Creating a local network between devices is the foundation of the modern digital workspace, allowing for the instant exchange of large files without the need for external drives. Many users still transfer data to flash drives or send it via instant messaging apps, losing time and image quality due to automatic compression. Direct wireless connection WiFi solves the problem of speed and convenience, turning disparate gadgets into a single ecosystem.
The setup process may seem complicated at first glance, but modern operating systems such as Windows 10 And Windows 11, have built-in tools to simplify this process. You won't need to purchase additional equipment or install complex server solutions for basic document sharing within an apartment or small office. Simply configure access parameters correctly and ensure all devices are on the same network segment.
In this article, we'll detail the steps you need to take to establish a stable connection between your desktop computer, laptop, and even mobile devices. We'll also cover security issues to prevent your personal data from becoming accessible to third parties, and we'll also explore common mistakes users encounter when first starting out. The key to successful synchronization is that all devices belong to the same network profile, usually designated as “Private” or “Home”.
Preliminary check of network parameters
Before setting up sharing, you need to ensure that the physical connection between the devices is stable and correctly configured at the router level. All computers you plan to share must be connected to the same router, regardless of whether they use a wireless or cable connection. EthernetIf one device is connected to a guest network and the other to the main network, they will not "see" each other in the list of available nodes.
An important step is checking the network profile type, as the operating system may restrict your PC's visibility on public networks by default for security reasons. You should go to the network settings and change the profile from "Public" to "Private," which will allow the device to be discovered by other network members. Without this step, further manipulation of folders and printers will be pointless, as the firewall will block incoming requests.
It is also worth paying attention to the IP addresses of the devices: for stable operation, it is desirable that they are in the same subnet, which usually happens automatically when distributing addresses through DHCP router server. If you're using complex corporate settings or static IP addresses, make sure the subnet mask matches on all machines, otherwise data packets simply won't find their destination. You can check the current address from the command line by entering the command ipconfig and finding the IPv4 address line.
⚠️ Warning: If you are in a public place (cafe, airport), it is strongly recommended not to enable network discovery, as this will make your files visible to intruders using the same WiFi.
Setting up sharing in Windows
The central element of the configuration is the Network Control Panel, where global rules for communication between computers are set. To get started, open the Control Panel, go to the Network and Internet section, and then select Network and Sharing Center. On the left side of the window, find the link "Change advanced sharing settings," which will open the required settings menu.
In the window that opens, you'll see several profiles, including the currently active one, labeled "Private." Here, you need to enable the "Turn on network discovery" switch and check the "Turn on file and printer sharing" box. These actions tell the operating system that you trust surrounding devices and allow them to request access to your resources via the protocol. SMB.
☑️ Network setup checklist
The "All Networks" section deserves special attention, as it contains the "Password-protected sharing" setting. If you're in a completely secure home environment, you can disable this feature, allowing any device on the network to access shared folders without entering a username and password. However, if you have children or guests on your network, it's best to leave this feature enabled to control who exactly has access to your data using their accounts. Windows.
Creating and sharing folders
Once the foundation is laid, you can move on to organizing the storage space for shared files. Select the directory on your hard drive you want to make accessible to other users and right-click it. Select "Properties" from the context menu, then go to the "Sharing" tab, where you'll find permissions management tools.
Click the "Advanced Settings" button and check the "Share this folder" box. In the "Share Name" field, you can accept the system-suggested name or enter a more descriptive one that will be visible to other network users. Next, click the "Permissions" button to determine what actions remote users can perform: read-only files, modify existing files, or full control over the contents.
| Permission type | Description of action | Recommended use |
|---|---|---|
| Full access | Reading, writing, modifying, and deleting files | For trusted users only |
| Change | Read, write, and delete, but without changing access rights | For colleagues or family members |
| Reading | View and copy files only | For media libraries and archives |
There's also a quicker method called "Sharing," which is accessible directly from the folder's context menu. This method is simpler, but offers less flexibility in setting access rights for specific users, assigning a default set of permissions to the "Everyone" group. For most home tasks, this is sufficient, but for setting up a file server, it's better to use the advanced settings via the "Security" tab.
⚠️ Note: Granting "Full Control" permissions to the "Everyone" group means that anyone who connects to your WiFi will be able to delete your files unless a password is set to log in.
Connecting to network resources
Once the folder is ready for use, the question arises of how to access it from another computer. The easiest way is to open File Explorer and go to the "Network" section in the left navigation panel. If network discovery is configured correctly, you'll see the names of all available computers on the local network. Double-clicking any of them will open a list of shared resources.
If your computer doesn't show up automatically, you can use a direct path using its IP address or hostname. Press the key combination Win + R, in the Run window that appears, enter two backslashes and the IP address of the target computer, for example: \\192.168.1.5 or \\ComputerNameThis method is often faster and more reliable, especially if detection services are experiencing delays.
What should I do if it asks for a password?
If the system requires credentials upon login, enter the username and password for the user account on the computer where the folder is located. If the account doesn't have a password, Windows may be blocking access based on security policies. In this case, create a password for the user or disable the password requirement in the registry (not recommended for beginners).
For easy, permanent use, you can map a network folder as a separate drive in the system. In the Explorer window with the network share open, right-click the desired folder and select "Map network drive." Select an available drive letter from the list, and from now on, the shared folder will appear in "My Computer" along with local partitions. C: And D:.
Real-time synchronization and cloud solutions
Classic file sharing is good for storage, but if you really need syncing—that is, automatically updating files across all devices whenever they change—it's worth considering specialized tools. The built-in Near Share feature in Windows 10/11 allows for quick file transfers via Bluetooth and WiFi, but it doesn't provide background folder syncing.
For full synchronization without the volume and speed limitations typical of cloud services, you can use programs based on P2P technology, such as Resilio Sync or SyncthingThese apps create a direct connection between computers via WiFi and synchronize specified folders in real time without uploading data to third-party servers, ensuring high speed and privacy.
An alternative is cloud storage with a local network function, for example, Dropbox LAN sync or settings OneDriveThey allow computers on the same network to exchange files directly, bypassing the internet, significantly speeding up the initial download of large amounts of data. The choice of method depends on your needs: one-time transfer, ongoing access, or data mirroring.
Diagnostics and troubleshooting
Despite the apparent simplicity, users often encounter situations where computers cannot see each other or access is denied. One of the most common causes is the Discovery Resource Publishing service, which may be disabled by default in Windows. To fix this, click Win + R, enter services.msc, find the "Function Discovery Resource Publication" service and set the startup type to "Automatic", then restart it.
Another common issue is connection blocking by antivirus or firewall software. If you're confident your network is secure, try temporarily disabling your third-party antivirus software to test it. If the issue resolves, you'll need to add an exception to the firewall settings for "File and Printer Sharing" in the private network profile.
- 🔍 Error "Access Denied": Check if the account passwords on both PCs match if password protection is enabled.
- 📡 Computer is not visible: Make sure the DNS service is working correctly, or use the IP address instead of the name.
- 🔒 Password request: Try entering your login in the format
PCName\Userso that the system understands which account to access.
In some cases, resetting network settings via the command line can help. Launch Terminal as administrator and run the command netsh winsock reset, and then restart your computer. This action clears the network socket cache and often resolves connection issues caused by software protocol glitches. TCP/IP.
⚠️ Note: Windows settings interfaces may vary slightly depending on the update version (21H2, 22H2, etc.). If you can't find the item, search for keywords in the system settings.
Questions and Answers (FAQ)
Is it possible to sync computers via WiFi without a router?
Yes, this is possible by creating a wireless ad-hoc network or using the Mobile Hotspot feature in Windows 10/11. One computer distributes the WiFi, which the second computer connects to, and then the sharing setup procedure remains the same.
Why is file transfer speed via WiFi lower than via cable?
Wireless connections are subject to interference from other devices, distance, and obstacles (such as walls), which reduces actual throughput. Furthermore, WiFi operates in half-duplex mode, while Ethernet cables provide more stable and faster data transfer.
Is it safe to keep sharing enabled all the time?
If you're on a home network with a strong WiFi password and complex passwords for your Windows accounts, the risks are minimal. However, on public networks or in offices with guest access, it's recommended to disable sharing when not in use.
How do I find out the IP address of a computer to connect to?
Open command prompt (cmd), enter the command ipconfig and find the IPv4 address line. You can also find the address in the network connection properties in Windows settings.
