Modern users rarely limit themselves to a single device, often working on multiple computers within the same apartment or office. The need to quickly transfer a file, run a heavy application on a powerful machine, or simply help a relative with system setup arises constantly. Wireless technology WiFi Allows you to organize full interaction between devices without unnecessary wires, turning the chaos of cables into an elegant digital ecosystem.
To successfully implement this task, it's important to understand the basic principles of building a local network. Computers must be in a unified information space, which is ensured by properly configured routers and operating systems. In this article, we'll cover in detail how to connect to another PC via WiFi using built-in Windows tools and third-party utilities.
The setup process may seem complicated at first glance, but following the steps consistently guarantees results. We'll cover methods applicable to modern operating systems, with a special focus on security. After all, an open network is a risk that must be mitigated through proper configuration.
Preparation of network infrastructure and equipment
The first and most important step is ensuring physical connectivity. Both computers must be connected to the same access point. WiFiIt doesn't matter whether you're using a home router or a corporate network, the main thing is that the devices' IP addresses are on the same subnet. If one computer is connected via cable and the other via wireless, this is also acceptable, provided the router doesn't isolate the clients from each other.
The second critical point is the network profile type. Windows treats new connections as public by default, which prevents others from seeing your device. You need to change the network profile to "Private" or "Home." This signal to the system that you trust the environment and allow data exchange. Without this step, further settings will be useless, as the firewall will simply reject incoming requests.
It's also worth checking the status of your network adapters. Make sure the drivers are WiFi The modules are updated and working correctly. An unstable signal or outdated software can cause connection interruptions at the most inopportune moments. To check, you can use the command line and a simple command. ping, which we will talk about later.
⚠️ Attention: If you are on a private network (cafe, airport), the PC detection function may be blocked at the hardware level by your ISP or network administrator for security reasons.
Setting up sharing options in Windows
Once the network connection is established, you need to enable the appropriate permissions in the operating system. In Windows 10 and 11, these settings are located in the Network and Sharing Center. Go to Control Panel and find the section responsible for changing sharing settings. This is the key to connecting to another PC via WiFi without errors.
In the window that opens, you'll see several profiles: private, guest, and all networks. For our purposes, the private profile is the one that's important. Network discovery must be enabled in it so other computers can see your PC. File and printer sharing should also be enabled. These actions will open the necessary ports in the system firewall.
Pay special attention to the "All Networks" section. This section contains an important option related to password protection. If you're in a trusted home environment, you can disable password-protected access to simplify login. However, in an office or when other people are present, it's best to leave this feature enabled to ensure that only authorized users with the correct credentials have access to resources.
☑️ Check network settings
After making changes, the system may require a reboot or simply apply the settings automatically. Check that other computers appear in the list of network devices in File Explorer. If they don't, try refreshing the list or restarting the discovery service.
Establishing access via remote desktop (RDP)
The most powerful tool for complete control of a computer is the protocol RDP (Remote Desktop Protocol). It allows you to not just view files, but also fully control the desktop of a remote machine, launch programs, and work as if you were sitting right in front of it. This feature is built into Windows, but requires activation on the receiving end.
To enable connections, go to System Settings, then the "Remote Desktop" section. Toggle the slider to "On." You'll also see the computer name you'll need to connect.
To initiate a connection on the second computer, use the built-in Remote Desktop Connection app. Enter the computer name or IP address. The system will prompt you for the remote PC's username and password. Make sure the user has remote login rights, otherwise access will be denied.
mstsc /v:192.168.1.55This command can be entered in the Run menu (Win + R) to immediately open a connection window to a specific address. This speeds up the process if you frequently work with the same machines.
Why isn't RDP working?
If the connection fails, check to see if the remote computer is asleep. RDP can't wake a computer from hibernation without special BIOS and network card settings (Wake-on-LAN). Also, make sure port 3389 isn't blocked by your antivirus software.
Using third-party programs for remote control
Built-in Windows tools are great, but sometimes they require complex configuration, especially if the computers are on different networks (for example, you're at home and your office PC is on the other side of town). In such cases, specialized programs that work over the internet but use the local network can help. WiFi channel for data transmission if the devices are nearby.
Popular solutions like TeamViewer, AnyDesk or RustDesk These tools significantly simplify the process. You don't need to know IP addresses or configure router ports. Simply install the program on both devices and enter the automatically generated ID and password. These utilities are often faster and more stable than standard RDP over the internet.
The advantage of such programs is their versatility. They allow you to transfer files, chat, record sessions, and even reboot your computer in safe mode to continue working. For one-time connections or helping relatives, this is an ideal option that doesn't require extensive technical knowledge.
| Program | License | Complexity | Speed of work |
|---|---|---|---|
| TeamViewer | Paid / Free | Low | High |
| AnyDesk | Paid / Free | Low | Very high |
| RustDesk | Open Source | Average | High |
| Chrome Remote | Free | Low | Average |
When choosing software, focus on your needs. Paid versions with centralized management are better for ongoing fleet management, while free alternatives are sufficient for personal use.
Advanced file sharing settings
If you don't need full screen control but just want to share documents, photos, or videos, it's more convenient to use shared folders. This allows you to work with files on the remote PC as if they were local, copying and editing them directly. To do this, create a folder, right-click it, and select "Properties."
In the Properties window, go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box. You can also configure permissions here: read-only access or full control, allowing you to modify and delete files. This is an important aspect. securityto prevent important system files from being accidentally deleted.
To access the shared folder, open File Explorer on the second computer. In the address bar, enter \\ComputerName or IP addressIf the settings are correct, you'll see a list of available resources. For convenience, you can right-click the folder and select "Mount as network drive," assigning it a letter (e.g., Z:). It will now appear in "My Computer" as a regular hard drive partition.
⚠️ Important: When disabling password protection, remember that anyone who connects to your WiFi will be able to access shared folders. Use strong passwords for your WiFi network.
Diagnosing problems and troubleshooting connection errors
Even with proper configuration, situations may arise where computers cannot see each other. First, check visibility using the command pingOpen the command prompt (cmd) and enter ping [IP address of remote PC]If you see a response with a response time (for example, time=2ms), then there is a physical connection and the problem is in the Windows settings.
If there's no ping, check whether your antivirus or firewall is blocking the connection. Third-party security suites often create their own security perimeter, ignoring Windows settings. Try temporarily disabling your antivirus to check. Also, make sure that services are running. Function Discovery Resource Publication And SSDP Discovery launched and operate in automatic mode.
Another common issue is different versions of the SMB protocol. Older systems (Windows XP, 7) and newer ones (Windows 10, 11) may have different encryption standards. If you're connecting an older PC to a new one, you may need to enable SMB 1.0 support in Windows components, although this reduces the overall level of network security.
Keep in mind that routers with AP Isolation can prevent communication between devices within the network. This feature is often enabled on guest networks at hotels or cafes, but it can also be accidentally enabled at home. Check the wireless settings in your router's interface.
Questions and Answers (FAQ)
Is it possible to connect to a turned off computer via WiFi?
Typically, no, since the network adapter is inactive when the PC is turned off. However, Wake-on-LAN (WoL) technology allows you to send a special magic packet to turn on the computer. This requires the PC to be connected to a power source, and WoL must be enabled in the BIOS and network card settings.
Why does the current session on the remote PC get reset when connecting via RDP?
This is the default behavior for Windows client versions (Home, Pro). The system supports only one active user session at a time. When a second user connects, the first is forcibly locked. Multiple simultaneous users require server versions of the OS or special patches.
Is it safe to use remote access over public WiFi?
Using public networks to transmit sensitive data is risky. It is recommended to use a VPN connection before starting a remote access session. This will create a secure tunnel and encrypt all traffic, protecting your logins and passwords from interception.
How do I find out the IP address of the computer I want to connect to?
On the target computer, open a command prompt and enter the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter. This is the address you need (usually looks like 192.168.xx).
Is it possible to control a computer from Android or iOS via WiFi?
Yes, it's possible. For Windows, there are apps like Microsoft Remote Desktop (official), TeamViewer, AnyDesk, and others. These apps allow you to control your PC desktop using your smartphone or tablet's touchscreen as a touchpad.
