Organizing wireless data exchange between devices is not just a convenience, but often a necessity for quickly transferring large files or collaborating. In the operating system Windows 10 The process of creating a wireless connection has been significantly simplified compared to previous versions, but it still requires careful attention to security settings and network profiles. Many users still believe that creating a wireless connection requires local network A physical router is required, but this is not the case.
Modern technologies allow you to combine PCs, laptops and tablets into a single infrastructure using built-in adapters Wi-FiThis solution is ideal for temporary offices, gaming parties, or situations where a wired connection is not possible. It's important to understand that properly configuring access profiles and network protocols is the foundation for the stable operation of the entire system.
In this guide, we'll walk you through every setup step, from checking drivers to setting folder permissions. You'll learn how to avoid common connection errors and ensure secure data exchange. The fastest way to connect in Windows 10 is to use the Mobile Hotspot feature or set up a Computer-to-Computer (Ad-Hoc) network via the command line.
Checking hardware and drivers before setup
Before attempting complex network settings, ensure the hardware is working properly. The wireless adapter must be enabled and its software must be functioning correctly. Device visibility issues are often caused by outdated drivers or a disabled service.
Open Device Manager and find the "Network Adapters" section. If a yellow triangle appears next to your Wi-Fi module's name, the driver is not working properly. In this case, you need to download the latest software from the laptop or motherboard manufacturer's website. If the Wi-Fi module is not working properly, you should: adapter network creation is impossible.
It's also worth checking whether the wireless function is physically enabled. Many laptops have a key combination (usually Fn + F2 (or the button with the antenna icon), which completely disables the module. Make sure the Wi-Fi indicator is on and the system can see available wireless networks.
⚠️ Note: If you're using an external USB Wi-Fi adapter, try switching it to a different port. USB 3.0 ports (blue) can interfere with the 2.4 GHz signal, reducing connection stability.
After checking the hardware, restart the computer. This will reset temporary network configurations and restart all necessary services. Only after ensuring the hardware is working properly can you proceed to software configuration.
Make sure that all computers you plan to integrate have the same versions of security protocols installed, such as WPA2-PersonalIncompatibility of encryption standards is a common reason why devices don't see each other in the list of available connections.
Setting up the network type and access profile
The key point in organizing data exchange is the correct choice of network profile. Windows 10 By default, it assigns new connections to the "Public Network" profile, which hides your computer from other devices for security purposes. For a local network, you need to change this setting.
Go to the Start menu and select Settings (the gear icon). Then, follow the path: Network & Internet → Status. Under Properties, you'll see your current connection profile. Click it and select the "Private" option. This will open ports so that other users can discover your device.
After changing your profile, the system will automatically enable network discovery. However, manual activation is sometimes required. Go to "Control Panel" → "Network and Sharing Center" → "Change advanced sharing settings." Here, you need to enable the following options:
- 📡 Turn on network discovery.
- 📂 Enable file and printer sharing.
- 🔐 Allow management of HomeGroup connections.
Don't forget to save your changes by clicking the "Save Changes" button at the bottom of the page. Without this step, all further settings will be useless, as the operating system will block incoming connection requests.
If you're setting up a network in a public place (cafe, coworking space), using the "Private" profile carries risks. In this case, it's better to create a separate guest network on the router or use a VPN. However, for home use, this profile is mandatory.
Creating a wireless network using the command line
The built-in utility is ideal for creating an access point without using third-party software. netshThis method allows you to turn your computer with a Wi-Fi adapter into a fully-fledged router that other devices can connect to.
Launch the Command Prompt as administrator. To do this, right-click the Start menu and select Windows PowerShell (Admin) or Command Prompt (Admin). Enter the following command to create the virtual adapter:
netsh wlan set hostednetwork mode=allow ssid=MyLocalNetwork key=MyPassword123In this team ssid - This is the name of your network that other devices will see, and key — connection password (minimum 8 characters). After entering the command, press Enter. If successful, you will see a message stating that the hosted network has been created.
Next, you need to start the network with the command:
netsh wlan start hostednetworkNow on other devices in the list of available Wi-Fi networks will appear MyLocalNetworkHowever, in order for devices to exchange data and access the Internet (if required), sharing must be set up.
☑️ Checking network settings
Return to "Network and Sharing Center" → "Change adapter settings." Find the connection through which your PC receives internet (e.g., Ethernet), right-click it → "Properties" → "Sharing" tab. Check "Allow other network users to connect through your internet connection" and select the virtual network you created from the list.
⚠️ Attention: Teams
netshThese commands are case-sensitive and space-sensitive. If the command fails, check for extra characters or typos in the network name and password.
Setting up shared access to folders and printers
After successfully connecting computers into a single network, the question of file exchange arises. Windows 10 Allows you to share any folder, making it visible to other network members. This eliminates the need to use flash drives or cloud storage for transferring large amounts of data.
Select the folder you want to share. Right-click it, select "Properties," and go to the "Sharing" tab. Click "Advanced" and check "Share this folder."
Setting access rights is important. Click the "Permissions" button. Here you can specify what other users can do: only read files or also modify and delete them. For a home network, the "Everyone" group with "Read" and "Modify" permissions is usually sufficient.
The procedure for accessing shared printers is similar. Go to "Settings" → "Devices" → "Printers & Scanners." Select the desired printer, click "Manage" → "Printer Properties" → the "Sharing" tab, and check the "Share this printer" box.
| Access type | Description | Recommended use |
|---|---|---|
| Reading | The user can only open and copy files. | Exchange documents, photos, and music |
| Change | The user can edit and delete files | Collaborating on projects |
| Full access | Full control over the folder and rights | For trusted administrators only |
Remember that granting full access to the "Everyone" group on an office computer can lead to the leak of confidential information. Always adhere to the principle of least privilege.
Connecting to the network and troubleshooting
If all settings are correct, the host computer's name should appear in the "Network" section of the client computer's File Explorer. When you attempt to log in, the system may prompt you for a username and password. Enter the host computer's username and password (Windows login).
A common issue is the error "Windows cannot access...". In this case, check whether the "SSDP Discovery Service" and "Discovery Provider Host Service" services are enabled. They should be running in automatic mode.
Also, make sure your antivirus or firewall isn't blocking the connection. Try temporarily disabling your third-party antivirus and testing access. If the issue resolves, add an exception rule for the local network in your firewall settings.
- 🔍 Check if the computers are in the same workgroup (usually
WORKGROUP). - 🔌 Make sure both devices are connected to the same subnet (the first three digits of the IP address must match).
- 🔄 Restart the Print Spooler service if the printer is not visible.
What to do if computers can't see each other?
Ensure that the "Connect Now Discovery Resource Publishing" service is enabled on both PCs. Also, try manually entering static IP addresses in the IPv4 protocol properties to avoid DHCP addressing conflicts.
Sometimes resetting your network settings helps. In the network settings, there's a "Network Reset" button that will reinstall the drivers and restore the settings to factory defaults. This is a last resort, but it often resolves mysterious compatibility issues.
Wireless LAN Security
When setting up a wireless network, keep security in mind. Openly accessible files can become a backdoor for attackers if they gain access to your Wi-Fi. Use strong passwords for your Windows accounts.
Encryption Traffic on the local network is also important. Make sure your Wi-Fi network is protected by a protocol WPA2 or WPA3Older WEP protocols are easily cracked and do not provide adequate data protection during transmission.
If you use the network only to transfer files between your devices, consider disabling internet access for that specific network. This will create an isolated segment (Air Gap) that prevents viruses from penetrating from the global network.
⚠️ Note: Settings interfaces and menu item locations may vary depending on your Windows 10 build version and security updates. If you can't find the item, use the settings search or refer to the official Microsoft documentation.
Regularly update the firmware of your router and network adapters. Manufacturers frequently release patches to address vulnerabilities in wireless protocols.
FAQ: Frequently Asked Questions
Is it possible to connect computers to a network without a router?
Yes, this is possible. You can create a computer-to-computer (Ad-Hoc) network or use one of the laptops as an access point using the Mobile Hotspot feature or the command line, as described above.
Why can't computers see each other in a network environment?
Most likely, the network profile is set to "Public." Also, check that network discovery is enabled in the advanced sharing settings and that the necessary Windows services are running.
Do I need the same password to log into Windows on all PCs?
