Setting up a local network via a Wi-Fi router in Windows 10

Creating a unified information space within an apartment or small office is no longer the preserve of system administrators at large corporations. Today, integrating multiple devices into a single structure allows for instant document sharing, online gaming, or sharing a single printer for all users without the hassle of cables. Local area network Wireless connection provides the necessary mobility, eliminating the need to run Ethernet cables throughout the house.

operating system Windows 10 has built-in tools for organizing such interactions, but the default security settings often block detection of other devices immediately after installation. Understanding the principles of operation SMB protocols and firewall rules will help avoid typical mistakes when computers simply "don't see" each other in the list of network neighbors.

In this guide, we'll walk you through the router and operating system configuration process to ensure stable and secure data exchange. You'll learn how to properly configure access profiles and what settings need to be adjusted to ensure smooth network operation.

The first step is always to check the physical connection and the functionality of the equipment. Make sure that your Wi-Fi router The wireless network is turned on, the wireless network indicators are lit, and all computers to be grouped are successfully connected to the same access point. If the devices are in different frequency bands (2.4 GHz and 5 GHz) but on the same router, they will usually be able to see each other unless client isolation is enabled.

It's critical that all devices have up-to-date network adapter drivers installed. Outdated software can cause connection instability or even complete network invisibility, even if the internet is working properly.

⚠️ Note: Some providers use "Client Isolation" mode on the hardware side. If computers are connected but can't see each other, check your router settings—this feature may be blocking local traffic between Wi-Fi devices.

Modern encryption standards such as WPA3, can sometimes conflict with older network discovery protocols. If you're using a mix of new and very old hardware, try temporarily switching the security type to WPA2-PSK to conduct tests.

Basic network profile setup in Windows 10

operating system Windows 10 By default, it considers any new connection to be potentially dangerous and assigns it the "Public" profile. In this mode network discovery Disabled, making your computer invisible to other devices. To enable local file sharing, you must change this status to "Private."

To do this, click the Wi-Fi icon in the system tray and select "Properties" under your network name. In the settings window that opens, find the "Network Profile" section and switch the radio button from "Public" to "Private." This will automatically open the necessary ports in the firewall for local traffic.

After changing the profile, the system will apply the new firewall rules, allowing packets for discovery services to pass through. Without this step, further public access configuration is pointless, as requests will simply be ignored at the operating system level.

In corporate environments, profile changes may be controlled by group policies. If the toggle switch is unavailable or reverts to its default state, contact your system administrator, as manual configuration may be blocked.

Check that the IP addresses of all devices are on the same subnet. Typically, the router will issue addresses like this: 192.168.1.x or 192.168.0.xIf one computer has an address 192.168.1.5, and the other 192.168.0.5, they will not be able to interact without complex routing.

Configuring sharing settings

After setting up the network profile, you need to enable the relevant services in the Network and Sharing Center. Open Control Panel, go to Network and Sharing Center, and select Change advanced sharing settings. This is where you'll find the key switches that control your computer's visibility.

In the "Private (Current Profile)" section, enable network discovery and file and printer sharing. These settings allow your PC to broadcast its presence on the network and accept incoming connection requests to shared folders.

It's also worth paying attention to the "All Networks" section. Here you can set up password-protected sharing. If you disable this feature, anyone within Wi-Fi range will be able to access your files without entering a username and password. This is unsafe in public places, but convenient in a trusted home environment.

For a home network, it's often more convenient to use password-based accounts. This provides a basic level of security, preventing children or guests from accidentally accessing system files. When attempting to access the system, the system will prompt for the remote computer's user credentials.

If you decide to disable password protection, ensure your Wi-Fi is securely protected with a strong encryption key. Open file access combined with weak Wi-Fi security creates a serious vulnerability for your personal data.

⚠️ Note: Disabling password protection in the "All Networks" section makes your folders accessible to any device on the network. Use this option only if you completely trust all connected devices and are confident in the security of your Wi-Fi channel.

Advanced TCP/IP settings and computer name

Unique identification of each device on the network is critical for proper operation. Ensure that each computer has a unique name. To check and change this, right-click "This PC," select "Properties," and look for the "Rename this PC" button.

Names must be written in Latin letters and not contain spaces or special characters other than hyphens. Using Cyrillic characters or symbols such as "/", "\", or "*" may cause name resolution errors by the service. NetBIOS.

In some cases, automatically obtaining an IP address (DHCP) can cause the device's address to change after a router reboot. For desktop computers used for data storage, it is recommended to assign a static IP address.

To do this, go to Network and Internet Settings → Configure adapter settings, right-click on the wireless connection, select "Properties", then "Internet Protocol Version 4 (TCP/IPv4)". Enter the address manually, for example, 192.168.1.50, mask 255.255.255.0 and gateway (your router's address).

A static IP address simplifies connection because the path to resources won't change. You'll always know the exact address of the computer you need to connect to, which is convenient for creating network shortcuts.

Creating a shared folder and setting access rights

Now that the network is configured, you need to determine what data will be available to other users. Select the folder you want to share, right-click it, and go to "Properties." The "Access" tab is the one you're looking for.

Click the "Advanced Settings" button and check the "Share this folder" box. In the "Permissions" section below, you can fine-tune what users can do: read files only, or modify and delete them.

It's also important to check the "Security" tab in the folder's properties. Even if you've shared the folder, NTFS system permissions may be blocking access. Add the "Everyone" user (or Everyone) to the list and grant it the necessary rights (usually “Change” and “Read”).

Once the settings are applied, the folder will be accessible over the network. Other users will be able to see it by going to "Network" in File Explorer or by using the direct path. The path to the resource typically looks like this: \\ComputerName\Folder or \\192.168.1.50\Folder.

If the system requires a password when you try to log in, enter the username and password of the user account on the computer where the folder is located. This ensures control over who has access to the data.

Diagnosing visibility and connectivity issues

Even with proper configuration, situations may arise where computers cannot see each other. Often, the problem lies with Windows services that have stopped for some reason. Click Win + R, enter services.msc and find services related to SMB and detection.

The table below lists key services that must be running (status "Running") and have a startup type of "Automatic":

Another common cause is antivirus software. Third-party firewalls can block local connections, deeming them suspicious. Try temporarily disabling your antivirus to test this hypothesis.

It's also worth checking whether the SMB 1.0 protocol is enabled. In Windows 10, it's disabled by default due to vulnerabilities, but some older NAS devices or printers require it. You can enable it in "Turn Windows features on or off."

⚠️ Warning: The SMB 1.0 protocol contains critical vulnerabilities (e.g., WannaCry). Enable it only if absolutely necessary for older equipment, and ensure all devices on the network have the latest security updates.

Map a network drive for quick access

For the convenience of constantly working with shared files, you don't need to find a computer on the network every time. You can map a remote folder as a regular local drive (for example, drive Z:). This is done in File Explorer by clicking the "Map network drive" button.

Specify the drive letter and path to the folder. If you check "Restore at logon," the drive will be accessible immediately after Windows boots, without the need to log in again (provided the password is saved).

This approach simplifies the work of programs that cannot work with network paths. \\server\share, but require specifying a local path to the files. To the system, this will appear as a regular hard drive partition.

If the connection drops, check the power saving settings of your Wi-Fi adapter. In Device Manager, under the adapter properties, on the "Power Management" tab, uncheck the box next to "Allow the device to turn off to save power."
