Modern users often face the need to quickly transfer large amounts of data between devices. Flash drives get lost, cloud storage takes time to load, and cables can simply be left lying around in a closet. It's in these situations that a local wireless network comes in handy, allowing you to connect devices. laptop and desktop computer into a single system.
Setting up such a connection allows access to shared folders, printers, and multimedia files without any fuss. You don't need to be a network engineer to set up data exchange over the air. All you need is a working Wi-Fi router and basic skills in working with the Windows operating system.
In this article, we'll cover every step of the setup process, from checking your equipment to troubleshooting common errors. You'll learn how to create shared resources and securely manage access to them. This solution is ideal for homes and small offices.
Preparing equipment and checking the network
Before you start setting up, you need to make sure that both devices are in the same conditions. Local area network This will only work if both the laptop and the computer are connected to the same router. It doesn't matter whether they're wireless or one is connected via cable, as long as they share a single access point.
Check the connection status on both devices. The Wi-Fi or monitor icon in the system tray should show an active connection without yellow exclamation marks. If you're using a public network or a network with a "Public" port, Windows may block visibility to other devices for security reasons. security.
⚠️ Important: Make sure discovery is enabled on both devices. In public places (cafes, airports), this setting can make your files visible to strangers, so only perform this setting on a trusted home network.
It's also worth checking that both computers have up-to-date network adapter drivers installed. Outdated software can cause unstable connections or a complete loss of visibility into the network environment.
Setting up sharing options in Windows
The next step is to correctly configure the network settings in the operating system. Windows may hide your computer from other devices by default, so you need to enable sharing mode. To do this, go to Control Panel → Network and Internet → Network and Sharing Center.
In the left part of the window, select "Change advanced sharing settings." This will open your current network profile (private or guest). This section contains the key switches responsible for visibility your PC.
- 📡 Turn on network discovery - allows other devices to see your computer.
- 💾 Enable file and printer sharing — allows access to shared resources.
- 🔐 Use 128-bit encryption - ensures the protection of transmitted data.
After activating these options, be sure to save the changes by clicking the "Save Changes" button. Without this step, all further actions will be useless, as the system will continue to block incoming connection requests.
It's important to note that the interface may differ slightly in some versions of Windows 10 and 11, but the logic remains the same. If you can't find the options you need, use the system search and enter the phrase "manage advanced sharing settings."
Create a shared folder for file sharing
Once the network settings are applied, you need to determine what data will be available for sharing. The easiest way is to create a new folder on the drive, for example, Shared_Files, and configure its access rights. This will prevent confusion and accidental transfer of system files.
Right-click the created folder and select "Properties." Go to the "Sharing" tab. Click "Advanced" and check the box next to "Share this folder."
☑️ Checking folder access
Next, you need to configure user rights. Click the "Add" button, enter a name Everyone (or "Everyone") and confirm the action. In the permissions list for this group, check "Full Control," "Modify," and "Read." This will allow the second computer to not only read files but also write new ones.
Don't forget to also go to the "Security" tab in the folder properties. There, permissions should also be specified for the "Everyone" user or group. Users often forget this step, resulting in an access error when attempting to write to the folder, despite the correct network settings.
Search for a computer in the network environment
Now that both devices are ready, you can proceed to the actual connection. Open File Explorer on your laptop and find "Network" in the left navigation panel. If your settings are correct, you should see the name of your desktop computer.
If the computer doesn't show up immediately, try entering its IP address or name directly into the address bar of File Explorer. The input format looks like this: \\Computer_Name or \\192.168.1.XXYou can find out the IP address of the target PC through the command line by entering the command ipconfig.
| Parameter | Description | Where to find |
|---|---|---|
| Computer name | Unique name on the network | System properties |
| IP address | Digital address of the device | The ipconfig command |
| Working group | Logical group name | Additional system parameters |
| State | Connection status | Network and Sharing Center |
When you first connect, the system may request credentials. You'll need to enter the login and password for the user account on the computer whose folders you're accessing. This is a standard data protection procedure.
What should you do if it asks for a password but you don’t remember it?
If you haven't set a password for the account, try entering the username and leaving the password field blank. In some cases, you may need to create a new user with a password specifically for network access to avoid access conflicts in Windows 10/11.
Once you've entered the information successfully, the folder will open, allowing you to work with the files as if they were on your local drive. For convenience, you can right-click the network folder and select "Mount as network drive," assigning it a drive letter.
Remote desktop control
In addition to file transfer, connecting a laptop to a computer is often required for remote control. Windows has a built-in feature Remote Desktop (Remote Desktop), which allows you to see the screen of another PC and control it with a mouse.
To use this feature, remote connections must be allowed on the target computer (the one you are connecting to). This is done in the section System → Remote Access SettingsPlease note that Windows Home edition does not support host (server) function, it can only connect.
- 🖥️ High response speed when connected via Wi-Fi 5 and 6.
- 🔒 Session encryption via RDP protocol.
- ⌨️ Ability to forward local resources (printers, clipboard).
Launch the Remote Desktop Connection app, enter the IP address or computer name, and click "Connect." The system will prompt you for the remote PC's username and password.
This method is ideal for technical support or working with a powerful desktop PC from a less powerful laptop. All calculations will be performed on the main computer, and the laptop will act only as a terminal.
Using third-party software to transfer data
If the standard Windows tools seem too complex or unstable, you can always use third-party programs. There are many utilities that create their own data transfer protocol, bypassing system limitations.
One of the popular solutions is the program Resilio Sync or SyncTrayzor (based on Syncthing). They work on a P2P basis and don't require complex network permissions. Simply install the app on both devices and specify the folders to sync.
⚠️ Important: When using third-party software, pay attention to your firewall settings. Your antivirus may block the program, considering its network activity suspicious. Add the application to the exceptions list.
Another option is to use instant messaging apps that support file transfer or cloud services with LAN synchronization. However, for regular work with large volumes of data (4K video, project source files), specialized software or the native Windows network remain the most effective.
The method you choose depends on your specific needs. Messenger is suitable for a one-time photo transfer, a network folder is suitable for daily project work, and a remote desktop is suitable for accessing your workspace from another room.
Diagnosing and resolving connection problems
Even with careful setup, issues may still occur. Most often, the problem lies with the network profile. If Windows detects your home network as "Public," it will automatically disable discovery. Change the profile to "Private" in the Wi-Fi settings.
Another common cause is different versions of the SMB protocol. Older computers may use SMBv1, which is disabled by default in newer Windows for security reasons. Enabling it is not recommended; it's better to update the settings on your older PC.
It's also worth checking the "Discovery Provider Host" service. If it's stopped, your computer won't show up in Network Neighborhood. You can start it via services.msc, finding the appropriate item in the list and selecting "Run".
If all else fails, try temporarily disabling your antivirus and Windows Firewall for diagnostics. If the connection reappears after this, the issue lies with your traffic filtering rules, which need to be configured correctly.
Why does the computer see the network, but not other devices?
Most likely, both devices have Network Discovery enabled, but they are in different workgroups or have the same name. Also, check if your antivirus software is blocking local traffic.
What is the maximum transfer speed for Wi-Fi?
Speed depends on the Wi-Fi standard (n, ac, ax) and the distance from the router. Under ideal conditions, Wi-Fi 5 (AC) can achieve 40-80 MB/s real-world speed, which is comparable to fast USB 2.0 but slower than USB 3.0.
Is it safe to keep sharing enabled all the time?
On a home network with a secure Wi-Fi password, yes. If you frequently have guests over and connect them to Wi-Fi, it's best to use a guest network, isolated from the main network where your PCs are located.
Is it possible to connect a laptop to a PC without a router?
Yes, you can create a direct computer-to-computer connection (Ad-Hoc network) or share Wi-Fi from one laptop and connect to another. However, the speed and stability will be lower than connecting through a router.
How to find out the IP address of a computer on the network?
Open command prompt (cmd) and enter the command ipconfigYou're interested in the "IPv4 address" line. It usually looks like 192.168.0.X or 192.168.1.X.
