The modern digital ecosystem of an apartment or office rarely exists without the exchange of data between devices. Local area network It remains the fastest way to transfer large files, play games, or share printers without using external cloud storage. Windows 10 offers flexible tools for configuring such connections, but default security settings often hide computers from other network users.
The basis of the entire infrastructure in this case is Wi-Fi router, which functions as a router and DHCP server. It assigns IP addresses and facilitates communication between wireless clients and wired devices. Properly configured hardware and operating system allow you to transform disparate devices into a single computing system with shared access to resources.
In this article, we'll cover not only the basic connection steps but also delve into the intricacies of discovery protocols and security groups. You'll learn why your laptop may not be visible in your network and how to fix folder access errors. The key is to set all devices to the same network type, "Private," since Windows blocks incoming connections by default in the "Public" profile.
Preparing equipment and checking connections
Before proceeding with software settings, you need to ensure that the devices are physically accessible to each other. All computers, laptops, and media players must be connected to the same router. This can be either a wireless connection or a wireless connection. Wi-Fi, and wired through LAN cableA mixed connection type (partly cable, partly over the air) is also acceptable and works correctly when configured correctly.
Make sure the network adapter on each device is enabled and functioning correctly. There shouldn't be any yellow exclamation marks next to the network controllers in Device Manager. If you're using complex corporate networks with client isolation enabled on the access point, direct connections between devices will be impossible without changing the router's settings.
- 📡 Make sure all devices are on the same subnet (usually 192.168.0.x or 192.168.1.x).
- 🔌 Check that the LAN/WLAN indicators on the router are lit when connecting cables or devices.
- 🔐 Make sure your Wi-Fi uses a single encryption method (WPA2/WPA3 recommended).
A common mistake is attempting to combine devices connected to different router frequency bands if they are configured for isolation or different VLANs. In home environments, routers typically combine the 2.4 GHz and 5 GHz bands into a single logical network, but in a corporate environment, this may not be the case.
Setting up the network type and discovery profile
The most important step in Windows 10 is choosing the right network profile. The operating system divides networks into "Public" and "Private." In the public profile, the system minimizes the computer's visibility to protect against hackers in cafes or airports. For a home network necessary Switch your profile to "Private".
To do this, open the network settings by clicking the Wi-Fi or monitor icon in the system tray. Select "Properties" for the active connection. In the window that opens, find the "Network Profile" section and set the switch to "Private." Windows will then allow incoming connections and enable discovery.
⚠️ Note: Changing your network profile to "Private" makes your computer visible to other devices on the network. Make sure you trust all users connected to your Wi-Fi router.
Next, you should check your sharing settings. Go to Control Panel → Network and Sharing Center → Change advanced sharing settings. Here, you need to enable network discovery and file and printer sharing specifically for the current profile (Private network).
☑️ Check visibility settings
It's also worth paying attention to the "Connect Discovery Resource Publishing" service. If it's stopped, the computer may not appear in the list of network devices even with the correct profile settings. You can start it using the command services.msc, finding the appropriate service in the list and selecting the startup type “Automatic”.
Configuring shared access to folders and printers
Once the network has "discovered" the devices, you need to grant access to specific resources. Simply enabling discovery isn't enough—you must explicitly specify which folders will be shared. Select the desired directory, right-click, and select "Properties." The "Access" tab is the one you're interested in.
Click the "Advanced Settings" button and check the "Share this folder" box. You can also configure permissions here: allow read, modify, or full access for specific users or the "Everyone" group. Using the "Everyone" group simplifies the connection, but reduces security.
| Permission type | Description of action | Recommended use |
|---|---|---|
| Reading | The user can only open and copy files. | Media libraries, document archives |
| Change | Reading, writing, and deleting files is allowed. | Working folders for joint projects |
| Full access | Full control, including changing access rights | For network administrator only |
| Special rights | Flexible customization of specific operations | For experienced users |
The procedure is similar for printers. Go to "Devices and Printers," select the desired device, right-click, and select "Printer properties." On the "Sharing" tab, check "Share this printer." Now any computer on the network can install the driver and print to this device.
NTFS permissions issue
If you encounter an access error when opening a folder, check the "Security" tab in the folder's properties. There should be read/write permissions for the "Everyone" user or a specific guest account, even if "Access" says "Everyone" is open.
Keep in mind that when attempting to connect from another computer, the system may prompt you for a username and password. These are the credentials of the computer where the folder is located. If you prefer to avoid entering a password, you can disable password protection in the advanced sharing settings, but this is only permissible in a trusted home environment.
Working with IP addresses and static routing
In a standard situation, the router itself distributes IP addresses via the protocol DHCPHowever, for stable network operation, especially if you plan to frequently access files via IP or configure port forwarding, it's best to reserve addresses for specific devices. Dynamic address changes can lead to connection interruptions.
There are two ways to reserve an IP address. The first is to enter a static address in the Windows network card settings (less reliable, as conflicts are possible). The second, more reliable, way is to configure MAC address binding to the IP address in the router interface. To do this, find the "LAN" or "DHCP Server" section in the router settings and select "Address Reservation."
Example of a static IP for manual configuration in Windows:IP address: 192.168.1.50
Subnet mask: 255.255.255.0
Default gateway: 192.168.1.1
DNS: 8.8.8.8 or router address
You can find out your current IP and MAC address through the command line. Click Win + R, enter cmd and run the command ipconfig /allFind the "Physical Address" line—this is the MAC address you need to enter into your router settings for backup.
Once you set up static IP addresses, your network will be predictable. You'll always know that your NAS server has a .10 address, and your media center has a .20 address. This simplifies troubleshooting and configuring third-party software that requires a resource path.
Using HomeGroup and SMB protocol
With the release of Windows 10 updates, the classic HomeGroup was retired. Microsoft is now focusing on standard sharing protocols and cloud services. However, legacy devices or older versions of Windows may require SMB 1.0 support, although this is not recommended for security reasons.
To enable the necessary components, go to Control Panel → Programs and Features → Turn Windows features on or off. Make sure "SMB 1.0/CIFS file sharing support" (if you need older devices) and "SMB 1.0/CIFS Client" are enabled.
⚠️ Warning: SMB version 1.0 has known vulnerabilities (e.g., WannaCry). Enable it only if your network includes older printers or NAS devices that don't support SMB 2.0/3.0, and be sure to install antivirus protection.
In today's environment, it's preferable to use SMB 2.0 or 3.0, which are enabled by default and provide traffic encryption. Windows 10 automatically selects the most secure protocol version when connecting to another computer. Problems may arise when connecting to very old routers with USB drives or TVs with outdated software.
If automatic detection doesn't work, you can use a direct path to the resource. Open File Explorer and enter [in the address bar] \\Computer IP address (For example, \\192.168.1.50). This will allow you to bypass detection services and connect directly if the ports are not blocked.
Diagnosing and troubleshooting
Even with proper configuration, situations may arise where computers cannot see each other. Most often, the problem lies with the Windows firewall or third-party antivirus software. Antivirus packages (Kaspersky, ESET, Avast) often have their own built-in firewalls that block the local network, classifying it as "Public."
Check your Windows Firewall settings. Go to "Windows Defender Firewall" → "Allow an app...". Make sure the "Private" and, if necessary, "Public" boxes are checked for "File and Printer Sharing."
- 🔍 Check the Print Spooler service - if it is stopped, network printers may not be displayed.
- 🔄 Reboot your router and all client devices after making changes to the settings.
- 🛡️ Temporarily disable third-party antivirus software to check its impact on the network.
Another common issue is different computer names. Make sure each computer on the network has a unique name in My Computer → Properties. If two computers have the same name (for example, WIN-USER), a conflict will occur, and one of them will not be able to function properly on the network.
In some cases, resetting your network settings can help. In Windows 10, you can do this via Settings → Network & Internet → Status → Network Reset. This will delete all saved Wi-Fi passwords and reset your network adapters to factory settings, which often resolves software conflicts.
Why is my computer visible on the network, but folders won't open?
The issue is most likely related to NTFS permissions or a disabled guest account. Check the "Security" tab in the folder's properties. Also, try disabling "Password-protected sharing" in the advanced network settings.
How do I connect to a network if auto-discovery doesn't work?
Use direct input of IP address in Explorer. Enter \\192.168.x.x in the address bar. If this doesn't help, check if a firewall on the receiving computer is blocking the connection.
Is it possible to create a local network between Windows 10 and macOS?
Yes, this is possible via the SMB protocol. On a Mac, you need to enable "File Sharing" in the system preferences, and on Windows, connect via "Map Network Drive" and specify the Mac's address. You'll need to enter the Mac username and password.
