Modern homes are overflowing with digital devices, and there's often a pressing need to quickly transfer photos from one laptop to another or watch a movie on a TV directly from the computer's hard drive. In these situations, using flash drives seems archaic, and uploading files to the cloud takes too long, especially if your internet connection is slow. The optimal solution is to create a local network via Wi-Fi, which allows you to exchange data at the maximum speed your router can offer.
operating system Windows 10 provides powerful built-in collaboration tools, but hidden security settings and confusing settings menus often baffle users. Many simply don't know where to activate device discovery or how to properly configure access rights so that folders are visible but system files remain protected. In this article, we'll cover all the nuances of setting up local data exchange without the need for unnecessary wires.
You don't need specialized software or complex network utilities to get started. All the necessary components are already built into the system and are ready to use after proper configuration. The main thing is to ensure that all devices involved in file sharing are connected to the same wireless network. Wi-Fi, since data transfer between different subnets or guest zones of the router is blocked by default by routing rules.
Checking network settings and connection profile
The first and most critical step is to correctly identify the network type in the operating system itself. By default, Windows 10 considers any new connections potentially dangerous and applies a strict "Public Network" profile, which hides your computer from other devices. You must manually change this status to "Private Network" to allow the system to open ports for local communication.
To do this, go to the Network and Sharing Center by right-clicking the Wi-Fi icon in the system tray and selecting "Network & Internet Settings." In the window that opens, find the name of your current connection and click it. In the "Network Profile" section, switch the radio to "Private." This signals to the system that you are in a trusted environment, such as your home or office.
After changing the profile, the system will automatically apply the new set of firewall rules. Your computer will no longer be "invisible" to your wireless network neighbors. If you don't do this, any subsequent sharing settings will be useless, as the firewall will simply block incoming connection requests.
⚠️ Caution: When switching to a private network, make sure you're actually connected to a trusted Wi-Fi router. In public places (cafes, airports), leaving the "Private" profile is dangerous, as it makes your PC visible to attackers on the same network.
Enabling discovery and sharing features
After setting up your network profile, you need to enable the appropriate services in the advanced sharing options. These settings control how your computer responds to requests from other devices and whether it can initiate connections. Without these options enabled, even if you share a folder, other users simply won't see your PC in the list of network devices.
Open the Control Panel, go to Network and Internet, then Network and Sharing Center. In the left menu, select Change advanced sharing settings. Here you'll see several profiles (Private, Guest or Public, All Networks). The one you want is the "Private" profile.
Within this section, do the following:
- 📡 Turn on network discovery to let other computers see your device.
- 📂 Turn on file and printer sharing to allow data transfer.
- 🔓 Allow Windows to manage HomeGroup connections (if this feature is still supported by your system version).
It's also important to check the "All Networks" section at the bottom of the same window. Here, we recommend enabling sharing so that anyone on the network can access files, and optionally disabling password-protected sharing if you want to simplify connecting devices without having to enter credentials each time. However, for security, it's best to leave password protection enabled.
Setting access rights to a specific folder
Once the network infrastructure is ready, you can select the resources you want to share. Windows' mechanism allows you to share individual directories without opening access to the entire drive. This provides a balance between convenience and data security.
Select the folder you plan to share. Right-click it and select "Properties." Go to the "Sharing" tab and click "Advanced." Check the "Share this folder" box. The "Concurrent users" field usually has a limit, but for home use, you can leave it as is.
Next, you need to configure user permissions. Click the "Permissions" button. By default, it may be the "Everyone" group, but permissions are often limited to reading only. If you want other devices to be able to not only copy files but also write new ones or delete old ones, select the "Everyone" group and check the boxes for "Full Control," "Modify," and "Read" in the bottom window.
Don't forget to also go to the "Security" tab in the folder properties. Sometimes NTFS file system permissions block access even if the network settings are correct. Add the "Everyone" user (or a specific user) to the list and grant them "Modify" and "Write" permissions.
Connecting to shared resources from another device
Once a folder is shared, it can be found from another computer, laptop, or even a smartphone connected to the same Wi-Fi network. The resource search process in Windows 10 is standardized, but requires knowledge of the host computer's name or IP address.
Open File Explorer and enter two backslashes followed by the computer name or IP address in the address bar. The command format is:
\\ComputerNameor
\\192.168.1.55You can find the computer name in the system settings ("About") or on the "Properties" tab of the computer itself in File Explorer. The IP address is more convenient to use if computer names are not resolved by the router's DNS service. After entering the address and pressing Enter, the system will attempt to establish a connection.
If everything is configured correctly, you will see a list of all shared folders. The first time you connect, the system may ask for a username and password. You will need to enter the credentials of the computer where the folder is located (your Windows 10 username and password). If you disabled password protection, you will be logged in automatically.

Solving visibility and access issues
Despite this apparent simplicity, users often encounter a situation where computers fail to see each other on the network despite the correct settings. One common cause is a disabled discovery service or issues with the SMB protocol.
In Windows 10, the SMB 1.0 client may be disabled by default, which is necessary for working with older devices (for example, TVs). Samsung or LG (Old years), but for communication between modern PCs, this is rarely a problem. Most often, the problem lies with the Function Discovery Resource Publishing service. Make sure it's running. Click Win + R, enter services.msc and find "Function Discovery Resource Publishing" in the list. The startup type should be "Automatic" and the status should be "Running."
It's also worth checking your Windows Defender Firewall settings. Sometimes third-party antivirus programs can block local connections. Try temporarily disabling your antivirus for diagnostics. If the problem resolves, add an exception rule for the private network in your security software settings.
| Problem | Possible cause | Solution method |
|---|---|---|
| The computer is not visible on the network | Invalid network profile | Switch your profile to "Private" |
| Password prompt upon login | Password protection is enabled | Enter host account details or disable protection |
| Access error "No rights" | NTFS limitations | Add permissions in the Security tab |
| The TV doesn't see the PC | SMB 1.0 is disabled | Enable SMB 1.0 support in Windows components |
⚠️ Note: The Windows Settings interface may vary slightly depending on your build version (Home, Pro, Enterprise) and system updates. If you can't find the item, try searching for a keyword in Settings, such as "general."
Using an IP address for direct connection
Sometimes automatic computer name discovery on a local network is unstable due to router or DNS configuration issues. In such cases, the most reliable method is to use a static IP address or reserve an address in the router for the host computer.
Find out your computer's current IP address. To do this, open the command prompt (press Win + R, enter cmd) and run the command:
ipconfigFind the "IPv4 Address" line in the section for your wireless adapter. Write down these numbers. Now, use this address to connect from another device. The advantage of this method is that it works even when the network environment is silent.
For convenience, you can map a network share to a drive letter. In File Explorer, click "This PC," then select "Computer" → "Map Network Drive" from the top menu. Select any available drive letter (e.g., Z:) and enter the path in the "Folder" field: \\192.168.1.55\SharedFolderCheck the "Restore at logon" box. The folder will now be accessible as a regular drive in "My Computer."
Why does the connection to the network folder sometimes disappear?
To save power, Windows may turn off your Wi-Fi adapter or put your computer into sleep mode, which interrupts the connection. To avoid this, open Device Manager, locate your Wi-Fi adapter, open Properties → Power Management, and uncheck "Allow the computer to turn off this device to save power."
Security when organizing public access
When sharing files over Wi-Fi, you must be aware of the risks. If an outsider connects to your wireless network (for example, by hacking your Wi-Fi password), they could potentially gain access to your shared resources. Therefore, protecting your network perimeter is a top priority.
Use strong passwords on your Wi-Fi router and WPA2/WPA3 encryption. Never use open networks without a password to access shared files. It's also recommended to regularly update Windows user account passwords. If you grant access to guests, create a separate account with limited privileges for them to prevent them from accidentally or intentionally damaging system files.
It's important to understand that sharing is a two-way process. If you're connecting to someone else's folder, be careful with executable files. A local network isn't better protected from viruses than the internet. An antivirus program should be active and scan files in real time, even if the source is "inside" your home.
Frequently Asked Questions (FAQ)
Why is my computer not visible on the network even though all the settings are correct?
Most often, the problem lies with the "Discovery Provider Host" or "Function Discovery Resource Publishing" services. Check their status in services.msc. Also, make sure your antivirus software isn't set to "Public Network" for your current Wi-Fi connection.
Is it possible to share a folder with Mac or Linux users?
Yes, Windows uses the SMB protocol, which is supported by macOS and most Linux distributions by default. On a Mac, in Finder, select "Go" → "Connect to Server" and enter the address of your Windows PC. On Linux, use a file manager (Nautilus, Dolphin) and the "Connect to Server" feature.
How do I turn off sharing if I no longer need it?
Return to "Network and Sharing Center" → "Change advanced sharing settings." Under "All Networks," select "Turn off sharing." You can also block access to a specific folder by going to its properties on the "Sharing" tab and unchecking "Share with others."
Does Wi-Fi speed affect file copy speed?
Absolutely. Data transfer speeds on a local network are limited by the bandwidth of the slowest link. If you have a router with a 2.4 GHz band, your speed is unlikely to exceed 30-40 MB/s. For fast transfers of large files (4K video, disk images), we recommend using the 5 GHz band or a wired Gigabit Ethernet connection.
