A modern home office or media system rarely does without the ability to exchange data between devices. Local area network allows you to transfer files, use a shared printer, or play media on your TV without the hassle of wires. In the era of Windows 10 The setup process has become simpler, but still retains a number of nuances that often confuse users.
The main advantage of a wireless connection is that there is no need to run Ethernet cables throughout the entire apartment. However, the speed and stability of the connection directly depend on the quality router and the correct configuration of operating system software parameters. If you want to create a fully functional collaborative environment, you need to configure access profiles correctly.
In this article, we'll detail a step-by-step guide to avoiding common device visibility issues. You'll learn how to change your network profile, enable necessary services, and grant file access. Without changing the network profile to "Private", detection of other computers in the Wi-Fi zone will be blocked by the security system by default.
Basic hardware and driver requirements
Before proceeding with software configuration, you must ensure that the hardware is in good physical condition. All computers planned for grouping must be connected to the same network. wireless routerDifferent frequency bands (2.4 GHz and 5 GHz) are usually not an obstacle if the router is properly configured to combine clients.
Keeping your wireless adapter drivers up-to-date is critical. Outdated software can cause connection drops or incorrect discovery protocols. You can check your driver version via device Manager, having found the section Network adapters.
- 📶 Make sure all devices are within range of the router's signal.
- 💾 Update your Wi-Fi adapter drivers to the latest version from your laptop or motherboard manufacturer's website.
- 🔒 Make sure all PCs use the same encryption type (usually WPA2-Personal).
It's worth noting that some corporate security policies or antivirus packages may block local connections. In such cases, temporarily disabling the third-party firewall is necessary for diagnostic purposes.
Setting up a network profile and discovery
System Windows 10 By default, it assigns the "Public" profile to new Wi-Fi connections. This is the most secure mode, hiding your computer from other devices on the network but also blocking local network access. To enable file sharing, you need to change the profile.
Go to the menu Start → Settings → Network & Internet → Wi-FiClick on the name of your current wireless network. In the window that opens, under the "Network Profile" heading, select the option PrivateThis action will allow the computer to become visible to other trusted devices.
⚠️ Attention: Don't select the "Private" profile if you're connected to public Wi-Fi at a cafe, hotel, or airport. This will make your files vulnerable to attacks from other users of the same hotspot.
After changing the profile, you need to activate the detection features. Open Control Panel → Network and Internet → Network and Sharing CenterOn the left, select "Change advanced sharing settings." Expand the "Private (current profile)" section and enable the following options:
- 🔍 Enable network discovery.
- 📂 Enable file and printer sharing.
- 🏠 Allow Windows to manage HomeGroup connections.
Save your changes by clicking the "Save Changes" button. Without this step, the computers simply won't be able to see each other, even if they're on the same Wi-Fi network.
Creating a shared folder and setting access rights
Once the network infrastructure is configured, you need to determine which resources will be accessible to other users. The easiest way to do this is to create a new folder for shared files to avoid getting lost in the system directories.
Create a folder in a convenient location (for example, on the D: drive or in the root of the C: drive), name it, for example, ShareRight-click on it and select "Properties." Go to the tab Access and click the "Advanced settings" button.
In the window that opens, check the box next to "Share this folder." Below, click "Permissions." Here you can fine-tune permissions for the "Everyone" group or specific users:
| Permission type | Full access | Change | Reading |
|---|---|---|---|
| Allow | ✅ | ✅ | ✅ |
| Ban | ❌ | ❌ | ❌ |
For a home network, checking the "Full Control" box for the "Everyone" group is usually sufficient if you trust everyone connected to your Wi-Fi. However, for greater security, it's best to leave the "Read" and "Modify" permissions only.
Connecting to a network resource from another computer
Now let's move on to the device from which you plan to access the files. Open File Explorer and find the "Network" section in the left navigation panel. If your settings are correct, you should see the name of the computer on which the shared folder is located.
When you first connect, the system may ask for credentials. Enter your account username and password. Windows the computer where the folder is located. If you're using a local account without a password, access may be denied by security policies.
For ease of use, you can map the network folder as a separate drive. To do this, right-click "This PC" in File Explorer and select "Map network drive." Specify the drive letter and path to the resource in the following format: \\ComputerName\FolderName.
- 💻 Open "This PC" in File Explorer.
- 🔗 Click "Map network drive" on the top bar.
- 📁 Enter the path or find the computer in the list.
- ✅ Check the box "Reconnect at logon."
If the computer doesn't appear in the list, try entering its IP address directly into the address bar of File Explorer. You can find the IP address on the target computer using the command ipconfig in the command line.
Troubleshooting common connection errors
Even with proper configuration, users often encounter access errors. One of the most common is "Windows cannot access...." Often, the problem lies in a disabled discovery service.
Click Win + R, enter services.msc and find the "Resource Discovery" service. Make sure it's running and the startup type is set to "Automatic." Also check the "Discovery Resource Publishing" service.
⚠️ Attention: Third-party antivirus programs (Kaspersky, ESET, Avast) often have their own built-in firewalls that block local networks regardless of Windows settings. Check your antivirus's Firewall settings.
Another possible cause is a disabled SMB 1.0 protocol, although it's often not required in modern versions of Windows 10 if all computers are up to date. However, in mixed networks with older NAS or Windows 7, enabling it may be necessary.
How to enable SMB 1.0?
Go to Control Panel → Programs and Features → Turn Windows features on or off. Find "SMB 1.0/CIFS file sharing support" in the list and check the box. A reboot is required.
Optimizing Wi-Fi data transfer speed
A wireless network is always slower than a wired one, and this becomes noticeable when transferring large files. For maximum speed, ensure both devices are operating in the 5 GHz band if your router is dual-band.
It also makes sense to disable power saving for your Wi-Fi adapter. In Device Manager, find your wireless adapter, go to Properties → Power Management, and uncheck "Allow the computer to turn off this device to save power."
If the transfer rate drops to zero or the connection frequently drops, check the channel load. Neighbors using overloaded channels can significantly reduce the local network's throughput.
☑️ Wi-Fi Speed Diagnostics
Local data exchange security
By opening access to files, you potentially expand your attack surface. Never use complex passwords for simple tasks, but don't leave access completely open if you have guests on your network.
It's recommended to regularly check the list of connected devices on your router. If you notice an unknown device, change your Wi-Fi network password immediately.
Frequently Asked Questions (FAQ)
Why can't computers see each other even though they have the same Wi-Fi?
Most likely, the network profile on one of the computers is set to "Public." Also, check that Resource Discovery is enabled and that your antivirus isn't blocking the connection.
Is it possible to connect to a local network via a guest Wi-Fi router?
Usually not. The "Guest Network" mode on routers is specifically designed to isolate clients from each other for security purposes. Devices in the guest zone only see the internet, not local resources.
How to find out the IP address of a computer for direct connection?
Open command prompt (cmd), enter the command ipconfig and find the line "IPv4 Address" in the section of your wireless adapter.
Does local networking work between Windows 10 and macOS?
Yes, it works. However, on a Mac, you may need to manually enter the address in the format smb://Windows IP address via Finder → Connect to server.
