Organizing a local network between two computers running an operating system Windows 7 — a task often faced by users who want to share files or play wirelessly over a local network. Although this OS no longer receives security updates, it remains popular on older machines, where establishing a local connection requires a special approach to configuring protocols and services.
The setup process assumes both devices are already connected to the same wireless router. You won't need to run an Ethernet cable between the system units, as all data will be transmitted wirelessly. However, keep in mind that file transfer speed will directly depend on the signal quality and the Wi-Fi standard supported by your adapters.
Before changing system settings, make sure the network adapter is enabled on both computers and the drivers are working correctly. Incorrect firewall or antivirus settings can block detection of the second computer, even if a physical connection to the router is established successfully. Carefully following the instructions will help avoid common errors and quickly establish data exchange.
Checking hardware and drivers
The first step to a successful connection is to diagnose the physical hardware. You need to ensure that the Wi-Fi adapters on both computers are functioning properly and can see the wireless network. If one of the devices displays "No connection," further configuration of local file sharing is pointless.
Open Device Manager and check for yellow exclamation marks next to your network adapters. If you don't see any, it means drivers The hardware is installed correctly and ready for use. If errors persist, you will need to reinstall the software for your network controller.
How to quickly check the adapter status?
Press Win+R, type ncpa.cpl, and press Enter. In the window that opens, you'll see all your network connections. If the wireless network icon is gray, the adapter is disabled either by software or by physical means.
It's also important to check whether the wireless module itself is enabled. Laptops often have a physical switch or function key (e.g., Fn+F2) that can block the radio module. Make sure the Wi-Fi indicators are lit and the system doesn't report a hardware disconnect.
Setting up names and workgroups
In order for computers to be able to “see” each other in a network environment, they must be in the same working group and have unique names. By default, Windows 7 uses the group name WORKGROUP, and changing it to something exotic is not recommended due to compatibility issues.
To change your computer's name, go to the Control Panel and select the "System" section. Here you'll see the current device name and the option to change the settings. Each PC on your network should be assigned a unique name, such as PC-HOME And PC-OFFICEto avoid addressing conflicts.
- 🖥️ Right-click on “Computer” and select “Properties.”
- 🔧 Click the "Change settings" link to the right of the device name.
- ✏️ In the "Computer name" field, enter a unique name in Latin characters without spaces.
- ✅ Make sure that the "Workgroup" field on both PCs is set to the same word, for example, WORKGROUP.
After making changes, the system will require a reboot. This is a mandatory step, as the new network IDs only take effect after the services are restarted. Don't ignore the reboot request, otherwise the second computer may not appear in the list of available devices.
Selecting a network type and access profile
A critical step in Windows 7 is choosing a network type when you first connect. The system will prompt you to select a location: "Home," "Work," or "Public." To create a local network between two PCs, select the "Home Network" or "Work Network" profile.
If you select "Public Network," the operating system will automatically enable enhanced security mode, hiding your computer from detection by other devices. In this mode, file and printer sharing will be blocked by default, making connection impossible.
⚠️ Note: If you've already selected "Public Network," you don't need to reconnect. You can change the profile manually through the Network and Sharing Center, but it's easier to delete the network (forget the network) and reconnect, selecting the correct type.
After selecting the "Home Network" profile, the system will prompt you to create a HomeGroup. This is a convenient tool for quickly sharing libraries, but for a simple connection between two PCs, you can do without it by setting up access manually. The main thing is to ensure that network discovery is enabled in the Network and Sharing Center.
Enable network discovery and sharing
The basic mechanism that allows computers to find each other is called network discoveryWithout this feature enabled, your PC will be "invisible" to your neighbors via Wi-Fi, even if all other settings are correct. This setting is located in the advanced sharing settings.
To activate, go to "Network and Sharing Center," then select "Change advanced sharing settings." Here, you need to expand the profile for your current network (Home or Work) and toggle the switches to "On."
Path to settings: Control Panel → Network and Internet → Network and Sharing Center → Change advanced sharing settingsPay special attention to the "Password-protected sharing" option. If you enable this option, the system will prompt you for the remote PC's username and password when attempting to access files from another computer. For a home network, it's more convenient to select "Disable password-protected sharing" to ensure immediate access.
☑️ Sharing settings
Expanding access to specific folders
After configuring network settings, you need to explicitly tell the system which resources you're willing to share. Simply enabling sharing isn't enough—you need to share specific directories. This can be done through folder properties or the "Sharing" menu.
Select the folder you want to make visible to the second computer, right-click it, and go to Properties. On the "Sharing" tab, click "Advanced" and check "Share this folder." Then click "Permissions" to configure user permissions.
| Permission type | Full access | Change | Reading |
|---|---|---|---|
| Full access | Allow | Allow | Allow |
| Change | Ban | Allow | Allow |
| Reading | Ban | Ban | Allow |
| Ban everything | Ban | Ban | Ban |
In the permissions window, you can add the "Everyone" group if you want anyone connected to Wi-Fi to see the files. If security is a concern, add a specific user. Once the settings are applied, the folder will be accessible via a network path, for example, \\COMPUTER_NAME\Folder.
Firewall Configuration and Troubleshooting
It often happens that all the settings are correct, but the connection fails due to ports being blocked by the built-in Windows firewall or a third-party antivirus. You need to ensure that the local network rules allow incoming connections.
Go to the Firewall control panel and select "Allow a program or feature through Windows Firewall." Find "File and Printer Sharing" in the list and make sure the box next to your network type (Home/Work) is checked.
⚠️ Note: If you're using a third-party antivirus (Kaspersky, ESET, Avast), it may have its own firewall that ignores Windows settings. In this case, you'll need to find the network settings in the antivirus interface and change the profile to "Trusted Network."
If the computers still can't see each other, try resetting the network settings. Open a command prompt as administrator and enter the reset protocols command. This will help resolve cached DNS and NetBIOS errors, which often prevent device discovery in older operating systems.
netsh winsock resetnetsh int ip reset
ipconfig /flushdns
After running the commands, be sure to restart your computer. In most cases, this resolves network visibility issues when software glitches prevent the TCP/IP stack from functioning properly.
Why isn't public access working?
A common cause is a disabled service, either the "Discovery Resource Publishing" or "Browser Computer." Check their status in services.msc and set the startup type to "Automatic."
Frequently Asked Questions (FAQ)
Is it possible to connect computers if one is on Windows 7 and the other is on Windows 10?
Yes, this is possible. However, on Windows 10, you may need to enable SMB 1.0 support, as Windows 7 uses this protocol by default for network discovery. Also, make sure both PCs are in the same workgroup.
Why does it ask for a password when I access a folder, even though I disabled it?
This can happen if the target computer has an account with a blank password, but the security policy prohibits network logins with blank passwords. Alternatively, try creating identical accounts (login and password) on both computers.
What is the maximum speed when transferring via Wi-Fi?
Speed depends on the Wi-Fi router standard and adapters. For 802.11g, the actual speed will be around 2-3 Mbps, while for 802.11n, it will be up to 10-15 Mbps. A wired connection will always be faster and more stable.
How to find out the IP address of the second computer for direct connection?
On the second computer, press Win+R, enter cmd, then in the black window enter ipconfigYou're looking for the "IPv4 address" line. You can connect by entering it in the address bar of Explorer. \\192.168.1.XX.
