Establishing a local connection between laptops is a basic task for transferring large amounts of data or collaborating on projects without the use of external storage. In the operating system Windows 10 This process is automated, but requires proper configuration of security profiles and detection parameters. If you're connected to the same router, creating a bridge between your devices will only take a few minutes.
Modern file transfer methods, such as cloud storage, are often limited by internet speeds or provider plans. LAN allows you to use the full bandwidth of your Wi-Fi router, ensuring stable transfer speeds for gigabytes of information. This is especially relevant for video editors, designers, and system administrators.
In this guide, we'll cover all the configuration details, from changing the network type to port forwarding and shared folders. You'll learn how to avoid common mistakes when computers are physically connected but don't "see" each other in the network environment. Having a system ready for local operation is a key factor for success.
Checking requirements and preparing equipment
Before you begin any deep setup, you need to make sure your infrastructure is ready for use. The basic requirement is that all laptops must be connected to same Wi-Fi routerUsing guest networks or isolated VLANs can block device discovery even if the IP addresses are on the same subnet.
Make sure all devices have the latest drivers for their wireless adapter. Outdated software may not correctly handle multicast packets required for the discovery protocol. LLMNR And NetBIOSAlso check that your antivirus software is not blocking local connections in the private profile.
It's important to consider the physical limitations of a wireless connection. If laptops are in different rooms with two solid walls, the transfer speed may be unstable. Ideally, all devices should be within range of a strong signal to ensure maximum performance. throughput channel.
Setting up the network type and discovery profile
The first critical step is to change your network profile from "Public" to "Private." Windows 10 assigns new connections to the "Public" profile by default, which hides your computer from other devices for privacy purposes. securityTo work in a local environment, this mode must be switched.
Open the Start menu and go to Settings → Network & Internet → StatusClick on your Wi-Fi connection properties. In the window that opens, select the "Private" network type. This will allow the system to respond to discovery requests and open ports for local traffic.
⚠️ Caution: Switching to "Private Network" mode makes your laptop visible to other devices on this Wi-Fi network. Avoid using this profile in public hotspots, such as cafes or airports, to avoid potential attacks.
After changing your profile, check your sharing settings. Go to Control Panel → Network and Sharing Center → Change advanced sharing settingsIn the Private section, make sure the "Turn on network discovery" and "Turn on file and printer sharing" options are enabled.
Unification of workgroup and computer names
For devices to display correctly in the network environment, they must be in the same workgroup. By default, Windows uses the name WORKGROUP, but in corporate environments it may differ. Mismatched workgroup names are a common reason why computers don't see each other.
You can check and change the workgroup name using the "System" menu. Right-click "This PC," select "Properties," and then click "Advanced system settings." Under the "Computer Name" tab, ensure that the same workgroup name is specified on all laptops.
☑️ Check names and groups
It's also critical that the computer names themselves be unique. If two laptops on the network are named, for example, "Laptop," an addressing conflict will occur, and one of the devices will become unavailable. Rename the devices by adding numbers or usernames, for example, Home-PC-01 And Home-PC-02.
How to rename a computer using the registry
If the interface is not available, open regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName and change the ComputerName parameter, which will require a reboot.
After making changes, the system will require a reboot. This is a mandatory procedure, as the services NetBIOS and the network browser are initialized only at system startup. Without a reboot, new names may not register in the router's routing table.
Setting up shared access to folders and files
After configuring your network settings, you need to define the resources that will be available to other users. You can share any folder on your drive, making it visible on your local network. To do this, right-click the folder, select "Properties," and go to the "Sharing" tab.
Click the "Advanced" button and check the "Share this folder" box. In the "Permissions" menu, you can fine-tune permissions: Full Control allows you to modify and delete files, while Read Control only allows you to view them. For secure sharing, it's best to use the "Share this folder" mode. "Reading".
| Permission type | User actions | Recommended use |
|---|---|---|
| Full access | Read, write, delete, change permissions | Working folders for joint projects |
| Change | Reading, writing, deleting files | Temporary file sharing folders |
| Reading | View and copy only | Media libraries and archives |
An alternative and more modern method is to use the Sharing feature. In the folder properties, on the Sharing tab, click the Share button and select a user. Everyone or a specific system user. This method is easier for beginners and automatically configures the necessary file system permissions. NTFS.
Mapping a network drive and troubleshooting errors
To avoid searching for shared folders each time through Network Places, it's easier to map them as a network drive. Open "This PC" and click "Map network drive" in the top menu. In the "Folder" field, enter the path to the resource in the following format: \\ComputerName\Folder or \\IP address\Folder.
⚠️ Note: If you receive the "Windows cannot access" error when connecting, try using the IP address instead of the computer name. DNS name resolution issues are common on home networks without a dedicated server.
A common problem is the password requirement. Even if you have a passwordless login, Windows may prompt you for credentials. Enter the login and password for the user account on the remote computer. To simplify matters, you can create identical accounts with the same passwords on all laptops on the network.
If the computers are still not visible, check Windows services. Click Win + R, enter services.msc and find the "Discovery Resource Publishing" and "Discovery Device Host" services. They should be started and running in automatic mode.
Security and access rights management
An open local network is potentially vulnerable if an intruder gains access. It is recommended to disable password-protected sharing only in a fully trusted home environment. In the office or when you have guests, it's best to leave it enabled to control who exactly has access to your data. files.
Regularly check the list of connected devices on your router. Unknown MAC addresses may indicate unauthorized access to your Wi-Fi network. Use encryption. WPA3 or WPA2-AES to protect the wireless data transmission channel.
⚠️ Note: Windows settings interfaces and menu item names may vary slightly depending on the update version (21H2, 22H2, etc.). If you can't find a specific item, use the system settings search.
For maximum security, create a separate user with limited privileges specifically for network access. Avoid using the administrator account to share folders unless absolutely necessary. This minimizes the risk in the event of a network compromise.
Frequently Asked Questions (FAQ)
Why can't my laptop see another computer on the network?
Most often, the problem lies with the network profile. Make sure the network type is set to "Private" on both devices. Also, check that the "Discovery Resource Publishing" service is enabled and that a firewall or antivirus isn't blocking the connection.
Is it possible to set up a network if the routers are different?
Yes, if both routers are on the same subnet (e.g., 192.168.1.x) and connected by cable, or if one of them is operating in access point mode. However, for ease of setup, it's best to use a single primary router.
How to transfer a file without setting up shared folders?
Windows 10 features Nearby Sharing. It uses Bluetooth and Wi-Fi to quickly transfer files between devices signed in to a Microsoft account, similar to Apple's AirDrop.
Do you need a static IP for your network to work?
For basic file sharing, a dynamic IP (DHCP) is perfectly adequate. A static address is only necessary if you're setting up a server, printer, or specific applications that require a permanent address.
