Creating a local area network (LAN) in the Windows 10 operating system via a wireless connection is a fundamental task for any modern user who wants to unite their devices into a single ecosystem. Previously, this required wires, complex IP address settings, and a deep understanding of network protocols, but today Windows 10 significantly simplified the process, making it accessible even to beginners. However, despite the automation, many users encounter problems with computers "not seeing" each other or unable to exchange files without additional manipulation.
The main difficulty lies not so much in the physical connection to the router, but in properly configuring security profiles and permissions within the operating system itself. Microsoft has implemented a number of security mechanisms that, by default, hide your PC from prying eyes on public networks, which is an excellent security measure, but it hinders your work at home. In this article, we'll discuss how to properly configure them. private network, activate the necessary services and ensure stable data exchange between laptops, tablets and desktop PCs.
You will find out which parameters need to be changed in Network and Control Center, how to properly share folders and printers, and what to do if standard device discovery methods don't work. We'll cover not only the software but also the nuances of Wi-Fi adapters, which are often overlooked when diagnosing problems. Understanding these processes will allow you to create a reliable infrastructure for multimedia, gaming, or document collaboration.
Preparing equipment and checking connections
Before you begin complex configurations within Windows, you need to ensure that the physical foundation of your network is working correctly. All devices you plan to connect must be connected to the same network. Wi-Fi routerIt doesn't matter whether you use a single router or a mesh system of multiple access points, as long as they are on the same network segment and receive IP addresses from the same DHCP server.
Check the connection status on each computer. A Wi-Fi icon indicating a connection should appear in the notification area in the lower right corner of the screen. If one of the devices shows a "Star" or "No Internet Access" icon, further network setup is pointless, as a basic connection is missing. Ensure that the wireless adapter drivers are installed correctly and are working without conflicts.
⚠️ Attention: If you have a dual-band router that broadcasts two networks (for example, MyWiFi_2.4 And MyWiFi_5G), make sure all devices are connected to one of them. Although modern routers often isolate clients between bands, in rare cases, older settings may prevent them from being visible to each other.
You can use the built-in command line utility for diagnostics. Open a terminal and enter the command ipconfig, to your IP address. The addresses of all computers on the local network must begin the same way, for example, 192.168.0.x or 192.168.1.x, Where x — is a unique device number. If the prefixes match, a logical connection at the TCP/IP protocol level has already been established.
Setting up a network profile and discovery
Choosing the right network profile is key to setting up local network connectivity. When you first connect to a new Wi-Fi network, Windows 10 asks if you want to make your computer discoverable to other PCs. If you answer "No" or accidentally select the "Public Network" profile, the system will apply strict firewall rules, blocking incoming connections.
To fix this, you need to go to your network settings. Click on the Wi-Fi icon, select "Properties" for the current connection, or go through Settings → Network & Internet → Wi-Fi → Manage known networksHere you need to find the name of your home network and switch the profile from “Public” to "Private"This action confirms to the system that you are in a secure environment and allow data exchange.
After changing your profile, it is important to enable discovery features. Go to Control Panel → Network and Sharing Center → Change advanced sharing settingsIn the "Private (current profile)" section, you need to enable the following options:
- 📡 Enable network discovery (and installation of network devices).
- 💾 Enable file and printer sharing.
- 🔐 Allow Windows to manage HomeGroup connections (if available).
Don't forget to save your changes by clicking the corresponding button at the bottom of the page. Without these steps, your computer will be hidden from other network users, even if they are technically connected to the same router. This is the basic setup, without which further work is impossible.
Expanding sharing of folders and files
Once the devices have "seen" each other, it's time to configure the resources you want to share. Windows 10 offers two main options: using a dedicated "Shared Documents" folder or sharing any folder on the drive. The first option is simpler, while the second is more flexible and convenient for regular use.
To configure a custom folder, right-click it and select "Properties." Go to the "Sharing" tab and click "Advanced." Here, check the "Share this folder" box. Next, click "Permissions" to fine-tune who can access files: read only, modify, or fully control their contents.
| Permission type | Description of action | Recommended use |
|---|---|---|
| Full access | Reading, writing, modifying, and deleting files | Personal folders on trusted PCs |
| Change | Read, write, and delete, but without changing access rights | Working projects, general documents |
| Reading | View and copy files only | Media libraries, archives |
It's important to remember security: don't grant full access to system folders or the root of the C: drive to all network users. This can create vulnerabilities that attackers can exploit if they somehow gain access to your Wi-Fi. Always adhere to the principle of least privilege.
⚠️ Attention: If you are trying to open a shared folder from another computer and the system asks for a login and password, make sure that you are entering the credentials of that particular computer. where is the folder located, not the one you're connecting from. The login must match the username on the host.
Organizing printer sharing
One of the most useful features of a local network is the ability to share a single printer with everyone in the family or office. Instead of connecting the device via USB to a single PC and then sharing it, modern network printers can be connected directly to the router via Wi-Fi or a LAN cable.
If your printer is connected via USB to one of the computers on the network, you can make it a network printer. To do this, go to Settings → Devices → Printers & Scanners On the host computer. Select the desired printer, click "Manage," then "Printer Properties," and then go to the "Sharing" tab. Check the "Share this printer" box and give it a meaningful network name.
On client computers (from which printing will take place), you need to add a network printer. This can be done through the "Add Printer" menu in the same device settings. The system will search for available printers on the network. If the automatic search fails, you can add the device manually by specifying its IP address or network path in the following format: \\ComputerName\PrinterName.
What should I do if the printer driver is not found automatically?
If Windows can't find a driver for your network printer automatically, you'll need to download the latest driver from the manufacturer's website for your OS version. When adding the printer, select "Install driver manually" and specify the path to the downloaded file. Installing the driver as if it were a local printer, creating a new Standard TCP/IP port, often helps.
It's worth noting that for a network printer connected via USB to work, the host computer must be turned on. If the host computer is turned off or in sleep mode, printing from other devices will be impossible. In such cases, it's better to consider purchasing a printer with a built-in Wi-Fi module or a Wi-Fi router with a USB port to connect the printer directly to the network.
Access to multimedia and home libraries
A local network offers excellent opportunities for setting up a home media server. You can store movies, music, and photos on a single powerful computer or NAS drive and play them on a TV, tablet, or another PC without having to copy files.
To implement this scenario, technology is used DLNA (Digital Living Network Alliance). This feature is built into Windows 10 and is called "Media Streaming." To enable it, search for "Media Streaming Settings" in the Start menu. In the window that opens, click "Turn on media streaming."
The system will prompt you to select devices that are allowed to access your libraries. You can allow access to all devices on the network or select specific TVs and set-top boxes from a list. After confirmation, Windows will index the default folders (Videos, Music, Pictures) and make them available for playback over the network.
- 🎬 Movies and TV series can be played directly on your Smart TV.
- 🎵 Music collections are streamed to wireless speakers.
- 📸 Photos from your computer are displayed on digital photo frames.
For more advanced users who lack the functionality of standard DLNA, there are specialized server applications such as Plex, Kodi or EmbyThey allow you to create beautiful interfaces with movie posters, descriptions, and cast lists, turning an ordinary PC into a full-fledged media center.
Diagnosing problems and troubleshooting errors
Despite its apparent simplicity, creating a local Wi-Fi network can sometimes be fraught with technical difficulties. Computers may not be able to see each other, access may be blocked by antivirus software or a firewall, and data transfer speeds may be unacceptably slow. Understanding the causes of these problems will help you quickly resolve them.
One of the most common causes is mismatched workgroup names. Although this requirement has become less stringent in modern versions of Windows, it is recommended that all computers have the same workgroup name. By default, this WORKGROUPYou can check and change this in System properties (team sysdm.cpl).
It's also worth checking your Windows services. Make sure the following services are running and in automatic mode:
- 🛠 Publishing discovery resources.
- 🔍 Discovery Provider Host.
- 📡 SSDP Discovery.
If you are not satisfied with the file transfer speed over Wi-Fi, check the frequency band your connection is operating on. Standard 802.11n/ac/ax The 5 GHz band provides significantly higher speed and stability than the older 2.4 GHz band, which is often congested with neighboring routers and household appliances.
⚠️ Attention: Third-party antivirus programs (Kaspersky, ESET, Avast, etc.) often have their own built-in firewalls that can block your local network, ignoring Windows settings. If all else fails, temporarily disable network protection in your antivirus or add your Wi-Fi network to the trusted list in the antivirus settings.
☑️ Network Diagnostic Checklist
In some cases, resetting network settings helps. In Windows 10, this can be done via Settings → Network & Internet → Status → Network resetThis operation will reinstall your network adapters and reset all settings to factory defaults, which often solves mysterious connection problems.
Frequently Asked Questions (FAQ)
Is it possible to create a local network without a router, directly between two laptops?
Yes, this is possible. This type of network is called an Ad-Hoc network. In Windows 10, this can be done via the command line by creating a virtual access point or using the Mobile Hotspot feature. However, for stable operation and internet access on both devices, it's best to use a router.
Why am I asked for a password when accessing the package, even though both PCs have the same password?
Windows verifies the remote machine's credentials. You need to either create an identical user (with the same name and password) on both computers, disable password protection in the sharing settings (not recommended for security reasons), or enter the remote PC user's login and password when prompted.
How do I find out my computer's IP address on a local network?
Open command prompt (cmd) and enter the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter. It usually looks like 192.168.xx.
Does internet speed affect file transfer speed within the network?
No, it doesn't. The speed of copying files between computers on a local network depends only on the speed of your Wi-Fi router, signal quality, and the speed of your hard drives. Your internet connection isn't involved in this process unless you use cloud services.
Is it safe to keep file sharing enabled?
If you have the "Private" network profile configured correctly and a strong Wi-Fi password, your connection is safe. However, if you frequently connect to public Wi-Fi (such as cafes or airports), be sure to switch to the "Public" profile to hide your files from prying eyes.
