How to create a home network using a WiFi router in Windows 10

Creating a local network between computers is a basic task for any user who wants to share files without using flash drives or cloud storage. In the operating system Windows 10 This process has become significantly more transparent, although it still retains a number of nuances related to security protocols. A properly configured infrastructure allows not only for data transfer but also for running online games, using a shared printer, or organizing a media library for a TV.

To get started, you'll need a working wireless router and at least two devices connected to it. Local area network (LAN) will only function if all participants are on the same subnet and have valid IP addresses. It doesn't matter whether you're connected via cable or Wi-Fi; the key is a single point of entry to the internet.

Before tackling complex router settings, make sure basic connectivity between devices is already established. Users often try to set up shared access without checking whether computers can see each other at the ICMP request level. This is the foundation without which further steps are pointless.

Checking basic connectivity and IP addressing

The first step in building any network structure is verifying the physical and logical connections. Your computer should automatically receive an IP address from the router unless static addressing is configured. Routers typically assign addresses in the range 192.168.0.1 or 192.168.1.1, but these values ​​may vary depending on the equipment manufacturer.

To find out your current address, open a command prompt by typing cmd in the Start menu and run the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter. Write down this number; you'll need it to configure other devices or to directly test for availability.

Now you need to make sure the devices are compatible. Open a command prompt on the second computer and enter the command ping [IP address of the first computer]If you see the response "Reply from...", it means the physical communication channel is working properly and data packets are passing through.

⚠️ Important: If you receive a "Timeout exceeded" message when trying to ping, the problem may be with your Windows Firewall settings, which by default blocks incoming requests from public networks.

Make sure your network profile in Windows 10 is set to "Private" and not "Public." A public profile limits device visibility to a minimum to protect data in cafes or airports, making it impossible to create a home network.

Setting up a network profile and discovery

The key point in organizing data exchange is changing the network profile. Windows 10 By default, it considers any new connection potentially dangerous and activates strict isolation mode. You must manually toggle this status to allow detection of other PCs.

To do this, go to System Settings from the Start menu and select "Network & Internet." In the list of active connections, find your Wi-Fi network and click on it. In the window that appears, select "Private." This will remove restrictions on incoming connections.

• 📡 Open "Network and Sharing Center" through the Control Panel.
• 🔒 Select "Change advanced sharing settings" from the left menu.
• 👁️ Enable the "Turn on network discovery" option for the current profile.
• 📂 Enable "Turn on file and printer sharing."

After applying the settings, the system may ask you to confirm the network ID change. Accept the changes for the new firewall rules to take effect. Without this step, computers will ignore requests to search for devices on the local network.

Organizing shared access to folders

Once the devices have recognized each other, you can begin setting up access to specific resources. You can share any folder on the drive, making it readable and writable by other computers on the network. This is especially convenient for organizing a family archive of photos or documents.

Right-click the folder you plan to use and select "Properties." Go to the "Sharing" tab and click "Sharing." In the window that opens, select "Everyone" (or a specific user if accounts are configured) and set the permission level.

It's important to distinguish between access levels: "Read" only allows viewing and copying files, while "Read and Write" grants permission to modify, delete, and create new files in this folder. For media servers, read-only permissions are usually sufficient.

There's also a more advanced method via the "Security" tab, where you can fine-tune access rights for specific Windows user groups. However, for a simple home network, the basic settings in the "Access" tab are sufficient.

Router Setup: Static IP and DHCP

While dynamic address assignment (DHCP) is convenient, for stable network resource operation (for example, if you're connecting a network printer or NAS), it's better to reserve IP addresses for specific devices. This can be done in two ways: manually on a PC or through the router settings.

Setting it up on the router is preferable, as it ensures that the address will not change even after a hardware reboot. Access the router's web interface (usually at 192.168.0.1) and find the section LAN or DHCP Server.

You will need the MAC address of your computer's network adapter. You can find it using the command ipconfig /all In the command line (the "Physical Address" line). Add this address to the Address Reservation list and bind the desired IP address to it.

Using static addresses simplifies connecting to resources, as you don't need to check the IP address assigned to the computer each time after a reboot. The file path will remain unchanged.

Port forwarding for remote access

If you plan to access your home network from the outside (via the internet), you'll need to set up port forwarding. This will allow external requests to reach a specific computer within your local network, bypassing the router's NAT protection.

Find the section in the router interface Port Forwarding, Virtual Server or NATHere you need to specify the internal IP address of your PC, the service port number (for example, 80 for web server or 21 for FTP) and protocol (TCP/UDP).

⚠️ Warning: Opening ports creates a potential security vulnerability. Never open ports for services with known vulnerabilities and use complex passwords for your accounts.

You can use online port scanning services to check if a port is open. If the service shows the port is closed, check your Windows Firewall settings—it may block incoming traffic even if the port is open on the router.

Modern routers often have a function UPnP, which allows applications to automatically open the necessary ports. However, for consistent and secure server operation, manual configuration is recommended.

Troubleshooting common visibility issues

Despite proper configuration, users often encounter a situation where computers cannot see each other in the network environment. One common cause is a disabled detection service or blocking by an antivirus program.

Check if the SSDP Discovery Function and Discovery Resource Publishing services are running. You can find them by entering services.msc in the run line. Make sure the startup type is set to "Automatic."

It is also worth checking the service's operation. SMB 1.0In new versions of Windows 10, this protocol is disabled by default due to vulnerabilities, but older network-attached storage (NAS) devices or printers may require it to function correctly.

How to enable SMB 1.0 safely?

Go to "Control Panel" -> "Programs and Features" -> "Turn Windows features on or off." Find "SMB 1.0/CIFS file sharing support" and enable the client-side feature. Use this only if other methods fail.

If the problem persists, try temporarily disabling your third-party antivirus. Often, built-in firewalls in antivirus packages have stricter rules for local networks than the standard Windows Defender.

Frequently Asked Questions (FAQ)

Why is my computer not visible on the network even though the internet is working?

Your network profile is likely set to "Public." In this mode, Windows hides your PC from other devices. Switch the profile to "Private" in your network settings and enable network discovery.

Is it possible to create a network between Windows 10 and older versions?

Yes, but compatibility with Windows 7 or XP may require enabling SMB v1 protocol support and changing password encryption settings in the registry or group policies.

Is it safe to open ports on a router?

This carries risks. Open only those ports that are truly necessary, and ensure the target computer has all security updates installed and uses strong passwords.

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

Use the command arp -a in the command line. It will display a table of IP addresses and physical MAC addresses of all devices your PC has recently communicated with.
