Modern home networks have long ceased to be limited to simple Internet access. Local area network (LAN) allows devices to exchange data directly, bypassing external servers. This opens up opportunities for quickly transferring large files, streaming content to a TV, or using a network printer without the hassle of wires.
Connection via Wi-Fi This eliminates the need to run cables throughout the apartment, but requires proper software configuration. Without proper operating system and router configuration, devices will see the internet but remain "invisible" to each other. In this article, we'll cover all the steps for creating a stable wireless connection for data exchange.
First, you need to ensure that all devices are on the same wireless network. This is a basic requirement, without which further steps are pointless. The router must be configured to operate in access point (AP) or router mode, not client or extender mode, unless you are using a complex cascaded setup. After checking the physical connection, we move on to the software part.
Checking Windows network profile settings
The Windows operating system treats new connections as public by default. In this mode network discovery Disabled for security purposes, this makes your computer hidden from other devices. The first step is to change the network profile to "Private."
To do this, open the network settings from the taskbar or Start menu. Under "Status," find the properties of your Wi-Fi connection. Here, you'll need to toggle the switch from "Public" to "Private." This will allow the system to open ports for local traffic exchange.
⚠️ Important: By switching your profile to "Private," you make your PC visible on the current network. Only do this on trusted home networks, but avoid doing so in cafes or airports.
After changing your profile, the system may ask for permission to discover other devices. Accept this request to complete the initial security setup. Your computer is now ready to search for network neighbors.
Turn on network discovery and sharing
Changing your network profile is only half the battle. You need to enable specific services responsible for visibility. Go to Control Panel and navigate to Network and Sharing Center. On the left, select Change advanced sharing settings.
In the window that opens, you'll see several profiles: private, guest, and all networks. For the private profile, follow these steps:
- 🔘 Enable network discovery and automatic configuration of connected devices.
- 📁 Enable file and printer sharing.
- 🔐 Allow Windows to manage HomeGroup connections (if used).
Pay special attention to the "All Networks" section. It's important to enable sharing here so that users of other Windows versions can access folders. It's also recommended to disable password-protected access if you're in a fully trusted home environment. This will prevent constant login prompts when connecting from a TV or smartphone.
Don't forget to click the "Save Changes" button at the bottom of the page. Without this step, all settings will remain temporary and will be reset after a reboot.
Setting up shared access to folders and printers
To make your files visible to other devices, you need to share specific directories. Select the folder you plan to use as storage. Right-click it and select "Properties." Go to the "Access" tab and click "Advanced Settings."
Check the "Share this folder" box. Under "Permissions," ensure the "Everyone" group has read permissions (or modify permissions, if you need to write files from other devices). You can do the same in the "Security" tab by adding a user there. Everyone with the necessary rights.
The procedure is similar for printers. Go to "Devices and Printers," select your printer, click "Printer Properties" (not just Properties), and in the "Sharing" tab, check "Share this printer." Give it a descriptive network name without spaces, for example, HP_LaserJet_Office.
☑️ Check resource sharing
Once the resources are configured, they will be accessible via a network path. This can be found by opening the folder or printer properties. Typically, the path looks like this: \\Computer_Name\Folder or \\192.168.1.X\Folder.
Router configuration and IP addressing
The stability of a local network directly depends on the correct distribution of IP addresses. The router must assign addresses from the same subnet to all devices. Log into the router's web interface (usually at 192.168.0.1 or 192.168.1.1) and find the "Address" section. DHCP server.
Make sure the server is running. The address range should be sufficient for all your devices. For example, a pool from 192.168.1.2 to 192.168.1.254. It's important to use the default subnet mask— 255.255.255.0If the mask is different, devices may not "see" each other even on the same Wi-Fi.
| Parameter | Recommended value | Description |
|---|---|---|
| Router IP address | 192.168.1.1 | Default gateway for clients |
| Subnet mask | 255.255.255.0 | Determines the size of the local network |
| DHCP Start | 192.168.1.2 | First distribution address |
| DHCP End | 192.168.1.254 | Last address for distribution |
For stationary devices such as NASFor storage devices or network printers, it's recommended to configure a static IP address or reserve an address in DHCP using the device's MAC address. This ensures that the resource path doesn't change after a router reboot.
⚠️ Note: Router interfaces from different manufacturers (Asus, TP-Link, Keenetic, MikroTik) may vary significantly. The location of DHCP and LAN settings varies, so please consult the official documentation for your model.
What to do if IP addresses conflict?
If two devices receive the same IP address, one of them will lose network connectivity. Solution: Restart the router to reset the address lease, or manually change the IP address on one of the conflicting devices in the TCP/IP settings.
Connecting Android and iOS devices
Mobile devices can also be a fully-fledged part of a local network. To access a computer from a phone or tablet, the standard File Explorer app isn't enough. You'll need a third-party client app that supports the protocol. SMB (Server Message Block).
Popular solutions are VLC Player to watch the video, FE File Explorer or Owlfiles to manage files. In the app, select to add a new connection of the "Local Area Network" or "SMB" type. The app will automatically scan the network and find available computers.
If the automatic search doesn't yield results, try connecting manually using the IP address. Enter the computer's address (e.g., 192.168.1.50). The system may prompt you for a username and password. It's important to enter the credentials for the Windows account you're logged in with, not the computer name.
On devices Android TV or prefixes like Apple TV And Mi Box The situation is similar. Built-in media players often have a "Network" or "LAN" function that displays available resources. If the built-in player doesn't see the folders, install Kodi or Nova Player - they have excellent support for network protocols.
Diagnosing and troubleshooting access issues
Even with proper configuration, errors can still occur. Computers are online, but folders won't open, or the device doesn't appear in the list at all. The first diagnostic tool is the command line.
Launch the command prompt (cmd) as administrator. Enter the command ping 192.168.1.X (where X is the target device's address). If responses are received, there's a physical connection, and the issue lies with the access settings or firewall. If requests time out, check your Wi-Fi connection and router settings.
A common problem is blocked ports by antivirus software or Windows Firewall. Try temporarily disabling these protections to see if that's the issue. If access is restored after disabling them, add an exception rule for "File and Printer Sharing" in your firewall settings.
It's also worth checking Windows services. Click Win + R, enter services.msc and find the following services:
- 🛠 Publishing function discovery resources.
- 🔍 Computer Browser service.
- 📡 Function discovery provider host.
Make sure these services are running and their startup type is set to "Automatic." Failure to run any of them may result in your computer being invisible in the network, although access via a direct IP address will still work.
⚠️ Warning: The SMBv1 protocol is deprecated and disabled by default in modern versions of Windows due to vulnerabilities. If you're connecting a very old device (such as an older Smart TV or set-top box) that only supports SMBv1, you'll need to enable it manually using "Turn Windows features on or off," but this reduces network security.
Local network security
By making files accessible, you potentially expand your attack surface. Even on a home network, it's important to practice basic hygiene. Your Wi-Fi password should be complex and use standard encryption. WPA2/WPA3The old WEP protocol can be cracked in minutes.
If guests occasionally connect to your network, create a separate "Guest Network" for them in your router settings. This feature isolates guest devices from your main LAN, allowing them to only access the internet. Your files and printers will remain inaccessible to guests.
Update your router firmware regularly. Manufacturers patch security holes that can allow attackers to access your local network from outside. Also, change the default router administrator password, which is often set to "admin/admin."
Is it possible to hide a network's SSID for security?
Hiding the network name (SSID) doesn't provide real protection. Specialized software can easily detect hidden networks. It's better to use MAC address filtering for critical devices, although this isn't a panacea.
Why is my computer not visible on the network even though the internet is working?
Most often, the problem lies in the "Public" network profile. Windows blocks discovery on such networks. Check whether the "Private" profile is set and that the network discovery service is enabled.
How to find out the IP address of another device on the network?
Use the command arp -a in the command line. It will display a table of IP addresses and physical MAC addresses of all devices your computer has recently communicated with.
Is it safe to disable password when sharing?
In a purely home network with no outside Wi-Fi connections, this is acceptable for convenience. However, if you have smart devices (cameras, sockets) with weak security, it's better to leave passwords on or use a guest network for IoT devices.
What should I do if my TV can't see my computer via Wi-Fi?
Make sure both devices are connected to the same router (not to different mesh system access points if they are separated by 2.4 and 5 GHz bands without roaming). Try manually entering the computer's IP address in the TV app.
Is it possible to create a local network without a router?
Yes, you can create a computer-to-computer (Ad-Hoc) network or distribute Wi-Fi from a laptop, but this is less stable and functional than using a full-fledged router with a DHCP server.
