Creating a local network between multiple devices is a basic necessity for modern users, allowing them to share files, play online games, or access shared resources without the hassle of wires. When it comes to connecting a second computer via Wi-Fi, many people imagine a complex process involving cables, but modern wireless technologies allow for this. Wi-Fi This problem can be solved in minutes. All you need is a working router and basic knowledge of operating system settings.
Unlike a wired connection, a wireless network offers freedom of movement, but requires a more careful approach to security and signal stability. If both devices are within a strong reception area, you can achieve full data exchange at speeds close to those of a wired connection, especially when using the standard 802.11ac or axIn this article, we'll cover all the setup details, from hardware testing to fine-tuning access rights in Windows.
Before you begin configuring software, you need to make sure your physical hardware is ready for use. The key here is wireless router, which must be connected to the internet and broadcast a valid signal. If you plan to connect a desktop PC without a built-in Wi-Fi module, you will need to purchase an external USB adapter or a PCI expansion card.
⚠️ Important: Make sure the drivers for your Wi-Fi adapter are installed and updated to the latest version, as older versions of software often do not work correctly with network discovery features in newer Windows builds.
Checking the compatibility of communication standards is another important preparation step. If your router only supports the 2.4 GHz frequency and your computer is configured to operate exclusively on the 5 GHz band, the connection will fail. It's also worth checking that client isolation mode isn't enabled on your router.AP Isolation), which prevents devices within the network from seeing each other.
To get started, you'll need to complete a few simple steps to physically prepare your workspace. Place the second computer close to the router to eliminate interference during initial setup. Once connected, you can move the device to any point within signal coverage.
☑️ Equipment preparation
Basic network connection setup in Windows
The first step to creating a local network is to properly configure the network profile in the operating system. By default, Windows often assigns new connections the "Public Network" status, which prevents other computers from seeing the device for security reasons. You need to change this setting to "Private Network."
To do this, go to the Network and Network Control Panel or use the pop-up notification when connecting. Select "Yes" when asked "Do you want to allow other computers on this network to discover your PC?" This will enable the necessary discovery services and open ports for local traffic.
After changing the network profile, the system will automatically apply more trustworthy firewall rules. This means that standard file sharing protocols, such as SMB (Server Message Block), will be granted permission to operate. Without this step, the computers will be physically connected but software-isolated.
It's also important to ensure that both computers are on the same subnet. This means that the first three digits of their IP addresses must match. Routers typically automatically assign addresses from a range 192.168.0.x or 192.168.1.x through the service DHCP.
How to check your IP address
Open the Command Prompt (cmd) and enter ipconfig. Find the IPv4 address line. Make sure the first three numbers (e.g., 192.168.1) match on both computers, but the last number is different.
Setting up shared access to files and folders
Once the network connection is established, you need to configure sharing settings. This allows users on one computer to see folders and printers connected to another device. This can be done through the Network and Sharing Center section of the Control Panel.
In the "Advanced Sharing Settings" menu, enable network discovery and file and printer sharing for the current network profile (private). It's also recommended to disable password-protected access if you're in a trusted home environment to simplify login.
Now you need to select the folder you want to share with the second computer. Right-click it, select "Properties," and go to the "Sharing" tab. Click the "Sharing" button and add the user "Everyone," granting them read or read and write permissions.
| Access parameter | Description | Recommended value |
|---|---|---|
| Network discovery | PC visibility on the network | Included |
| File sharing | Read/write permission | Included |
| Password protection | Login requirement for entry | Disabled (for home) |
| Access to multimedia | Broadcast to TV and consoles | As desired |
Once the settings are applied, the folder will be accessible over the network. On the second computer, it will appear in the "Network" section of File Explorer. If you've configured everything correctly, you'll be able to copy files between devices at high speed, limited only by the processing power of your computer. Wi-Fi router.
Connecting via HomeGroup (for older versions) and Network Places
In Windows versions prior to 10, there was a convenient tool called "HomeGroup" that automated the setup process. In modern systems, Microsoft has abandoned this feature in favor of more flexible, but complex, manual settings. However, the principles of the network environment remain the same.
If automatic detection doesn't work, you can connect to the computer manually using its IP address or computer name. Open File Explorer and enter [my computer name] in the address bar. \\192.168.1.XX (where XX is the address of the second computer) and press Enter. The system will attempt to establish a direct connection.
A common issue is the lack of drivers or services responsible for older protocols. In some cases, enabling SMB 1.0 support may be necessary for proper operation in mixed networks (for example, Windows 7 and Windows 10), although this reduces the overall system security level.
⚠️ Warning: Enabling the SMB 1.0/CIFS protocol makes your network vulnerable to ransomware. Use this option only temporarily for file transfers and disable it immediately.
For easy access, we recommend creating a shortcut to the network folder on the desktop of the second computer. This will eliminate the need to search for the device in the network list each time. Simply drag the open network folder to the desktop or use the "Map Network Drive" feature.
Using built-in tools for remote control
Connecting a second computer via Wi-Fi is not only possible for file sharing but also for full remote control. Windows has a built-in tool called Remote Desktop (RDP) for this purpose. It allows you to see the second PC's screen and control it with your mouse and keyboard, as if you were sitting in front of it.
To enable this feature on the target computer (the one you'll be connecting to), go to "Settings" → "System" → "Remote Desktop" and toggle the switch to "On." Please note that Windows Home does not allow you to act as an RDP host, only as a client.
After enabling the feature on the second computer, enter the IP address or name of the first PC in the Remote Desktop Connection app. The system will prompt you for credentials: the username and password of the user logged in to the remote PC.
An alternative is the "Quick Assistance" feature built into Windows 10 and 11. It doesn't require complicated IP address configuration and works through your Microsoft account, making it convenient for providing technical support to family or friends. Simply launch the app and share the access code.
Alternative methods: creating a bridge and a hotspot
There are situations when a router is unavailable, but you need to connect two computers. In this case, one of the computers (usually the one with internet access or simply acting as a server) can provide Wi-Fi. The "Mobile Hotspot" feature in Windows allows you to turn your laptop into a hotspot.
Enable this feature in the network settings, set the network name and password. The second computer will connect to the created network as if it were a regular Wi-Fi router. After that, you can use the methods described above to set up folder sharing.
Another method is to create a bridged connection if one PC has Ethernet and the other only Wi-Fi, and you want to combine them into a single logical network. However, for simply connecting two devices via Wi-Fi, this method is overkill and is used in more complex home network configurations.
When using a laptop in hotspot mode, be mindful of power consumption. Wi-Fi hotspot mode drains the battery significantly faster, so it's recommended to connect the device to a power outlet during extended use.
Diagnosing problems and troubleshooting connection errors
Even with proper configuration, errors may still occur. The most common issue is "Windows cannot access \\ComputerName." This is often due to the Function Discovery Resource Publishing service not being running.
To check, open services (command services.msc) and find "Discovery Feature" and "Discovery Service Provider Host" in the list. Make sure they are running and their startup type is set to "Automatic." Restarting these services often resolves the visibility issue.
It's also worth checking your antivirus software. Third-party firewalls (such as those from ESET, Kaspersky, or Avast) may block your local network, treating it as public. In your antivirus settings, find the network profile and change it to "Trusted" or "Home."
⚠️ Please note: Router and operating system settings interfaces are constantly updated. The location of specific menu items may vary depending on the firmware version or Windows update. Always consult the manufacturer's latest documentation.
If all else fails, try temporarily disabling Windows Firewall on both computers to diagnose the issue. If the network works, the issue lies in the traffic filtering rules, and you'll need to create an exception for File and Printer Sharing.
Why can't the second computer see the first one on the network?
Most often, the problem lies in the network profile. If the network is marked as "Public" on at least one computer, Windows blocks discovery. Also, make sure the computer names (Workgroup) match; by default, it's "WORKGROUP."
How to increase file transfer speed over Wi-Fi?
Use the 5 GHz band, as it's less congested and offers higher throughput. Also, make sure you're using WPA2 or WPA3 encryption, not the outdated WEP or TKIP, which can reduce speed.
Is it possible to connect a macOS computer to a Windows network?
Yes, this is possible. On a Mac, you need to enable "File Sharing" in System Preferences and use the SMB protocol. When connecting from Windows to a Mac, you may be prompted to enter your Mac user credentials.
