How to Connect Two PCs via Wi-Fi: A Complete Guide

Modern users often face the need to quickly transfer large amounts of data between devices. Cloud storage and messaging apps are convenient for documents, but they are too slow for hundreds of gigabytes of video or games. In this situation, local area network becomes the only effective solution that allows you to utilize the full bandwidth of your router.

Establishing a wireless connection between two computers doesn't require complex equipment or paid software. All you need is for both devices to be within range of the same router and have the correct Windows settings. Wi-Fi Direct or a classic LAN network allows you to create a complete environment for file sharing, project collaboration, or online gaming.

In this guide, we'll walk you through every step of the setup process, from basic security settings to advanced sharing methods. You'll learn how to avoid common mistakes that often prevent devices from being visible to each other. Proper Configuration SMB protocol and network profiles guarantee a stable connection without any hassle.

Checking requirements and preparing equipment

Before beginning setup, ensure your infrastructure is ready for operation. Both computers must be connected to the same wireless network. If one PC is connected via cable and the other via Wi-Fi, connection is also possible, but configuration may require additional steps in the router settings.

It is critical that both devices have an operating system that supports data exchange standards such as SMB 2.0/3.0Windows 10 and Windows 11 support these protocols by default, but older versions (Windows 7) may require manual changes to the registry or enabling additional components.

Make sure your wireless adapter drivers are updated to the latest version. Older software may not correctly handle multicast traffic, which is necessary for discovering devices on the network. Also, check that your antivirus or built-in firewall isn't blocking local connections.

⚠️ Note: If you're using a guest network on your router, devices may be isolated from each other by default. To create a local network, disable "AP Isolation" in your router settings or switch to the main network.

There are several ways to set up communication, and the choice depends on your goals. A standard network environment is suitable for simple file transfer, while remote control requires specialized services.

• 📡 Classic LAN: Both PCs are connected to the same router, and the exchange goes through it.
• 🔗 Ad-hoc network: creating a direct connection between PCs without a router (requires support from adapters).
• ☁️ Virtual network: using programs like Hamachi or Radmin VPN to emulate a local connection over the Internet.

Setting up a network profile and discovery

The first step in connecting two PCs via Wi-Fi is to correctly configure the network profile in Windows. By default, the system often assigns the "Public" profile, which hides the computer from other devices for security reasons. We need to change this status to "Private."

To do this, go to Settings → Network & Internet → StatusIn the "Properties" section of your Wi-Fi network, select the "Private" network type. This will make your computer visible to other devices and open ports for local data exchange. Without this step, the other settings may not work.

Next, you need to activate the detection functions. Open Control Panel → Network and Sharing Center → Change advanced sharing settingsHere you need to enable network discovery and file and printer sharing for the current profile.

Pay special attention to security settings. At the bottom of the sharing settings window, find the "All Networks" section. We recommend disabling password-protected sharing here if you trust all devices on your home network. This will prevent you from being constantly prompted for your username and password when connecting.

You can check visibility through File Explorer. Open "This PC" and go to "Network." If the setup was successful, you should see the second computer's name or at least the media device icon.

Organizing shared access to folders

Once the devices have "seen" each other, you need to grant them read and write permissions. Select the folder you want to share, right-click it, and select "Properties." Go to the "Access" tab and click "Advanced Settings."

In the window that opens, check the box next to "Share this folder." Click the "Permissions" button to fine-tune the permissions. Here, you can select a specific user or the "Everyone" group and grant them full access, edit access, or read-only access.

There's also a quicker way via the "Sharing" tab (without the word "advanced"). Select "Everyone" from the list, click "Add," and set the permission level. This method is simpler, but provides less control over individual users.

It's important to understand the difference between NTFS permissions and shared permissions. If access is allowed on one system but denied on the other (at the file system level), the user will be unable to log in. SMB protocol always applies the more restrictive of the two levels.

To access a shared folder from another computer, open File Explorer and enter in the address bar \\Computer_Name or IP addressIf everything is done correctly, a list of available resources will be displayed.

Using IP addresses for direct connection

Sometimes the DNS system malfunctions, and computers can't be located by name. In this case, the most reliable way to connect two PCs via Wi-Fi is to use static or well-known IP addresses. This eliminates name resolution errors.

You can find out your IP address through the command line. Click Win + R, enter cmd and press Enter. In the black window, enter the command ipconfig and find the line "IPv4 address". It usually looks like this 192.168.1.X or 192.168.0.X.

ipconfig

Write down the address of the first computer. On the second computer, click Win + R, enter \\192.168.1.X (substituting the actual address) and press Enter. This method often works even when the network environment is silent.

If the addresses are dynamic and constantly change after a router reboot, it makes sense to lock them. This can be done in the router settings (DHCP Reservation section) or manually in the TCP/IP adapter properties of the Windows server by entering a static IP address.

When manually assigning IP addresses, make sure they are in the same subnet as the router. If the gateway is on the router 192.168.0.1, then computers need to be given addresses of the form 192.168.0.X.

Solving visibility and access issues

Even with proper configuration, conflicts can still occur. A common issue is an access error or a password requirement you didn't set. This is due to Windows security policies, which override sharing settings.

Try enabling SMB 1.0 support if one of the computers is very old (Windows XP or old NAS). However, Using SMB 1.0 reduces overall network security, so turn it on only when absolutely necessary and only during data transfer.

Another important point is services. Make sure the "Function Discovery Resource Publication" service is running and set to "Automatic." Without it, the computer may not appear in the network neighborhood, even if IP access is enabled.

⚠️ Note: Third-party antivirus programs (Kaspersky, ESET, Avast) often have their own built-in firewalls. If standard methods don't work, temporarily disable network protection in your antivirus to test.

It's also worth checking that NetBIOS over TCP/IP is working. In the IPv4 adapter properties, under Advanced Settings, on the WINS tab, select "Enable NetBIOS over TCP/IP." This helps in mixed networks with different versions of Windows.

What should I do if it says "No access"?

Often, the problem lies in the credentials. Try creating an identical user with the same name and password on both computers. Windows often blocks anonymous access, but will allow "itself" access.

If nothing helps, reset your network settings. In Windows 10/11, this can be done via Settings → Network & Internet → Advanced network settings → Network resetThis will reset all network components to factory defaults.

Alternative methods and utilities

If Windows' built-in tools seem too cumbersome, there are third-party solutions that can make the task easier. Programs like Resilio Sync, SyncTrayzor or Dukto create their own tunnels and do not require complex configuration of access rights and group policies.

Gamers often face the challenge of connecting two PCs via Wi-Fi for local network gaming. This often requires not just sharing a folder, but creating a virtual adapter. Hamachi or Radmin VPN emulate a LAN cable over the Internet, allowing you to play together even if you're in different cities.

You can also use an FTP server. Installing a simple server (such as FileZilla Server) on one PC turns it into a file storage service accessible from any device on the network via a standard file transfer protocol.

• 🚀 Resilio Sync: Automatic folder synchronization in real time.
• 🎮 Hamachi: Ideal for older games that do not support online mode.
• 📂 FTP Server: A professional approach to transferring large files with logging.

The choice of method depends on the frequency of use. For a one-time file transfer, File Explorer is sufficient, but for continuous use, it's better to set up a static IP or use specialized software.

Frequently Asked Questions (FAQ)

Is it possible to connect two PCs via Wi-Fi without a router?

Yes, it's possible. Windows 10 and 11 have a feature called "Mobile Hotspot," which allows one computer to share Wi-Fi while another connects. You can also create a computer-to-computer (Ad-hoc) network, although this is more difficult to do in newer versions of Windows than in XP or 7.

Why can't computers see each other even though they have the same Wi-Fi?

Most likely, you have the "Public" network profile enabled. In this mode, Windows blocks discovery. Also, check if AP Isolation is enabled in your router settings.

What is the maximum transfer speed for Wi-Fi?

Speed ​​depends on the Wi-Fi standard. For 802.11n (Wi-Fi 4), the actual speed is around 40-50 Mbps. For 802.11ac (Wi-Fi 5), it's up to 400-500 Mbps under ideal conditions. Wi-Fi 6 (802.11ax) can reach gigabit speeds, but depends on signal strength.

Do both PCs need the same Wi-Fi password?

Yes, both devices must be connected to the same access point (SSID) with the correct security key. If one is connected to a guest network and the other to the main network, they can be separated by router settings.

Is it safe to disable password protection on a local network?

On a home network where no one else is present, this is safe and convenient. However, if neighbors or unauthorized individuals can connect to your Wi-Fi, they will have access to your files. It's recommended to use a strong password on your Wi-Fi connection.
