Establishing a local connection between two devices without using cables is a task that often arises when you need to quickly transfer files or launch a game over the network. In the operating system Windows 10 This process has been modified compared to previous versions, making it more secure but also slightly more confusing for untrained users. The system now requires explicit confirmation of the desire to share content, preventing accidental sharing in public places.
To successfully integrate your devices into a single digital ecosystem, you will need to ensure that both devices are connected to the same wireless routerThis is a fundamental requirement; ignoring it will render all further configurations meaningless. If one laptop is connected via mobile data and the other via home Wi-Fi, they won't be able to see each other.
In this article, we'll cover all the nuances of configuring network profiles, setting up sharing options, and resolving common device visibility issues. You'll learn how to set them up correctly. firewall and manage folder permissions so that data is accessible only to you and not to all your neighbors.
Checking network parameters and names
The first step before starting setup is to make the device IDs readable. Windows 10 assigns random names to computers by default, like DESKTOP-4A5B6C7, which is extremely inconvenient for searching in your network environment. It would be more logical to rename them to "Kitchen-PC" or "Office-Laptop" so you can immediately identify which device you're connecting to.
To do this, open the system settings and find the "About" section. There's a rename button here; after using it, a reboot will be required. It's also crucial to check the IP addresses: they should be in the same subnet, for example, 192.168.1.5 and 192.168.1.12. If the addresses start with different numbers (for example, 192.168.0.x and 192.168.1.x), the router won't allow them to communicate directly without complex routing.
Make sure the network type is set to "Private." If the system considers your home network "Public," it will automatically hide your computer from detection by other devices for security purposes. You can switch profiles in the Wi-Fi settings by clicking on the properties of the connected network.
Setting up a network profile and discovery
The central element of the configuration is the network profile. It dictates the rules of conduct. operating system When connecting to a new access point. The private profile enables network discovery, allowing your PC to see and be visible to other devices. These features are blocked in the public profile.
To activate the desired mode, go to "Settings" → "Network & Internet" → "Status." Click the "Sharing options" link. Here you'll see three profiles: private, guest, or public, and all networks. We're interested in the first option, where you need to enable the "Turn on network discovery" switch and check the "Turn on automatic configuration of devices that connect to the network" box.
⚠️ Caution: Enabling network discovery on public Wi-Fi (such as cafes or airports) exposes your data to potential attacks from intruders on the same network. Always check your profile type before enabling these features.
Next, enable file and printer sharing. This permission allows other network users to access your PC's resources. Without this option enabled, even if your computer is visible, attempts to access folders will fail with an authorization error.
Configuring resource sharing
After enabling basic discovery, you need to configure which resources will be accessible. Windows 10 allows you to share specific folders or entire drives. To start working with shared folders, return to the Network and Sharing Center and select "Change advanced sharing settings."
In the "All Networks" section, you'll find an important setting called "Password-protected sharing." If you're on a trusted home network, you can disable this feature, allowing you to access your files without entering your username and password. However, if you have children or guests on the network, it's best to leave it enabled to control access.
☑️ Check access settings
To grant access to a specific folder, right-click it, select "Properties," and go to the "Sharing" tab. Click "Advanced Settings," check "Share," and set permissions for the "Everyone" group or a specific user. Permissions can be read-only or read-write, allowing remote editing.
Using Home Group and New Methods
It's worth noting that the classic "HomeGroup," popular in Windows 7, was deprecated in Windows 10 (starting with version 1803). Microsoft replaced it with simpler, but less functional, sharing methods. The focus now shifts to direct file transfers via the SMB protocol or cloud services.
To share files without setting up complex permissions, you can use Nearby Sharing. It works similarly to AirDrop on Apple devices. To use it, both computers must have AirDrop enabled. Bluetooth and Wi-Fi, and be signed in with Microsoft accounts.
⚠️ Please note: Nearby Share is only suitable for transferring individual, small files. It is not suitable for providing continuous access to your media library or game files.
If you need a full-fledged local network for gaming or database work, it's best to use the traditional folder sharing method described above. This ensures a stable connection and high data transfer speeds, independent of Microsoft services.
Solving computer visibility issues
A common situation: all the settings are correct, but the computers don't see each other in File Explorer. In 90% of cases, the problem lies with the feature detection support service or the firewall. Windows can block incoming connections, deeming them suspicious, even within a home network.
To diagnose the issue, try running the ping command. Open the command prompt (cmd) and enter the IP address of the second computer. If a response is received, then there is a physical connection and the problem lies with the software access settings. If the requests time out, check your router settings and AP Isolation, which prevents Wi-Fi devices from communicating with each other.
What is client isolation in a router?
Client Isolation (or AP Isolation) is a security feature in wireless access points that prevents wireless clients from accessing each other. It is typically enabled by default on public networks, but should be disabled in home environments for local area networks to function.
It's also worth checking Windows services. Click Win + R, enter services.msc and find the "Function Discovery Resource Publishing" service. Make sure it's running and the startup type is set to "Automatic." Without this service, the computer won't broadcast its capabilities to the network.
Mapping a network drive for convenience
To avoid searching for a shared folder over the Network, you can mount it as a separate drive in My Computer. This is especially convenient if you frequently work with files on another PC or media server. The system will treat the remote folder as part of your file system.
To do this, open File Explorer, right-click "This PC," and select "Map network drive." Select any available drive letter (e.g., Z:) and enter the path to the folder in the following format: \\ComputerName\Folder or \\192.168.1.5\ShareIf you check the "Restore at logon" box, the disk will be available immediately after Windows boots.
This technology is based on the protocol SMB (Server Message Block), which is the de facto standard for Windows local area networks. It provides reliable data transfer and file locking support, preventing conflicts during simultaneous operation.
Comparison of connection methods
There are several ways to set up communication between PCs, and the choice depends on your goals. You can use built-in Windows tools, third-party software like Hamachi (for LAN emulation over the internet), or cloud-based synchronization services. Below is a table to help you choose the best option.
| Method | Speed | Difficulty of setup | Security |
|---|---|---|---|
| Local folder (SMB) | High (depending on Wi-Fi) | Average | High (with password) |
| Exchange with the environment | Average | Low | Average |
| FTP server | Very high | High | Depends on the settings |
| Cloud (OneDrive) | Low (channel limit) | Low | Very high |
For most home tasks, such as watching movies from a media server or transferring documents, a standard SMB is sufficient. However, if you need to connect your local network over the internet to play with a friend, you'll need to use VPN tunnels or specialized software that creates a virtual network adapter.
Frequently Asked Questions (FAQ)
Why does my computer require a password to access a shared folder?
This is the default behavior of the Windows 10 security system when "Password-protected sharing" is enabled. The system requires the credentials of the user who owns the files on the remote computer. You can disable this requirement in the sharing settings if you're on a trusted network, or create identical usernames and passwords on both computers.
Is it possible to link computers if one is on Windows 10 and the other is on Windows 7?
Yes, this is possible, but it may cause issues with the SMBv1 protocol. In Windows 10, it's disabled by default for security reasons, while Windows 7 actively uses it. To resolve this, we recommend updating the SMB client on Windows 7 or (less securely) enabling SMBv1 support in Windows 10 features via "Turn Windows features on or off."
How to find out the IP address of a second computer?
On the second computer, click Win + R, enter cmd and in the black command line window write ipconfigThe required line is called "IPv4 address." You can also see the IP address in the network settings by clicking on the Wi-Fi connection properties.
Does Wi-Fi speed affect file transfer speed?
Absolutely. File copy speed on a local network is limited by the wireless channel's bandwidth. If your router operates at 2.4 GHz, the actual speed is unlikely to exceed 3-4 MB/s. For fast transfers of large amounts of data (4K movies, disk images), it's recommended to use the 5 GHz band or a Gigabit Ethernet cable.
