Creating a unified digital space in an apartment or office is no longer the preserve of system administrators. Modern users are actively transferring large amounts of data between laptops, desktop PCs, and media players without the use of physical cables. Local area network Based on a wireless connection, you can instantly share documents, stream video on your TV, or use a shared printer.
In the operating system Windows 10 The process of organizing such interaction has been significantly simplified compared to its predecessors, but hidden security settings often block out-of-the-box connectivity. Understanding the principles of operation SMB protocols and proper firewall configuration are key factors for success.
This guide covers everything from checking basic adapter settings to resolving complex naming conflicts. You'll learn how to make folders accessible to other devices and understand why computers sometimes don't see each other in their neighbor list. A critical requirement is that all devices are on the same subnet, meaning they are connected to the same router or access point.
Basic preparation and verification of network profiles
Before starting a deep configuration, you need to make sure that the operating system correctly identifies the connection type. Windows 10 By default, it applies strict security rules to unfamiliar networks, hiding your device from detection. If your profile is set to "Public Network," the system will deny incoming connections, considering them a potential threat.
To change this setting, open the Start menu and go to "Settings," then select "Network & Internet." In the left column, find "Status" and click "Change connection properties." Here, toggle the switch to "Private." This will allow your computer to be visible to other devices within range of the Wi-Fi signal.
⚠️ Note: Switching your profile to "Private" opens ports for local data exchange. Make sure you're in a trusted home or office environment, not a Wi-Fi hotspot.
After changing the profile, it's recommended to restart the network adapter or completely reboot the device for the changes to take effect. Check the connection status: the "Properties" section should show "Connected, Secure." The system is now ready for more detailed sharing settings.
Enabling discovery and sharing features
The next step is to enable the services responsible for resource visibility. Even with the correct network profile, sharing functions can be disabled manually or by group policies. We need to enable network discovery and file sharing through the control panel.
Open the Control Panel, change the view to Large icons, and select Network and Sharing Center. On the left, click the link "Change advanced sharing settings." A list of profiles will appear. For the current profile (Private), select the following options:
- 🔍 Enable network discovery and automatic configuration of connected devices.
- 📂 Enable file and printer sharing.
- 🔐 Allow Windows to manage HomeGroup connections (if applicable).
Be sure to scroll down to the "All Networks" section. It's important to enable password-protected sharing here if you want to control who exactly has access to your data. If the network is completely trusted and protected from the outside world, you can temporarily disable protection to simplify connecting devices like Smart TVs or gaming consoles.
After making all changes, be sure to click the "Save Changes" button at the bottom of the page. Without this step, all settings will remain only in the interface's memory and will not be applied to the operating system's network stack.
Setting up shared folders and access rights
Simply enabling network discovery isn't enough—you need to tell the system exactly which resources you're willing to share. The permissions mechanism in Windows Two-level: there are NTFS file system permissions and share permissions. For proper operation, both levels must be configured.
Select the folder you plan to share, right-click it, and select "Properties." Go to the "Sharing" tab and click "Advanced." Check "Share this folder." Next, click "Permissions" and ensure that "Everyone" (or a specific user) has Read or Full Control permissions, depending on your needs.
| Permission type | Description of action | Recommended use |
|---|---|---|
| Full access | Reading, writing, modifying, and deleting files | Project working folders, shared storage |
| Change | Read, write, and delete, but without changing permissions | Folders for downloading files from other PCs |
| Reading | View and copy files only | Media libraries, document archives |
The second level of protection is found on the "Security" tab in the folder's properties. The user or group you're granting access to must be listed here. If the desired name isn't present, click "Edit" → "Add" and enter the user name or group "Everyone." Without matching permissions in the "Access" and "Security" tabs, the connection may be blocked with an "Access Denied" error.
☑️ Check access rights
Configuration of names and workgroups
For successful communication in a local network, all computers must be in the same working group and have unique names. If two devices have the same name, an addressing conflict will occur, and one will be unable to connect to the other's resources.
To check and change these settings, press the key combination Win + R, enter the command sysdm.cpl and press Enter. In the System Properties window that opens, on the Computer Name tab, you will see the current name and workgroup name. By default, Windows 10 uses the name WORKGROUP.
⚠️ Important: Changing the workgroup name requires a computer restart. Make sure all documents you are saving are closed before performing this operation.
When naming drives, use only Latin letters and numbers, avoiding spaces and special characters. This ensures compatibility with older devices and various operating systems that may be connected to your network, such as network-attached storage devices. NAS or media players.
How to change computer name without rebooting?
Technically, the changes only take effect after a reboot, as the computer name is registered in DNS and NetBIOS at system startup. Attempting to bypass this through the registry may result in unstable network services.
Troubleshooting SMB Visibility and Protocol Issues
One of the most common problems in modern versions of Windows is the lack of support for an outdated protocol, but necessary for some devices. SMB 1.0Microsoft disabled it by default due to security vulnerabilities, but many network printers and older NAS devices still use it for communication.
If your computer isn't visible on the network or can't connect to a network drive, check your Windows features. Open Control Panel, select Programs and Features, then Turn Windows features on or off. Find "SMB 1.0/CIFS File Sharing Support" in the list.
Expand the list and ensure the "SMB 1.0/CIFS Client" checkbox is selected. Enabling the server component is not recommended unless absolutely necessary, as it reduces the overall system security level. A reboot is required after enabling the component.
It's also worth checking the "Function Discovery Resource Publishing" service. Click Win + R, enter services.mscFind the service associated with discovery in the list and ensure it is running and the startup type is set to "Automatic." This is critical for the computer to appear in the "Network" section of File Explorer.
Diagnostics and Frequently Asked Questions
Even with careful setup, situations may arise where the connection is unstable or completely lost. Use the built-in diagnostic tool: right-click the network icon in the system tray and select "Diagnose." Windows will attempt to automatically reset the adapter and renew the IP address.
For more advanced diagnostics, use the command line. Launch Terminal as administrator and enter the command ping [IP-address-of-another-computer]If packets are being lost, the problem may be with the Wi-Fi signal or router settings that block communication between clients (AP Isolation).
⚠️ Note: Router interfaces and security settings may vary depending on the model and firmware version. Always consult the official documentation for your equipment if standard methods don't work.
Below are answers to the most frequently asked questions users have when setting up a wireless local area network.
Why can't computers see each other even though they have the same Wi-Fi?
Most often, the problem lies with the "Public" network profile on one of the devices or with ports being blocked by an antivirus program. Also, check that the workgroup name is the same on all PCs.
How do I remove the password prompt when accessing a shared folder?
In the Network and Sharing Center, under "All Networks," select "Turn off password-protected sharing." However, this reduces the security of your local network.
Is it possible to set up a network between Windows 10 and Windows 7?
Yes, this is possible. On Windows 10, you may need to enable SMB 1.0 support, as Windows 7 uses older file sharing protocols by default.
Does Wi-Fi speed affect large file transfers?
Absolutely. Local network speed is limited by the speed of the slowest device and the quality of the wireless signal. For files larger than 10 GB, an Ethernet cable or 5 GHz Wi-Fi is preferable.
