Organizing local interaction between devices in an apartment or small office is no longer the domain of system administrators. Modern operating systems, in particular Windows 10, offer powerful built-in tools that let you share files, printers, and multimedia content in minutes. A properly configured infrastructure allows you not only to transfer documents but also to stream video from one computer to a TV or gaming console without lag.
The setup process can seem confusing due to the many hidden security settings and network profiles. However, if you follow these steps consistently, you'll create a stable environment where all your devices can see each other. In this article, we'll cover the technical nuances that beginners often overlook and help you create a reliable data exchange architecture.
It is worth understanding that local area network Local area network (LAN) and wireless LAN (WLAN) connections require the same approach to logical configuration, despite differences in the physical layer of signal transmission. The key here is correctly identifying devices and assigning them the correct access rights. Let's start with the fundamental steps without which further work is impossible.
Checking hardware and drivers
Before delving into the operating system settings, you need to ensure that the physical layer is functioning correctly. The wireless adapter must be working properly, and the drivers must be up-to-date and recommended by the manufacturer. Network visibility issues are often caused by outdated software or a disabled Wi-Fi module.
Open Device Manager to check the hardware status. To do this, press the key combination Win + X and select the appropriate item from the menu. In the "Network adapters" section, find the device that contains the words Wireless, Wi-Fi or 802.11If there's a yellow triangle next to the name, you'll need to reinstall the drivers from the official website of the laptop or motherboard manufacturer.
⚠️ Attention: Make sure Client Isolation is enabled on your router. If it's enabled, devices connected to the same access point won't be able to communicate with each other, even if your Windows settings are perfect.
It's also important to check whether the communication module itself is turned on. Some laptop models have a physical switch or function key (often Fn + F2), which software-based disables the radio module to save power. Without an active physical connection, no software settings will have any effect.
Make sure all computers you plan to connect are connected to the same wireless network. If you have a dual-band router broadcasting 2.4 GHz and 5 GHz networks with different names (SSIDs), connect all computers to one of them for maximum compatibility, although modern routers typically combine them into a single logical network.
Setting up a network profile and discovery
Windows 10 places a high priority on security, so by default, new connections are classified as "Public." In this mode, the system blocks incoming connections and hides your computer from other devices. To create a home network, you need to change the profile to "Private."
Go to the Start menu, select Settings (the gear icon), and open Network & Internet. In the left menu, select Status, then click the properties of your current connection (Wi-Fi). In the window that opens, under Network Profile, select PrivateThis action will allow the computer to be visible to trusted devices.
After changing your profile, you need to configure sharing settings. Return to the main Network and Internet window and find the "Sharing Settings" link (or "Network and Sharing Center" -> "Change advanced sharing settings"). This is where you'll find the key switches that determine the sharing logic.
In the "Private" (current) profile, do the following:
- ✅ Turn on network discovery so other PCs can see your computer.
- ✅ Enable file and printer sharing.
- ✅ Allow Windows to manage HomeGroup connections (if this feature is still available in your version).
The "All Networks" section deserves special attention. It's recommended to enable sharing here so users can access files, and select "Disable password-protected sharing" if you want to simplify access for devices within your home without constantly entering passwords. However, if you have children or guests on the network, it's best to leave the protection enabled.
Creating folders and resources for sharing
Once the network layer is configured, you need to determine what data will be accessible to other users. Simply opening the C: drive is not an option—that would violate basic security principles. You need to explicitly specify the folders that will be shared.
Select the folder you want to share (for example, "Movies" or "Work Documents"). Right-click it and select "Properties." Go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box.
☑️ Access setup checklist
In the same window, click the "Permissions" button. Here you can fine-tune permissions for the "Everyone" group or specific users. For example, you can only allow files to be read, while preventing them from being deleted or modified. This is especially useful for media libraries you want to stream to your TV but don't want someone accidentally deleting a movie.
There is also a quick way through the "Sharing" tab in the folder properties. Select "Everyone" from the list (or Everyone), click "Add" and set the permission level (Read and Write or Read-only). Once the settings are applied, the folder will be accessible over the network.
The path to the shared folder will look something like this: \\Computer_Name\Folder_NameThis is the path other users will use to access your data. You can find the computer name in the "System" section of Windows Settings.
Mapping a network drive for convenience
Constantly searching for files through the "Network" tab in File Explorer is inconvenient, especially if the folders are located deep in the directory structure. It's much more efficient to mount the remote folder as a local drive. This way, the network resource will appear in "My Computer" just like the C: or D: hard drives.
To do this, open "This PC" in File Explorer. In the top menu, select the "Computer" tab and click "Map network drive." Select any available drive letter (e.g., Z:). In the "Folder" field, enter the path to the resource or click "Browse" to locate the computer on the network visually.
There are a few things to note to ensure a successful connection:
- 🔒 Make sure the "Reconnect at logon" box is checked to prevent the drive from disappearing after a reboot.
- 🔑 If required, enter the login and password for the computer account where the folder is located.
- 📁 Use different drive letters for different resources to avoid confusion.
If the system prompts you for credentials, enter the username and password of the computer where the folder is located. If there are no accounts with the same username and password on both computers, Windows will require authorization. This is a normal security feature.
What to do if the disk does not connect?
Often, the problem lies with the Workstation service. Press Win+R, enter services.msc, find the Workstation service, and make sure it's running. Also, check if your antivirus software is blocking network connections.
Once successfully connected, you'll see the new drive in the list of devices. Now, working with files on the remote computer is no different from working with local files, significantly improving the ease of using your home network.
Setting up a home media library (DLNA)
If your goal isn't just to transfer documents, but to watch movies or listen to music on a TV, set-top box, or gaming console, standard network access may not be enough. This is where technology comes in. DLNA (Digital Living Network Alliance), built into Windows.
In Windows Search, type "Streaming" and select "Media Streaming." Click "Turn on media streaming." The system will prompt you to name your media library (for example, "MediaServer_PC"). After confirming, Windows will begin indexing your media files and making them available to compatible devices on the network.
In the streaming settings window, you can manage the device list. All receivers (TVs, consoles) found on the network are displayed here. You can allow or block access for a specific device, which is convenient if you don't want your neighbors (in case of poor Wi-Fi security) to see your files.
| Parameter | Description | Recommendation |
|---|---|---|
| Library name | Name of the server on the network | Use a descriptive name, such as LivingRoomPC |
| File formats | Supported types | MP4, MKV, MP3, JPEG are supported by default |
| List of devices | Access clients | Check the list regularly for strangers |
| Stream quality | Transmission bitrate | Leave it on Automatic to adapt to network speed. |
It's worth noting that DLNA is not a file manager. You won't be able to edit files on the server via your TV; you can only play them. For full file system functionality, it's best to use the methods described in the previous sections or specialized server programs, such as Plex or Kodi.
Diagnostics and troubleshooting
Even with proper configuration, sometimes situations arise where computers stop "seeing" each other. This could be due to driver updates, a router IP address change, or a Windows service failure. Don't panic—most problems can be resolved using standard diagnostic tools.
The built-in troubleshooting wizard is the first tool you should use. Go to Settings -> Update & Security -> Troubleshoot -> Advanced troubleshooting. Select Network Adapter and run the wizard. It will automatically check for driver issues, reset the TCP/IP stack, and attempt to restore the connection.
If automatic repair doesn't help, check the detection service. Click Win + R, enter services.msc and find the "Function Discovery Resource Publication" service. Make sure the startup type is set to "Automatic" and the service is running. This service is responsible for displaying your computer in the network neighborhood.
⚠️ Attention: Third-party antivirus programs (Kaspersky, ESET, Avast) often have their own built-in firewalls that can block local networks, ignoring Windows settings. Check the network settings in your antivirus interface and add the local network to the trusted list.
It is also useful to check if the computers are on the same subnet. Open the command prompt (cmd) and enter the command ipconfigCompare the IPv4 addresses on different computers. The first three numbers (e.g., 192.168.1) must match. If one computer has the address 192.168.1.5 and the other has 192.168.0.5, they are on different networks and will not see each other.
In rare cases, a complete reset of network settings can help. In the "Network & Internet" section, at the very bottom, there's a "Network Reset" button. Click it, and the system will reinstall your network adapters and reset all settings to factory defaults. After rebooting, you'll need to re-enter your Wi-Fi password and configure the "Private" profile.
Frequently Asked Questions (FAQ)
Why can my computer see the network but not other computers?
Most likely, your network profile is set to "Public." In this mode, Windows hides your PC for security purposes. Go to Wi-Fi settings and switch the profile to "Private." Also, check if "Discoverability" is enabled.
Is it possible to create a network without a router (computer-to-computer)?
Yes, it's called an ad-hoc network. However, in Windows 10, this feature is hidden and requires using the command prompt (cmd) to create a virtual adapter. It's easier and more stable to use even the cheapest router or the "Mobile Hotspot" mode if you only need to transfer files.
How do I find out the IP address of another computer on the network?
If the computer is visible on the network, right-click it in File Explorer (under "Network") and select "Properties." The IP address will be listed in the window that opens. Alternatively, on the target computer itself, enter the following command in the command line: ipconfig.
Is it safe to disable password when sharing?
For a home network where all devices are under your control and the Wi-Fi is protected by a complex password (WPA2/WPA3), disabling password protection is convenient. However, if your neighbors can connect to your Wi-Fi, it's better to leave passwords enabled or create a guest network without access to local resources.
Why does the speed drop when transferring files over Wi-Fi?
A wireless network shares bandwidth among all devices and is susceptible to interference. For large files (over 10 GB), it's best to use an Ethernet (LAN) cable. If a cable isn't possible, make sure you're using the 5 GHz band, which is less congested and faster than the 2.4 GHz standard.
