Creating a local network between a desktop computer and a laptop is a basic skill that opens up a wide range of possibilities for exchanging data without the need for external drives. In the era of cloud storage and instant messaging, direct LAN sharing Wireless is often the fastest way to transfer large files, such as 4K movies or system backups. Modern wireless technologies make it possible to set up such a connection in minutes, provided you know the right steps.
The main difficulty for users lies not in the physical connection, since both devices are already on the same wireless network, but in the operating system's software settings. Windows blocks external connections by default in order to security, considering new networks as public. For computers to "see" each other, it's necessary to change the network profile and activate the appropriate discovery services.
In this guide, we'll walk you through every setup step, from hardware testing to forwarding specific folders for sharing. You'll learn how to avoid common errors related to firewalls or SMB protocol version incompatibilities. You'll be up and running in no more than 15 minutes, after which you'll have full access to resources on both devices.
Checking equipment and preparing devices
Before you begin software configuration, you need to ensure the physical infrastructure is ready. The key element here is Wi-Fi router, which should correctly distribute the internet and allow devices to exchange data within its subnet. If your laptop and PC are connected to different frequency bands (2.4 GHz and 5 GHz), this is usually not a problem, as modern routers combine them into a single local network. However, in rare cases, client isolation testing may be required.
Make sure both devices have the latest wireless adapter drivers installed. Outdated software can cause an unstable connection or limit data transfer speeds. It's also important that both computers are within a strong signal range, as packet loss during large data transfers will result in a sharp drop in speed or even a disconnection.
Check the IP addresses of your devices. For proper operation, they must be in the same subnet, meaning they must differ only in the last digit (e.g., 192.168.1.5 and 192.168.1.10). If the addresses are significantly different (e.g., 192.168.0.x and 192.168.1.x), the devices will not find each other without manually configuring routing.
- 📡 Make sure both devices are connected to the same Wi-Fi network (SSID).
- 💻 Check that the Wi-Fi adapter drivers are installed and working without errors.
- 🔌 Disable VPN clients during setup, as they can mask your real IP address.
- 🔋 It is recommended to disable the power saving mode for the Wi-Fi adapter on your laptop to prevent it from going to sleep during transmission.
⚠️ Note: If you're using a guest Wi-Fi network (Guest Network), creating a local network will not be possible. Routers specifically isolate guests from each other and the main network for security purposes.
Setting up a network profile and discovery
The first software step is to change the network profile from "Public" to "Private." In the public profile, Windows hides the computer from other devices, blocking incoming discovery requests. This is standard protection in cafes and airports, but at home it prevents the creation of local network.
To change your profile in Windows 10 and 11, open "Settings" from the Start menu and go to "Network & Internet." Select "Wi-Fi," then click on your connection name. In the menu that opens, find "Network Profile" and set the radio to "Private." This will allow discovery by devices you trust.
Next, you need to enable discovery services. Go to "Control Panel" → "Network and Sharing Center" → "Change advanced sharing settings." Here, expand the "Private" section and enable "Turn on network discovery" and check "Turn on automatic configuration of connecting network devices."
Don't forget to enable "File and Printer Sharing" in this same menu. Without this option, even if computers see each other in the network list, they won't be able to access shared resources. Save your changes by clicking "Save Changes" at the bottom of the page.
- 🛡️ Change the network type to "Private" in the Wi-Fi settings.
- 🔍 Turn on network discovery in Advanced sharing settings.
- 📁 Enable file and printer sharing.
- 💾 Disable password protection (optional, to simplify access on your home network).
⚠️ Note: The settings interface may vary slightly depending on your Windows build version. If you can't find the option, try searching for "general" in system settings.
Creating a shared folder for data exchange
After configuring your network settings, you need to create an access point—a folder whose contents other devices can access. You can share an existing directory or create a new one specifically for network files. Give it a descriptive name, for example, Share or Exchange, so you can easily find it in your network environment.
To configure access, right-click the folder and select "Properties." Go to the "Sharing" tab and click "Advanced." Check "Share this folder." Below, in the "Permissions" button, ensure that the "Everyone" group has "Read" or "Full Control" permissions if you plan to not only download but also save files from another computer.
☑️ Checking folder access
There's a second level of security settings—the "Security" tab in the folder's properties. You'll also need to add a user here. All (or All) and grant it the appropriate permissions. If this is not done, Windows may block access, citing NTFS permission errors, even if network access is allowed.
For convenience, you can copy the network path to the folder. In the advanced access settings window, there is a "Network Path" field, which contains an address like this: \\ComputerName\FolderThis path can be copied and pasted into the address bar of File Explorer on the second device for instant access.
| Parameter | Recommended value | Description |
|---|---|---|
| Name (Share Name) | Up to 12 characters, Latin | It is better to avoid Cyrillic letters and spaces for compatibility. |
| Permissions | Read/Change | Full access is only needed to write files. |
| Caching | Only files needed for offline work | Speeds up access to frequently used documents |
| User restrictions | 10 (standard) | Maximum simultaneous connections in home OS |
Connecting to a network resource from a laptop
Now let's move on to the second device—the laptop. Open File Explorer and enter the IP address of the first computer in the address bar (e.g., \\192.168.1.5) or its network name (\\DESKTOP-PC). Using an IP address is more reliable, since names may sometimes not be resolved by the DNS service within the local network.
If the settings are correct, a window with a list of shared folders will open. The first time you connect, the system may ask for credentials. Enter the login and password for the user account on the primary computer (the one where the folder is located). If you disabled password protection in your network settings, you should be logged in automatically.
What to do if Windows says "Access Denied"?
Often, the issue lies with the Workstation service or with ports blocked by your antivirus software. Try temporarily disabling your third-party antivirus and checking access. Also, ensure that the Discovery Resource Publishing service is running on both PCs.
For constant convenience, you can map a network folder as a separate drive. In File Explorer, click "This PC," then select "Map network drive" from the top menu. Select any available drive letter (e.g., Z:) and specify the path to the folder. Check "Restore at logon" to make the drive accessible after a reboot.
File copy speed over Wi-Fi depends on the wireless standard. On the 2.4 GHz band, actual speeds rarely exceed 3-4 MB/s, while on the 5 GHz band with standard support AC or AX You can achieve speeds of 20-50 MB/s and higher. This is sufficient for watching videos directly from a disk or working with documents.
- 💻 Enter the IP address of the main PC in the address bar of the File Explorer.
- 🔑 Enter the primary PC administrator login and password when prompted.
- 💾 Use the "Map network drive" feature for convenience.
- ⚡ Expected speed depends on the Wi-Fi router standard.
⚠️ Note: If you changed the password on your primary computer, your saved Windows credentials may no longer work. You'll need to re-enter your current password through the Credential Manager.
Solving typical problems and errors
Despite the ease of setup, users often encounter situations where computers cannot see each other. One of the most common causes is a disabled service. SMB 1.0 Or, conversely, its presence in older systems. In modern Windows 10/11, SMB 2.0/3.0 is enabled by default, which is more secure, but if one of the computers is very old (for example, running Windows XP), protocol version conflicts may arise.
Another common issue is the firewall. Antivirus software or the built-in Windows Defender may block incoming connections, deeming them suspicious. Check the list of allowed applications in the firewall and ensure that "File and Printer Sharing" is checked in the "Private" column.
It's also worth mentioning the issue with names. If you use Cyrillic computer names, in rare cases encoding errors may occur when attempting to connect. In such cases, using the IP address is the only reliable solution. To find the IP address, use the command ipconfig in the command line.
C:\Users\User> ipconfigWireless LAN adapter Wi-Fi:
IPv4 address......: 192.168.1.55
Subnet mask.........: 255.255.255.0
Default gateway..........: 192.168.1.1
Multimedia organization and streaming
A local Wi-Fi network opens up opportunities not only for file copying but also for streaming content. You can store your movie and music collection on a powerful desktop PC and watch them on a laptop, tablet, or Smart TV without downloading anything. This can be done using DLNA servers or the built-in Windows Media Server features.
To activate the built-in media server, select "Streaming Media" in the Network and Sharing Center and enable it. This will allow other devices on the network to see your video and audio files as available for playback. However, for more flexible control, it's better to use specialized software, such as Plex or Kodi.
When streaming high-resolution video (4K HDR), Wi-Fi bandwidth requirements increase. An unstable signal can lead to buffering. In this case, it's recommended to use a wired connection at least for the content source (PC), leaving the laptop on Wi-Fi, or ensure a direct, unobstructed signal path between the devices and the router.
- 🎬 Enable media streaming in network settings.
- 📺 Use client applications (VLC, MX Player) to access network folders.
- 🚀 For 4K video, the 5 GHz Wi-Fi standard is preferred.
- 🎵 Music libraries are available for playback on any device on the network.
⚠️ Note: Streaming features may vary depending on your Windows version and the codec installed. Some video formats may not play on a Smart TV without first transcoding on a PC.
FAQ: Frequently Asked Questions
Is it possible to create a local network without a router, directly between a laptop and a PC?
Yes, it's possible. You can set up a computer-to-computer (Ad-hoc) network using Wi-Fi adapters, but in Windows 10/11, this feature is hidden and requires creating a special script or using the command line. It's easier and more stable to connect them directly with an Ethernet cable or use a router even without an internet connection.
Why can computers see each other, but the folder won't open?
The issue is most likely related to access rights in the "Security" tab or blocked ports by your antivirus software. Also, check that the time and date match on both devices—a large time difference can block authorization in the Windows domain structure.
How do I find out the IP address of another computer on the network?
On the target computer, click Win + R, enter cmd and press Enter. In the black window, enter the command ipconfigYou're interested in the "IPv4 address" line. You can also see the IP address in the router interface's DHCP Client List.
Will the local network work if the provider disconnects the Internet?
Yes, the local network operates regardless of internet access. The router continues to function as a switch, transmitting data between devices within your home network, even if the ISP cable is disconnected.
