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

Creating a local network between two computers is one of the most practical tasks for a modern user, allowing you to instantly exchange large files, play online games, or even share a printer without unnecessary wires. In the era of cloud storage and instant messaging, direct Wi-Fi Direct or a local area network (LAN) are often the only way to quickly transfer gigabytes of video or backup copies, regardless of internet speed and provider tariff restrictions.

The process of integrating two PCs into a single digital ecosystem seems complicated at first glance, but modern operating systems like Windows 10 and 11 already have built-in mechanisms for discovering nearby devices. You won't need to install a twisted pair cable or purchase additional equipment if both devices are within range of a single wireless router.

The main thing that will be required from you is to be careful when entering settings and to understand the logic behind how network profiles work. The key condition for a successful connection is that both computers are in the same subnet segment, that is, they must be connected to the same Wi-Fi router. In this article, we'll cover all the details, from basic setup to troubleshooting common errors that may arise during the process.

Checking basic requirements and preparing equipment

Before tackling complex settings in the control panel, you need to ensure that the physical connection is configured correctly. Both computers must be equipped with working Wi-Fi adapters, and their drivers must be up-to-date, as older software versions often don't support modern encryption standards or detection features.

Make sure both devices are connected to the same wireless network. This seems obvious, but a common mistake is connecting one PC to the router's main band (2.4 GHz) and the other to a guest network or 5 GHz band with isolated clients, making them invisible to each other.

It's also worth checking the network profile status. In Windows operating systems, new connections are classified as "Public" by default, which automatically hides your computer from other devices for security reasons. To establish a local connection, you need to change this status to "Private Network."

Please note the following critical points before starting the setup:

• 📡 Both computers are connected to the same router (the network SSID is the same).
• 🔋 On laptops, the Wi-Fi adapter's power-saving mode is disabled to prevent it from going to sleep.
• 🛡️ Antivirus software does not block local connections (temporarily disabling the firewall for testing often helps).
• 💻 The Network Discovery service is enabled on both PCs.

⚠️ Attention: If you're on a corporate network or dorm, administrators may have configured client isolation at the hardware level. In this case, connecting computers software-based won't work, even with ideal Windows settings.

Drivers are checked through the Device Manager. Click Win + X and select the appropriate menu item. Find the "Network Adapters" section, then locate your wireless module (usually the name includes the words "Wireless," "Wi-Fi," or "802.11"), or a brand name like Intel, Realtek, or Qualcomm. If the device icon has a yellow exclamation point, first install the drivers from the manufacturer's official website.

Setting up a network profile and discovery

The most important step, without which further actions are pointless, is switching the network profile. By default, Windows considers any new Wi-Fi connection potentially unsafe, so it hides your PC from prying eyes. To allow the connection, you need to tell the system that you are in a trusted environment, such as your home.

To change your profile in Windows 10 and 11, click the Wi-Fi icon in the system tray (near the clock) and select the properties of your current connection. In the window that opens, find the network type switch and set it to "Private." This automatically activates the necessary services for discovering devices and files.

After changing your profile, you need to enable sharing features. Open the Control Panel, go to "Network and Sharing Center," and select "Change advanced sharing settings" on the left. Here, expand the "Private" tab and enable the following options:

• 🔍 Enable network discovery.
• 📂 Enable file and printer sharing.
• 🏠 Allow Windows to manage HomeGroup connections (if available).

Don't forget to also scroll down to the "All Networks" section. Here, we recommend enabling sharing so that all network users can access shared folders, and, crucially, disabling password protection if you want to simplify login without entering credentials (though for security, it's best to leave it enabled and use the same logins and passwords on both PCs).

⚠️ Attention: The network settings interface in Windows 11 has been significantly redesigned. If you can't find the usual options, search for "Manage advanced sharing settings" in System Settings.

Organizing shared access to folders and disks

Once the computers have "seen" each other in the network, you need to grant permission to access specific data. You can share either a single folder or an entire drive, although the latter is not recommended for security reasons.

To configure this, select the folder you want to share. Right-click it and select "Properties." Go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box.

Next, you need to configure permissions. Click the "Permissions" button. By default, the "Everyone" group is set to read-only. If you want the second computer to be able to not only retrieve files but also write their own or delete old ones, check the "Full Control" box in the "Allow" column.

The nuances of NTFS access rights

Sharing permissions and NTFS security permissions are two different levels of protection. If permissions are allowed in one area and denied in another, the most restrictive permission takes precedence. For a home network, it's easiest to add the "Everyone" user to both tabs with full permissions.

There's also a quicker way via the "Sharing" tab (without the word "Advanced"). Click "Share," select "Everyone" from the drop-down list, and click "Add." You can select the access level right away: read or read and write. This method is simpler and more intuitive for beginners.

Now on the second computer, open File Explorer and enter in the address bar \\Name_of_the_First_Computer or IP address of the first computerIf everything is done correctly, you will see the shared folder and be able to work with the files as if they were local.

Using Shared Folders and Nearby Sharing

In modern versions of Windows (10 and 11), there's a more elegant way to transfer files that doesn't require complex permissions and network path configurations. This feature is called "Shared Folders" (formerly known as HomeGroup in older versions, but now implemented differently) or "Nearby Sharing."

To enable Nearby Sharing, open Settings (Win + I) and go to "System" -> "Shared Folders" (or "Nearby Sharing," depending on the localization version). Enable this feature on both computers. Now, when you try to open a file via the context menu or the "Share" button in a browser or app, you'll see the second computer's name in the list of available devices.

This method is ideal for quickly transferring photos, documents, or links. Files are transferred directly over Wi-Fi, bypassing the internet connection. Transfer speed depends on signal quality and supported standards (802.11n, ac, ax).

However, this method has a limitation: it's not suitable for creating a persistent network drive that's convenient for daily use. For ongoing use, it's better to use the classic method with network drive mapping.

Mapping a network drive for permanent operation

To avoid re-entering the network path each time and to ensure shared folders appear in "My Computer" as a separate drive (e.g., Z:), map a network drive. This will transform the remote storage into a fully-fledged part of your file system.

Open "This PC" in File Explorer. In the top menu, click "Computer" -> "Map network drive." Select any available drive letter from the list. In the "Folder" field, enter the path to the resource, for example: \\192.168.1.5\SharedFilesBe sure to check the box "Reconnect at logon."

If the system prompts you for credentials, enter the username and password for the user account on the computer where the folder is located. For convenience, you can check the "Remember credentials" box to avoid entering them each time you start your PC.

Now you have a new drive in File Explorer. All files you save to it will physically be on the other computer's hard drive, but you'll be able to access them as usual. This is a great way to free up space on your primary SSD using a second PC.

Troubleshooting and connection diagnostics

Even with proper configuration, errors may still occur. The most common is "Windows cannot access..." accompanied by an error code. Often, the problem lies with Windows services that have stopped for some reason.

Please check if the following services are running. Click Win + R, enter services.msc and find in the list:

• 🖥️ Function Discovery Resource Publication.
• 🔎 Function Discovery Provider Host.
• 📡 SSDP Discovery.
• 🌐 UPnP Device Host.

For each of these services, set the startup type to "Automatic" and click "Start" if they are stopped. The first service is especially critical—it's responsible for making your computer visible on the network.

⚠️ Attention: After a Windows update (especially major updates like 22H2 or the upgrade to 23H2), sharing settings may reset to factory defaults. If the network suddenly disappears, check your network profile again.

Clearing the DNS cache and resetting network settings also helps. Open the command prompt as administrator and enter the command ipconfig /flushdnsIf the problem persists, try temporarily disabling your antivirus software on both PCs, as third-party firewalls often block the SMB protocol used for file transfers.

Frequently Asked Questions (FAQ)

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

Yes, it's possible. You can create a direct computer-to-computer connection (Ad-Hoc network) or use the Mobile Hotspot feature in Windows 10/11. One PC shares the Wi-Fi, and the other connects to it as a regular access point. The speed will be slower than using a router, but you can still transfer files.

Why doesn't the second computer see the first one in the network environment?

Most often, the cause is the "Public" network profile or a disabled discovery service. Also, check that both PCs are in the same workgroup (usually WORKGROUP) and that the computer names are unique (they can't have the same name).

What is the maximum file transfer speed over Wi-Fi?

Speed ​​depends on the Wi-Fi standard. For 802.11n (Wi-Fi 4), the actual speed is around 20-40 Mbps. For 802.11ac (Wi-Fi 5), it's up to 100-400 Mbps under ideal conditions. For 802.11ax (Wi-Fi 6), speeds can exceed 500 Mbps, which is comparable to a gigabit cable.

Is it safe to keep sharing enabled all the time?

If you have the "Private Network" profile enabled and a strong password set for logging into Windows, the risk is minimal. However, in public places (cafes, airports), always switch to "Public Network" or disable public access to prevent hackers from accessing your data.

How do I find out the IP address of a computer to connect to?

Click Win + R, enter cmd and press Enter. In the black window, enter the command ipconfigFind the "IPv4 Address" line under your wireless adapter. This is the address you need to enter on the second computer.
