Create a local network between computers via Wi-Fi in Windows 7 and 10

Creating a local network between two computers isn't just a way to transfer a few photos, but the foundation for organizing a convenient digital space in your home. When devices are connected via a Wi-Fi router, you can access shared folders, play online games, or even share a printer across multiple machines without the hassle of cables. Modern Microsoft operating systems, such as Windows 10 and her predecessor Windows 7, have built-in tools to implement this task, but their configuration often causes difficulties for users due to differences in interfaces and security policies.

Unlike a cable connection, a wireless network requires certain signal stability conditions and proper profile configuration. It is critical that both computers are on the same subnet and have the same IP address prefix assigned by the router. If this basic principle is ignored, data exchange will be impossible even if the network is visible. In this article, we'll cover the setup process in detail, highlighting nuances often overlooked in standard guides.

Before diving into complex setup, make sure your devices are connected to the same router. This is a given, but it's precisely where most beginners stumble when trying to connect a laptop to a home PC, one of which is connected to a mobile hotspot. Below, we'll walk you through a step-by-step process that will allow you to establish stable data exchange.

Basic equipment preparation and connection check

The first step is to physically and logically check the hardware's readiness. You need to make sure the Wi-Fi adapters on both computers are working properly, the drivers are installed correctly, and the devices can see the wireless network. Open the Network Control Panel and make sure the connection status is "Connected." If one of the devices shows Windows 7, and on the other Windows 10, there may be slight differences in the display of icons, but the essence remains the same.

It's important to understand that the network type plays a crucial role in your PC's visibility to other devices. When you first connect to a new Wi-Fi network, the system asks if you want to make your computer discoverable. To create a local network, you must select the "Private Network" profile (in older versions, this was called "Home Network"). If you select "Public Network," the system will block incoming connections for security reasons, and the computers will simply not see each other.

⚠️ Attention: Avoid connecting to public Wi-Fi networks in cafes or airports using the "Private Network" profile, as this makes your computer visible to other users on the network, potentially leading to data leaks. This setting is only secure in a trusted home environment.

Check if the Wi-Fi indicator on your laptop or system unit is lit. A lack of signal may indicate that the module is disabled by software. In some laptop models, especially those manufactured by HP or LenovoThere's a physical switch or key combination (e.g., Fn+F2) to enable the wireless module. Make sure Airplane Mode is disabled in the Network and Sharing Center.

Configuring IP addressing and workgroup settings

To successfully exchange data, computers must "understand" that they are on the same network segment. Typically, a router automatically assigns addresses via a protocol. DHCP, and manual intervention is not required. However, if automatic configuration fails, you may need to assign static IP addresses. This is especially relevant for older devices based on Windows 7, which sometimes lose connection with the DHCP server.

To check your current settings, open a command prompt and enter the command ipconfigFind the "IPv4 Address" line. The first three numbers of the address should be the same on both computers (e.g., 192.168.1.x); only the last number may differ. Also check the "Default Gateway"—this is your router's address; it should be identical on all devices.

A workgroup is a logical name that groups computers together. By default, Windows uses the name WORKGROUPIt's crucial that the workgroup name is spelled identically on both computers, respecting case. You can change it through the "System" menu in Control Panel or through the computer's properties.

• 📁 Make sure that the workgroup name on PC #1 and PC #2 is completely identical (WORKGROUP is recommended).
• 🔢 Check that the IP addresses are in the same subnet (e.g. 192.168.0.5 and 192.168.0.6).
• 📡 Make sure the default gateway (router address) is the same on all devices.

If you decide to enter IP addresses manually, do so carefully. An error in one digit of the subnet mask will result in computers not being able to see each other, although the internet will still work. For a home network, the mask is typically 255.255.255.0.

Enable network discovery and sharing

The most important step in the setup process is enabling discovery features. Without this, computers will ignore each other's requests, even when on the same network. Windows 10 And Windows 7 These settings are located in the "Network and Sharing Center" section, in the "Change advanced sharing settings" subsection.

Here you'll need to enable several key switches. First, enable "Network discovery" and "File and printer sharing." These options allow the computer to broadcast its presence on the network and accept incoming connection requests. It's also recommended to enable automatic configuration of network devices.

Setting up password-protected access deserves special attention. If you disable password protection, anyone who connects to your Wi-Fi will be able to access shared folders. If you enable it, the system will require the username and password of the remote computer's user account when attempting to access.

After making changes, be sure to click the "Save Changes" button. Sometimes the system may require a reboot for the new firewall settings to take effect. If you are using a third-party antivirus (e.g., Kaspersky or ESET), check its settings, as it may block local connections, considering them suspicious.

Advanced Firewall and Services Settings

Sometimes the default settings aren't enough, and the built-in Windows firewall continues to block the connection. This often happens when trying to connect disparate systems, for example, Windows 10 And Windows 7In this case, you need to manually check the incoming connection rules.

Open Windows Defender Firewall from the Control Panel and go to "Advanced Settings." We're interested in the rules for "File and Printer Sharing." Make sure these rules are enabled (green indicator) for the "Private" and "Guest" profiles. If a rule is blocked, double-click it and select "Allow the connection."

It's also worth checking that the necessary services are running. Click Win + R, enter services.msc and find services related to SSDP Discovery, Function Discovery Resource Publication And Computer BrowserThey must be running and running automatically. If the service is stopped, the network environment may appear empty.

⚠️ Attention: Service and firewall interfaces may vary slightly across Windows builds. If you don't find an exact name match, look for services with similar functionality related to Discovery and Network.

Creating a shared folder and setting access rights

Once the network is set up, you need to create the resource you'll be sharing. You can share any folder on your hard drive. To do this, right-click the folder, select "Properties," and go to the "Sharing" tab. Click "Advanced" and check "Share this folder."

Next, you need to configure permissions. Click the "Permissions" button. Here you can specify what users can do with files: read only, or also modify and delete. For a home network, the "Everyone" group is often selected and granted full permissions, but this reduces security. A more prudent approach is to add a specific user and grant them the necessary permissions.

It's important to remember to check the "Security" tab in the folder properties. Even if you've enabled access in the network settings, NTFS may restrict reading at the file system level. Add the "Everyone" user or group to the list and ensure they have "Read & Execute" and "Write" permissions.

Problem with access rights

If you get an "Access Denied" error when opening a folder, try adding the "Everyone" group to the permissions with full rights for diagnostic purposes only. If this helps, the issue lies with NTFS permissions, not network settings.

For convenience, you can use the "Home Group" function (relevant for Windows 7 and earlier versions Windows 10 (up to 1803). It simplifies the process by automatically creating a secure network with shared access to libraries. However, in modern versions of Windows 10 and 11, this feature has been deprecated in favor of the standard SMB protocol.

Common errors and how to fix them

Even with careful configuration, problems can still arise. One of the most common errors is "Windows cannot access \\ComputerName." This is often related to the SMBv1 protocol, which is disabled by default in newer versions of Windows due to vulnerabilities, but is required for communication with older versions. Windows 7 or NAS storages.

To enable support for older protocols, go to "Turn Windows features on or off" in Control Panel. Find "SMB 1.0/CIFS file sharing support" and enable both the client and server components. A reboot will be required afterward.

The DNS or NetBIOS cache is also often the problem. If computers can't see each other by name, try accessing them by IP address. In File Explorer, enter \\192.168.1.XXIf you can access the address by IP but not by name, there's a problem with name resolution, and you should check the DNS service or hosts file.

• 🔌 Check if your antivirus software is blocking local traffic (Public Network mode).
• 📛 Make sure that computer names on the network are unique and do not contain Cyrillic or special characters.
• 🔄 Restart the "Workstation" and "Server" services using the command prompt with administrator rights.

Don't forget that Wi-Fi adapter drivers also play a role. Outdated drivers on Windows 7 may not work correctly with modern WPA3 encryption standards used by new routers. In this case, it's worth temporarily downgrading your router's security level to WPA2-AES to test it.

Questions and Answers (FAQ)

Is it possible to create a network between computers without a router, directly via Wi-Fi?

Yes, this is possible using the Mobile Hotspot feature in Windows 10 or creating a computer-to-computer (Ad-Hoc) network in Windows 7. One computer distributes Wi-Fi, and the other connects to it as a regular access point.

Why doesn't Windows 10 see a Windows 7 computer in the network environment?

The issue is most likely related to the SMBv1 protocol, which is disabled by default in Windows 10 but is required for Windows 7. Also, check that the Function Discovery Resource Publishing service is enabled on both PCs.

Is it safe to disable password protection when accessing shared folders?

On a home network where you're confident in your neighbors and guests, this is acceptable for convenience. However, in an apartment building with poor Wi-Fi security, it's a risk. It's best to create a dedicated user with a simple password for network access.

How do I find out the IP address of another computer on the network?

Go to the desired computer, open the command prompt (cmd) and enter ipconfigYou're interested in the "IPv4 address" line. Alternatively, you can find this information in the client list in your router's web interface.

Does antivirus software interfere with the creation of a local network?

Yes, many third-party antivirus programs (Avast, Kaspersky, ESET) have their own firewalls that can block local connections, considering them potentially dangerous. Check your antivirus's network settings and select the "Home Network" profile.
