters in the computer name can cause display errors in network environments on some versions of the SMB protocol.
Setting up shared access to folders and files
Once the devices have "seen" each other, you need to grant read or write permissions to specific data. You can share any folder on your hard drive. To do this, right-click on the selected directory and select "Properties."
Go to the "Access" tab and click the "Sharing" button. Select a user from the drop-down list. All (or Everyone) and add it. Set the permission level: "Read" will only allow viewing files, while "Read and Write" will allow editing and deleting the folder's contents from another laptop.
| Access level | User capabilities | Recommended use |
|---|---|---|
| Reading | Viewing and copying files | Transfer of documents, photos, videos |
| Reading and writing | Full control over files | Collaborating on projects |
| Owner | Full access control | Folder Administration |
There's also advanced settings available via the "Security" tab. Here, you can fine-tune permissions for specific users if you don't want to grant access to everyone. However, for a fast home network, the basic sharing settings are sufficient.
What to do if the folder won't open?
If the system asks for a password when you try to log in to the folder and you don't remember it, try entering the username and password for your Microsoft account or a local administrator account on the computer where the folder is located. Creating a new local user with a simple password on both computers often helps.
Connecting via the Nearby Sharing feature
In Windows 10 and 11, there is a more modern and simple way to transfer files that does not require complex network share setup. Function Exchange Nearby (Nearby Sharing) uses a combination of Bluetooth and Wi-Fi Direct to quickly transfer files between devices in close proximity.
To activate, open Start → Settings → System → Shared FilesTurn on the "Nearby Sharing" toggle. Make sure Bluetooth and Wi-Fi are enabled on both laptops. In the drop-down menu, select "Everyone around" or "My devices only," depending on your trust level.
The transfer process is intuitive: simply open the file, click "Share," and select the target laptop from the list. A notification will appear on the second device informing you that the file has been requested. This method is ideal for one-time transfers of photos or documents, but is less convenient for working with persistent network resources.
Solving common connection problems
Even with proper configuration, errors can still occur. One of the most common is "Windows cannot access..." Often, the problem lies in a disabled service. Support Publication Resource Discovery or Function Discovery Resource PublicationThey need to be run through the service. services.msc and set the startup type to "Automatic".
Another common scenario is requiring a password that is not accepted. This may be due to security policies. In the "Local Security Policy" (secpol.msc) you can disable the requirement for a complex password or allow blank passwords, although the latter is not recommended on open networks.
⚠️ Attention: The Windows 10 Settings interface is updated regularly. The location of some menu items may vary slightly between different builds (Home, Pro, Enterprise). If you can't find the item you need, use the search in System Settings.
If the laptops can't connect, try temporarily disabling your antivirus and Windows Firewall to test. If the connection is established, the issue lies with your traffic filtering rules. Don't forget to restore protection after configuring the settings.
Frequently Asked Questions (FAQ)
Is it possible to connect laptops without a router?
Yes, this is possible. You can create a virtual hotspot (Mobile Hotspot) on one laptop and connect the second one to it. Or you can use the Ad-Hoc mode, although this feature is hidden in Windows 10 and requires configuration via the command line.
What is the maximum transfer speed for Wi-Fi?
Speed depends on the Wi-Fi standard (n, ac, ax) and distance. Under ideal conditions, 30-50 MB/s of real-world file transfer speed can be achieved at 5 GHz, which is significantly faster than USB 2.0 but slower than a Gigabit cable.
Is it safe to keep sharing enabled all the time?
On a home network with a strong Wi-Fi password, yes. In public places (cafes, airports), it's strongly recommended not to leave your computer in the "Private" profile with detection enabled, as your files could become accessible to hackers.
Why did the "Access" tab disappear in the folder properties?
This may occur if the Connection Manager service is disabled or if the folder is located in a system directory with restricted administrator access. Try moving the folder to the root of the drive or to a user folder.
