How to connect a PC and laptop via Wi-Fi: a complete guide

Today's digital lifestyle often requires the rapid transfer of large amounts of data between devices. Using external hard drives or flash drives becomes inconvenient when syncing work projects or media files daily. Creating a local network via Wi-Fi allows you to integrate a desktop computer and laptop into a single ecosystem, providing instant access to resources on both devices.

A wireless connection eliminates the need to run long cables across an entire apartment or office. This doesn't require complex equipment; all you need is for both devices to be within range of the same wireless router. Local area network opens up opportunities not only for file sharing, but also for sharing printers or even game servers.

In this article, we'll walk you through every step of the setup process, from checking basic settings to troubleshooting common errors. You'll learn how to properly set up sharing in the Windows operating system and ensure the security of your data transfers. Microsoft has provided convenient tools for such situations, which we will use.

Preparing equipment and checking the network

The first step to a successful connection is ensuring physical connectivity. Make sure your router is turned on and distributing internet, and both devices—the PC and laptop—are connected. It doesn't matter whether you're using the 2.4 GHz or 5 GHz frequency, as long as they're on the same network segment.

Check the connection status on both devices. A Wi-Fi icon with a partially or fully filled bar should appear in the notification area in the lower right corner of the screen. If one device is connected via cable (Ethernet) and the other via wireless, the connection will still work, but the speed may be limited by the wireless channel.

It's important that the network profile is detected correctly by the system. Windows divides connections into "Public" and "Private." To create a local network, a private profile is required, as it allows the device to be discovered by other network members.

⚠️ Warning: If you're in a public place (cafe, airport), creating an open local network may be unsafe. Make sure you trust your surroundings or use additional security measures.

• 📶 Make sure both devices can see the same Wi-Fi network.
• 🔌 Check if the WLAN indicator on the router is on.
• 💻 Make sure your wireless adapter drivers are installed and working correctly.

Setting up sharing options in Windows

After the physical connection, you need to configure the operating system software. Windows 10 and 11 have similar settings interfaces, although the paths to them may differ slightly. Open the Control Panel or System Settings to find the section responsible for networking.

You need to go to the Network and Sharing Center. Here you'll find the key switch that makes your computer visible to others. Find the "Change advanced sharing settings" option.

In the window that opens, you'll see several profiles: private network, guest network, and all networks. We need the first option. Enable "Turn on network discovery" and check "Turn on file and printer sharing."

Don't forget to save your changes by clicking the corresponding button at the bottom of the page. Without this step, all further actions will be useless, as the system will block incoming connection requests.

Create a HomeGroup or set up sharing

In older versions of Windows, there was a concept called "HomeGroup," which made life much easier for users. In modern versions, Windows 10/11 This functionality has been removed in favor of a more flexible, but slightly more complex, manual folder configuration.

Now you need to select the specific folder you want to share. This could be a directory containing documents, photos, or movies. Right-click the folder, select "Properties," and then go to the "Sharing" tab.

Click the "Sharing" button and select "Everyone" from the drop-down list. Add the user and set the permission level: "Read" will only allow viewing files, while "Read and Write" will give full control, including deletion and modification.

After applying the settings, the system may prompt you to confirm the action or enter an administrator password. This is a normal security response, preventing accidental access to critical system files.

Search for connected devices and connect to them

Once the settings on the first computer (the server) are complete, move on to the second device (the client). Open File Explorer and find the "Network" section in the left navigation panel. All available devices on the local network should be displayed here.

If you see the name of your primary PC, the setup was successful. Double-clicking the computer's name will open a list of shared folders. The system may prompt you for credentials the first time you connect.

Enter the username and password for the user account on the primary computer. If there is no password, signing in may fail, as Windows security policies often require a password for network access.

For convenience, you can map a network folder as a separate drive. To do this, right-click the desired folder in the File Explorer window and select "Map network drive." Select any available drive letter, such as Z:, and click "Done."

Direct laptop-to-laptop or PC-to-PC connection without a router

There are scenarios where you don't have a router handy but need to transfer files urgently. In this case, you can create a direct connection between devices, using one as an access point. This is especially useful when traveling or when infrastructure is lacking.

Enable the "Mobile Hotspot" mode on one of your laptops. This feature turns Wi-Fi adapter Connect your computer to a mini-router. Go to Network and Internet settings, find the appropriate section, and turn on the toggle switch.

Set a network name and password. Then connect the second device to the created network as you would a regular Wi-Fi hotspot. Once connected, the process repeats: configure sharing in the created network profile.

⚠️ Please note: When connecting directly, the data transfer speed will be limited by the capabilities of the Wi-Fi adapter and may be lower than when connected via a gigabit router.

This method is convenient for quickly transferring files, but is not suitable for continuous operation, since one of the computers must constantly maintain an active access point, which consumes resources.

Troubleshooting and common errors

Even with proper configuration, situations may arise where computers cannot see each other. Most often, the problem lies with a firewall or antivirus software that blocks local connections, deeming them suspicious.

Check Windows services. Click Win + R, enter services.msc and find the services related to network discovery (Function Discovery Resource Publication, SSDP Discovery). They should be started and running in automatic mode.

It's also worth making sure that both devices have the same workgroup names. By default, this is WORKGROUPYou can change this in the system properties, although in modern versions of Windows this is rarely necessary.

If all else fails, try temporarily disabling your third-party antivirus. It's often a hidden blocker of local ports required for the SMB protocol.

Comparison of data transfer methods

The connection method you choose depends on your goals. A local network via Wi-Fi isn't the only option. Let's compare it with other popular methods so you can choose the best one for your situation.

As the table shows, Wi-Fi is slower than cable, but offers the convenience of being free of wires. This is the perfect balance for everyday document management.

Security and data protection in the local network

By sharing files, you potentially open the door to unwanted intruders if you neglect basic security rules. Your account password is your first and most important line of defense.

Don't use a simple guest network to transfer sensitive data. If you have unauthorized devices on your network (such as a guest's smartphone), ensure they are isolated from your computers using the "Guest Network" feature on your router.

Update your router firmware regularly. Vulnerabilities in router software can allow hackers to access your local network from outside, even via Wi-Fi.

⚠️ Please note: Router interfaces and Windows versions are constantly being updated. Button locations and menu item names may differ from those described. Always consult the official sources from your equipment manufacturer.

Use complex passwords for your Wi-Fi network. Simple combinations like "12345678" are easily cracked, giving access to all devices on the network, including shared folders.
