Establishing local communication between devices on a home network often becomes necessary for quickly transferring large amounts of data or sharing resources. Instead of searching for a flash drive or uploading files to the cloud, limited by your internet connection speed, you can create a direct connection local connectionThis allows you to achieve the maximum transfer speed available from your wireless adapter and provides complete control over the process.
Modern operating systems such as Windows 10 And Windows 11, have built-in tools for this task, but they are often hidden behind several layers of security settings. Proper configuration requires attention to detail, especially when it comes to access control and device names. In this article, we'll walk through all the steps for creating a stable communication channel, eliminating common mistakes users encounter when first attempting setup.
To get started, make sure both computers are connected to the same wireless network. This is a fundamental requirement, without which further steps are pointless. If one laptop is using mobile internet and the other is connected via a router, they won't see each other in the network environment. Only when they're connected to the same network will they be able to see each other. network segment, devices can start exchanging data packets.
Equipment preparation and compatibility testing
Before starting the software setup, you need to ensure that the connection is physically possible. Both computers must be equipped with working Wi-Fi adapters that support the following standards. 802.11n, 802.11ac or newer. Older modules may be unstable or may not support the required encryption protocols, resulting in constant connection drops even with a perfect router signal.
It's important to ensure that the network type in your system is set to "Private." If Windows considers your home network to be "Public," it automatically blocks most discovery and sharing features for security reasons. You can switch profiles through the network settings, which is a critical step for a successful start.
It's also worth paying attention to operating system versions. While modern versions of Windows are highly compatible with each other, the connection between, for example, Windows 7 And Windows 11 This may require enabling support for older SMB protocols. Ideally, both computers should be running current OS builds to minimize driver issues.
- 📡 Make sure both Wi-Fi adapters are turned on and can see your home network.
- 🔒 Check that the same Wi-Fi network password is set on both PCs.
- 💻 Make sure computer names are unique and do not contain Cyrillic or special characters.
- ⚡ It is advisable that both devices are within the router's signal coverage area.
⚠️ Attention: If you're using a corporate or dorm network, administrators may have isolated clients from each other (Client Isolation). In this case, a direct connection between computers will be technically impossible, even if all settings are correct.
Basic Windows network settings setup
The first step in the configuration process is to align your network settings. Open the Network Control Panel and ensure that the "Make this computer discoverable" option is enabled for your current connection. This will allow your PC to send and receive broadcast packets announcing its presence.
Next, you need to configure sharing settings. In the "Advanced sharing settings" section, enable network discovery and file and printer sharing. For a home environment, it's also useful to enable HomeGroup management, although this feature has been deprecated in newer versions of Windows in favor of standard folder sharing.
Don't forget to check your IPv4 settings. In your wireless connection properties, ensure that IP addresses are assigned automatically (DHCP) if your router supports this feature. Static IP addresses can be assigned manually for convenience, but this requires careful planning to avoid address conflicts within the same subnet.
The next important aspect is the workgroup name. By default, Windows uses the name WORKGROUPIt must be identical on all computers you want to combine. If on one PC the group is called WORKGROUP, and on the other MSHOME, they will not see each other in the network environment, despite the working Wi-Fi.
☑️ Check network settings
Setting up shared access to folders and files
Once the network infrastructure is set up, you need to determine which resources will be accessible to the second computer. Simply enabling sharing isn't enough—you need to explicitly tell the system which folders can be opened for reading or writing. Select the folder you want to share, right-click it, and go to Properties.
In the "Access" tab, click "Advanced Settings" and check "Share this folder." Here you can also configure concurrent user limits and file caching. For a home network, these settings can be left at their default settings, but it's best to restrict access if the folder contains more than just media files.
Configuring security permissions is a critical step. Go to the "Security" tab and ensure that the "Users" group or a specific user has read and execute permissions. Without the appropriate permissions in the ACL (Access Control List), even with open network access, the system may prompt for a password or deny access.
If you plan to transfer files frequently, it makes sense to create a separate folder, for example, Share on disk C: or D:, and set access rights once. This will eliminate the need to dig into the properties of new files each time. You can also use the "Grant access to" feature in the context menu for quick sharing.
| Access type | Description of rights | Recommended use |
|---|---|---|
| Reading | The user can only open and copy files. | For media libraries, documents, archives |
| Change | The user can read, write and delete files | For work projects, general tasks |
| Full access | Full control, including changing access rights | For trusted administrators only |
| Special rights | Flexible customization of specific operations | For complex corporate scenarios |
⚠️ Attention: Be careful when granting full access to a folder on the system drive. A second user's mistake could result in the deletion of critical system files if permissions are inherited incorrectly.
Solving visibility and access issues
It often happens that all the settings are correct, but computers don't see each other in the "Network" list. This may be due to disabled services in Windows. First, check the status of the "Connect Now Discovery Resource Publishing" and "Computer Browser" services. They should be running and running automatically.
Another common cause of blocking is firewall settings. Third-party antivirus programs or the built-in Windows Defender can block incoming connections. Ensure that your firewall rules allow traffic for "File and Printer Sharing" on private networks.
If the problem persists, try resetting your network settings. In Windows 10 and 11, you can do this through the network settings and select "Reset network." This will reinstall your network adapters and reset all protocol settings to factory defaults, which often resolves mysterious connection issues.
It's also worth checking whether your router is blocking multicast traffic, which is used for device discovery. Some router models, especially those from ISPs, may have this feature disabled by default. Log in to the router's web interface at 192.168.0.1 or 192.168.1.1 will allow you to check these settings in the WLAN or Wireless Settings section.
What should I do if it asks for a password?
If the system prompts you for a username and password when you try to log in, use the credentials of the user on the computer whose folder you're accessing. Login: Username_on_Target_PC, Password: Password_for_this_PC. If the account doesn't have a password, create one or disable the password requirement in the advanced sharing settings (not recommended for security reasons).
Using the command line for diagnostics
For a more in-depth analysis of the connection, you can use command line tools. The command ipconfig This will allow you to find out your computer's current IP address. Write down the address of the second computer; you'll need it for a direct connection if automatic detection doesn't work.
You can check the availability of the second computer using the utility pingOpen Command Prompt as Administrator and type ping 192.168.x.x, substituting the IP address of the target device. If you receive responses, then the physical connection and basic routing are working correctly.
ping 192.168.1.55 -tThis command sends continuous packets to the specified address, which is useful for monitoring Wi-Fi channel stability over time. If you see packet loss or high response times, the problem may be radio interference or a weak signal, not a Windows setting.
To view all active network connections and ports, use the command netstatIt helps you determine whether your computer is listening for connection requests. Of particular interest is port 445 (SMB), which is used for file sharing in Windows.
Alternative methods of data transfer over Wi-Fi
If the standard Windows tools seem too complicated or unstable, there are alternative ways to set up a connection. One of the simplest methods is to create a temporary hotspot on one of the computers. In this case, one PC distributes the Wi-Fi, and the other connects to it, creating a direct connection without the need for a router.
You can also use third-party software for synchronization, such as Resilio Sync, Syncthing or ShareitThese programs create their own data transfer channels over the local network, often ignoring complex Windows permission settings and operating significantly faster than the built-in mechanism.
For occasional file transfers, technologies like Wi-Fi Direct or browser-based proxy apps are ideal. However, for regular office or home use, requiring access to shared databases or media libraries, properly setting up a native Windows network remains the most reliable and professional solution.
⚠️ Attention: Windows settings interfaces may vary slightly depending on the build version (21H2, 22H2, etc.) and the availability of updates. If you can't find the item, use the system settings search.
Frequently Asked Questions (FAQ)
Is it possible to connect computers if one is on Windows and the other is on macOS?
Yes, this is possible. On a Mac, you need to enable "File Sharing" in System Preferences and select the SMB protocol. When connecting from Windows, enter smb://Mac-IP-Address in the File Explorer address bar. You will need to enter your Mac username and password.
Why is the Wi-Fi transfer speed much lower than what is stated on the router?
Speed depends on the band (2.4 GHz is slower than 5 GHz), distance from the router, number of walls, and interference from neighboring networks. Actual speed is also always lower than theoretical due to the overhead of encryption and packet confirmation protocols.
Is it safe to keep folder sharing enabled all the time?
On a home network with a strong Wi-Fi password, the risks are minimal. However, in public places or if your Wi-Fi is accessible to strangers, it can be dangerous. It's recommended to disable network discovery when connecting to unfamiliar networks.
How to find out the IP address of a second computer?
On the second computer, press Win+R, enter cmd, then in the black window enter ipconfigFind the "IPv4 Address" line under your wireless adapter. This is the address you need.
