Organizing a local network between two or more computers often becomes necessary for quickly transferring large amounts of data without using external storage devices. Local file sharing Using a Wi-Fi router eliminates the need to connect flash drives or external hard drives, saving time and maintaining speed. Windows 10 This process is standardized, but requires careful configuration of security and network discovery settings.
Many users encounter difficulties when trying to open access to the disk, since modern security protocols block external connections by default. SMB network protocolThe app used for sharing must be configured correctly on both devices. If you want to create a centralized repository for documents or media files accessible from any laptop in the apartment, you'll need to complete a series of steps in the control panel.
Before you begin setting up access rights, make sure both computers are connected to the same wireless network. Router The shared folder must correctly distribute IP addresses so that devices can "see" each other in the list of available devices. In this article, we'll walk through each step of creating a shared folder, eliminating common errors that often lead to access denial.
Checking network connection parameters
The first step is to verify the network type that the system has assigned to your Wi-Fi connection. Network profile This should be set to "Private," as "Public" mode hides your computer from other devices for security purposes. If you're at home or in an office where you trust other users, switching to a private profile is essential.
To change your network type, open System Settings from the Start menu and select "Network & Internet." In the connection status window, click the name of your Wi-Fi connection and select "Private." Network discovery is activated automatically only after this procedure, allowing computers to exchange service data packets.
It's also worth making sure both computers are in the same workgroup, although in modern versions of Windows this is less likely to cause problems than the profile type. IP addresses The devices must be on the same subnet, for example, 192.168.0.x and 192.168.0.y. You can check the current status through the command line by entering the command ipconfig.
If computers are connected to a guest Wi-Fi network, client isolation may interfere with the connection. In this case, you should access your router settings and disable access point isolation if it is enabled.
Setting up sharing in Control Panel
Basic sharing settings are configured through the advanced network management menu. Open the Control Panel, go to Network and Internet, and select Network and Sharing Center. On the left side of the window, find the link "Change advanced sharing settings."
In the window that opens, you'll see profiles for different network types. Make sure you're in the "Private (current profile)" section. Here, you need to enable the following options: "Turn on network discovery" and "Turn on file and printer sharing." Automatic configuration connected network devices should also be enabled to simplify the process.
At the bottom of the window, under the "All Networks" section, we recommend enabling password-protected sharing if you want to control who exactly has access to your data. Password protection requires entering the credentials of the user who created the folder when connecting from another computer.
⚠️ Warning: If you disable password protection, anyone who connects to your Wi-Fi network will be able to access shared files without authorization.
After making all changes, be sure to click "Save Changes" for the new configuration profile to take effect. Restarting network services is usually not necessary, but reconnecting to Wi-Fi may be necessary.
Creating and sharing a folder
Once your network environment is ready, you can begin creating a resource that will be accessible to other users. Create a new folder in a convenient location, such as on a disk. D: or in the root of the disk C:, and give it a descriptive name, such as ShareData.
Right-click the created folder and select "Properties." Go to the "Sharing" tab and click "Advanced." In the window that opens, check the "Share this folder" box.
To manage user rights, click the "Permissions" button. Here you can add a specific user or the "Everyone" group and set access levels: "Full Control," "Modify," or "Read." Access rights determine whether the remote user can only view files or also edit and delete them.
☑️ Access Permissions Setup Checklist
It's also important to check the "Security" tab in the folder's properties. If the "Everyone" user or a specific user who requires access is missing from the list of group objects, the system may block the connection even if the "Access" tab settings are correct. Add the required user and ensure they have read and execute permissions.
Connecting to a shared folder from another computer
Now let's move on to the second computer that needs to access the data. Open File Explorer and enter the IP address of the first computer in the address bar in the format \\192.168.0.X, where X is the last part of the first PC's address. Alternatively, you can use the computer name if it is known and resolved by DNS.
The first time you connect, the system may ask for credentials. Enter the username and password of the user on the first computer that owns the folder. Accounts must match those registered on the host, otherwise access will be denied by security policies.
If the connection is successful, you will see the contents of the shared folder. For ease of use, you can right-click the folder and select "Map network drive." This will allow the system to assign a drive letter to the folder (e.g., Z:), and it will appear in My Computer as a local partition.
⚠️ Note: If you change the account password on the primary computer, the saved credentials on the client PC will no longer work and access will be lost until the password is updated in the Credential Manager.
To automatically connect every time the system starts, make sure that the "Reconnect at logon" box is checked in the network drive mapping window.
Solving common access problems and errors
One of the most common issues is the error "Windows cannot access...." This is often due to disabled services or blocked ports by a firewall. Check if the service is running. Workstation And Function Discovery Resource Publication in the services menu (services.msc).
Another common cause of failures is a disabled SMB 1.0 protocol, which is required for older devices but is disabled by default in Windows 10 due to vulnerabilities. However, SMB 2/3 is usually sufficient for communication between modern PCs. If you have a mix of older and newer systems, you may need to enable SMB 1.0 support using "Turn Windows features on or off."
Windows Firewall may be blocking incoming connections. Make sure "File and Printer Sharing (SMB-In)" is allowed in your firewall rules. Firewall rules must be active for the "Private" and "Domain" profiles.
What to do if your computer is not visible on the network?
If your computer isn't visible in Network Neighborhood, try flushing the DNS cache with the ipconfig /flushdns command and rebooting the router. Also, check to see if your antivirus software is blocking network communication.
Sometimes simply restarting the discovery service helps. Open a command prompt as administrator and run the command net stop fdrespub, and then net start fdrespubThis will force the computer to re-register on the network.
Security and speed optimization
When setting up shared access, it's important to keep data security in mind. Use strong passwords for user accounts and avoid granting full access to the "Everyone" group if there are guest devices on the network. Data encryption When transferring data over a local network in Windows 10, it is ensured by SMB protocols, but the physical protection of the router is also important.
File transfer speed over Wi-Fi directly depends on the wireless standard and signal quality. If the router supports the range 5 GHzIt's recommended to connect both computers to this network to achieve maximum throughput. The 2.4 GHz band is often congested and offers lower speeds.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Network type | Private | Opens ports for discovery |
| Protocol | SMB 2/3 | Provides speed and security |
| Wi-Fi frequency | 5 GHz | Maximum transfer rate |
| Protection | Password | User access control |
For stable operation, it's recommended that both computers receive permanent IP addresses (static IP) or that address reservations be configured in the router's DHCP server. This will prevent situations where a computer's address changes after a router reboot, causing shortcuts to network drives to stop working.
Frequently Asked Questions (FAQ)
Is it possible to access a shared folder from a phone?
Yes, you can access a shared folder from Android or iOS smartphones. To do so, use a file manager that supports SMB (such as My Files or Documents) and enter the computer's IP address and Windows user credentials.
Why does access disappear after restarting the computer?
Most likely, the computer's IP address has changed, as it is assigned dynamically by the router. Solution: configure a static IP address in the network adapter properties or reserve an address in the router's DHCP settings.
Is it safe to keep a shared folder open all the time?
This is only safe within a trusted home network. If others can connect to your Wi-Fi, be sure to use a strong Wi-Fi password and enable password protection for shared folders.
How to remove a shared folder?
Go to the folder properties, click the "Sharing" tab, click "Advanced" and uncheck "Share this folder." This will make the folder accessible only locally.
