Wireless local area networks are becoming the standard for modern apartments and small offices. The lack of unnecessary wires and the ability to instantly connect new devices make this method preferable. However, users often encounter difficulties when initially setting up file or printer sharing.
To successfully implement the project, you will need a working one router, supporting Wi-Fi standards, and devices with working network adapters. It's important to understand that connection quality directly depends on the distance to the router and the number of obstacles. Properly configured Windows or macOS software settings will ensure stable data transfer at high speeds.
In this article, we'll cover the process of creating a home network, setting up access rights, and diagnosing common issues. You'll learn how to hide or share network folders from other users and optimize wireless performance. Following these instructions will help you avoid security vulnerabilities in your system.
Necessary equipment and network requirements
The foundation of any wireless local area network is a high-quality router. Modern standard models Wi-Fi 5 And Wi-Fi 6 Provide sufficient bandwidth for transferring large amounts of data and streaming video. Older devices can create a bottleneck, limiting the speed of file transfer between computers.
Each connected device must have a working Wi-Fi module. For desktop PCs without a built-in adapter, an external USB receiver or PCI card will be required. Drivers must be installed and working correctly, as indicated by the absence of yellow icons in the Device Manager.
Particular attention should be paid to security. Use of an encryption protocol WPA3 or at least WPA2 is critical to prevent data interception by attackers. Open networks or the use of outdated WEP make your local network vulnerable to external attacks.

- 📶 No strong interference from microwaves or Bluetooth devices
Basic router setup for local sharing
Before setting up computers, you need to make sure the router is working properly. Log in to the web admin interface, usually accessible at 192.168.0.1 or 192.168.1.1. In the wireless network section, make sure the client isolation feature (AP Isolation) is disabled.
⚠️ Important: Enabling Client Isolation or Guest Network without configuring access rules will prevent devices from seeing each other, even if they are connected to the same router.
To ensure stable operation of local services, it is recommended to reserve IP addresses for key devices. This can be done by binding the MAC address to a static IP in the router's DHCP server settings. This way, the address of the network storage or printer will not change after a reboot.
Check the firewall settings on your router itself. Sometimes built-in filters can block local traffic between LAN ports. Make sure the firewall rules allow communication between devices connected to the internal network.
Configuring network settings in Windows
By default, the Windows operating system can block discovery of other computers for security reasons. To allow data exchange, you need to change the network profile from "Public" to "Private." This can be done through the Network & Internet settings menu.
Open the Control Panel and go to "Network and Sharing Center." Click "Change advanced sharing settings." Here, you need to enable network discovery and file and printer sharing for the current profile.
Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settingsIt's also worth disabling password protection if you trust all devices in your home, or setting up accounts with the same password on all PCs for easy login. This will eliminate constant authorization prompts when trying to open a shared folder.
☑️ Check Windows settings
Make sure all computers are in the same workgroup. By default, Windows uses the name WORKGROUPChanging this setting on different machines may result in them no longer seeing each other in the network environment.
macOS Configuration and Cross-Platform Access
Apple computer users can also easily integrate into a local network. In macOS, open System Preferences and select Sharing. This enables the File Sharing feature, allowing you to add folders for other users.
To connect to a Windows computer from a Mac, use Finder and the Network section. If automatic detection doesn't work, press the key combination Command + K and enter the address in the format smb://computer-IP-addressThe system will ask for your Windows account login and password.
Reverse communication is also possible: Windows 10 and 11 support the SMB protocol used by Apple. However, newer versions of Windows may disable older versions of SMB (v1), which sometimes causes problems connecting to very old network storage devices or printers.
| Parameter | Windows | macOS | Linux (Ubuntu) |
|---|---|---|---|
| Protocol | SMB/CIFS | SMB/AFP | Samba |
| Path to the network | Network environment | Finder -> Network | Nautilus -> Network |
| Connection command | IP address | smb://IP address | smb://IP address |
| Firewall | Windows Defender | Firewall | UFW / iptables |
Organizing shared access to resources
After setting up network discovery, the next step is sharing specific resources. You can share an entire drive, a specific folder, or a connected printer. To do this, right-click the object, select "Properties," and then the "Sharing" tab.
Click the "Advanced Settings" button and check the "Share" box. In the "Permissions" section, you can fine-tune permissions: full access, modify, or read-only. For a home network, read permissions for all users are usually sufficient.
How to hide a folder from prying eyes?
To make a folder hidden on the network, add a dollar sign ($) to the end of the folder name when setting up sharing. For example, the "Secret" folder would become "Secret$." It won't appear in the shared list, but will be accessible via the direct URL.
Don't forget about disk space. If you're sharing a folder with movies or games, make sure you have enough disk space. A local network allows you to stream content directly without taking up space on the receiving device.
The procedure is similar for printers: in the printer properties, on the "Access" tab, enable the corresponding checkbox. Computers on the network will be able to print documents using the drivers installed on the host machine.
Diagnostics and troubleshooting
Even with proper configuration, errors can occur. Computers may not be able to see each other, or access may be blocked by antivirus software. The first step is always to test the connection with the command ping in the command line.
Enter ping 192.168.x.x (where xx is the address of the target computer). If packets are lost, the problem is at the physical level or in the Wi-Fi drivers. If there is a response but the folders are not visible, look for the cause in the firewall settings or Windows services.
⚠️ Note: Third-party antivirus programs (Kaspersky, ESET, Avast) often have their own built-in firewalls that can block local network access even if the standard Windows firewall is configured correctly. Check the "Home Network" settings in the antivirus interface.
It's also worth checking the "WS-Discovery Resource Publishing" service. In some Windows builds, it's disabled, preventing computers from appearing in the list of network devices. You can start it via services.msc.
If the problem persists, try temporarily disabling IPv6 in the adapter properties. Protocol prioritization can sometimes cause conflicts on local networks, especially when using older equipment.
Frequently Asked Questions (FAQ)
Why can't my computer see other devices on the network?
Most likely, your network profile is set to "Public." Switch it to "Private" in the Wi-Fi settings. Also, check if network discovery is enabled in the Network and Sharing Center.
Is it possible to play local games over Wi-Fi?
Yes, many games support LAN mode. However, for a comfortable, lag-free gaming experience, it's recommended to use the 5 GHz band or connect computers via cable, as Wi-Fi is susceptible to interference.
How to transfer a file larger than 4GB over the network?
File size isn't limited by the network, only by the file system. Make sure the drive you're copying data to is formatted as NTFS, as FAT32 doesn't support files larger than 4 GB.
Is it safe to share folders?
If you're on a trusted home network with a strong Wi-Fi password, yes. Enabling public access in public places (cafes, airports) is strongly discouraged.
