In today's digital world, the need to monitor multiple devices simultaneously is becoming increasingly common, whether on a home network or in a corporate office. Remote access to a neighboring computer on the same local Wi-Fi network allows administrators to resolve technical issues, and users to conveniently work with files without having to physically move. This is especially true when the target PC is located in another room or even in a neighboring office, but is connected to the same wireless access point.
There are many ways to implement this connection, from built-in system utilities to specialized third-party software. The choice of a specific method depends on the operating system, security requirements, and frequency of use. It's important to understand that for stable operation, both devices must be on the same subnet and have the correct network discovery settings.
In this article, we'll cover every setup step in detail, from basic router settings to using advanced remote desktop protocols. You'll learn how to avoid common connection errors and ensure maximum data transfer speeds between devices.
Basic network preparation and connection testing
The first and most important step is to ensure a stable connection between the managing and managed devices. Both computers should be connected to the same router, preferably at 5 GHz to reduce latency. If one device is using a wired connection and the other is using Wi-Fi, make sure client isolation isn't enabled on the router, which blocks data exchange between ports.
To get started, you need to find out the IP address of the target computer, as this is what will be used for network identification. This can be done via the command line by entering the command ipconfig and find the "IPv4 Address" line. Write down these numbers; you'll need them for further connection setup.
It's also worth checking the device's visibility on the network. If the computer is hidden from other users, no remote access programs will be able to connect to it. Make sure the network type in Windows is set to "Private" and not "Public," as the latter profile prevents discovery by default.
⚠️ Note: If you're in a public place (cafe, airport), local access methods may be blocked by your router's security settings. In such cases, use only secure cloud services.
The connection can be checked using the Ping utility. Open the command prompt on your PC and enter ping [neighbor's IP address]If you see responses indicating time in milliseconds, the physical connection is established correctly and you can proceed to software configuration.
Setting up Windows' built-in Remote Desktop
The Windows operating system has a powerful built-in tool called Remote Desktop Protocol (RDP), which allows you to stream images and send commands to a remote machine. However, it's important to remember that the host function is only available in the Pro and Enterprise editions, while the Home edition can only act as a client.
To enable this feature on the target computer, go to "Settings" → "System" → "Remote Desktop." Toggle the switch to "On." The system will automatically create an exception in the firewall, but if you're using third-party antivirus software, you may need to manually configure the rules.
Setting a password on the user account is critical. For security reasons, the RDP protocol often refuses to work with accounts that don't have password protection. If you use local login without a password, create one or edit the security policy using the Group Policy Editor.
☑️ Checking RDP settings
To connect from another device, launch the Remote Desktop Connection app and enter the IP address of the neighboring PC. After entering your credentials, you'll see the remote machine's desktop as your own, allowing you to run any programs and work with files.
Using third-party programs for remote access
If built-in Windows tools seem too complex or your operating system version doesn't support host mode, specialized utilities can help. Programs such as TeamViewer, AnyDesk or RustDesk They work over a local network and via the Internet, providing image forwarding even through complex NATs.
The advantage of such solutions is their cross-platform nature and the elimination of the need to configure router ports. Simply install the client on both computers. On a local network, these programs often automatically detect neighboring devices by ID or name, significantly speeding up the connection process.
Let's look at a comparison of popular solutions for local use:
| Program | LAN speed | Difficulty of setup | Home License |
|---|---|---|---|
| TeamViewer | High | Low | For free |
| AnyDesk | Very high | Low | For free |
| Chrome Remote Desktop | Average | Average | For free |
| RustDesk | High | Average | Open Source |
When using AnyDesk With similar devices on a local network, image transfer rates can reach 60 FPS, making work virtually indistinguishable from sitting at the computer itself. This is especially important for tasks that require high responsiveness, such as graphic design or video editing.
⚠️ Note: Free versions of commercial programs may limit session time or connection frequency if they suspect commercial use. For permanent access, consider purchasing a license or using open-source alternatives.
Sharing files and folders via SMB
Computer management often doesn't involve full control of the screen, but rather access to specific files or folders. The SMB (Server Message Block) protocol is a standard for data exchange in Windows networks and allows for sharing resources with other users.
To configure this feature, open File Explorer, right-click the desired folder, and select Properties → Sharing tab. Click the Advanced button and check the box next to "Share." You can also configure permissions here: read-only or full control with the ability to delete files.
To access a shared folder from a neighboring computer, open File Explorer and enter in the address bar \\Neighbor's IP address\The system will request the username and password for the folder owner's account. After successful authorization, the folder will open as a regular directory, and you can copy files.
For convenience, you can map a network folder as a separate drive. In File Explorer, click "This PC" → "Computer" → "Map Network Drive." Select the drive letter and specify the path to the resource. This will allow you to work with your neighbor's files as if they were local, opening documents directly in Word or Excel.
Solving the SMB password problem
If Windows requires a password and you want to sign in without one (only on a trusted home network), you can disable the password requirement. To do this, go to Network and Sharing Center → Change advanced sharing settings → Turn on password-protected sharing → Select "Disable."
Remote management via command line and PowerShell
For system administrators and advanced users, the graphical interface may be overkill. Command-line management (CMD) or PowerShell allows you to run scripts, reboot the system, launch processes, and collect information without transmitting a video stream, saving bandwidth.
The main tool here is the utility psexec from the Sysinternals toolkit or built-in PowerShell commands with .remoting support. For example, to run a program remotely, you can use the command: psexec \\IP_address -u User -p Password cmd /c "notepad.exe".
PowerShell Remoting requires pre-configuration via command Enable-PSRemoting -Force on the target machine. You can then create sessions in which commands are executed on the remote computer and the results are displayed on your screen.
Enter-PSSession -ComputerName 192.168.1.55 -Credential (Get-Credential)This method is ideal for mass maintenance of a fleet of computers, when you need to simultaneously update software or check the status of services on dozens of machines connected to the same Wi-Fi network.
Security issues and protection from unauthorized access
Open access to a computer via Wi-Fi carries serious risks if the network is unsecured. An attacker connected to your Wi-Fi network could theoretically attempt to brute-force the password to your remote desktop or shared folder.
Always use complex passwords for Windows accounts. Disable RDP version 1.0 and use only version 2.0 with Network Level Authentication (NLA) encryption. This requires user authentication before establishing a full session.
If you don't use remote access features regularly, keep them disabled. Enable services only when needed, and then disable them through Services (services.msc) or the firewall. This minimizes the attack surface.
It's also recommended to regularly update your router firmware. Manufacturers often patch vulnerabilities that could allow access from a local network to a global network, or vice versa. An old router can become a security hole in your entire home network.
Is it possible to control a computer via Wi-Fi without installing programs?
Yes, if both computers are running Windows Pro or higher, you can use the built-in Remote Desktop. File sharing via SMB is also available. Full control without third-party software is more difficult on Windows Home and requires registry editing or PowerShell.
Why does Remote Desktop disconnect when I log in as a local user?
Client versions of Windows (Home, Pro) support only one active session. If you connect remotely, the local user will be logged out. Concurrent use requires a server version of Windows or special patches/hacks (RDP Wrapper), which may violate the license agreement.
What Wi-Fi speed is needed for comfortable work?
A stable 10-20 Mbps connection is sufficient for working with documents and browsing. For watching high-definition video or working with graphics, a speed of 50-100 Mbps is recommended, along with the use of the 5 GHz band to reduce latency.
Is it safe to leave port 3389 open?
Opening the RDP port (3389) directly to the internet without a VPN is strongly discouraged. The risk is lower on a local Wi-Fi network, but only if your password is strong and the network is protected by WPA2/WPA3 encryption.
