Modern online shooters and strategy games often require a stable connection to the developers' servers, which is not always possible if the internet is unstable or you want to play with friends in the same apartment. local area network (LAN) Using a wireless Wi-Fi router allows you to connect multiple computers without the need for extra wires and cables. This is ideal for home tournaments, co-op campaigns, or simply saving bandwidth, as all data exchange occurs within your home network.
Unlike a direct cable-to-cable connection, creating a network through a router requires properly configured network adapters and Windows security settings. Router It acts as a dispatcher, assigning unique IP addresses to each device and ensuring their communication. Despite its apparent complexity, the entire process takes no more than 10-15 minutes if you follow the steps below.
The main advantage of this method is mobility. You can place your laptop anywhere in the room where there's a signal and continue playing without losing connection with the host. However, it's important to keep in mind that for a comfortable, lag-free gaming experience, a strong wireless signal and the absence of interference from nearby networks are critical. Below, we'll cover all the technical details that will help you launch your game without any issues.
Necessary equipment and network requirements
Before you begin software configuration, you need to make sure your hardware meets the basic requirements. To set up a stable local network, you'll need a Wi-Fi router that supports the following standards: 802.11n, 802.11ac or newer. Older devices that only operate at 2.4 GHz in noisy environments can create noticeable lag in fast-paced games, so using a dual-band router (5 GHz) is preferable.
All computers participating in the game must be connected to the same wireless network. This means they must enter the same Wi-Fi password and be within range of a strong signal. If one PC is connected via cable and the other via wireless, the network will still work, but firewall settings may require additional attention.
It's important to check the network cards on all devices. They should be working correctly in Device Manager, without yellow exclamation marks. Drivers should be up-to-date, as older adapter software may incorrectly handle broadcast packets used to find servers.
Configuring network settings in Windows
The first step is to make your network profile discoverable by other devices. By default, Windows installs the "Public Network" profile, which blocks incoming connections for security reasons. You need to switch it to "Private Network."
To do this, open your network settings, go to your Wi-Fi connection properties, and select the "Private" network type. This will allow your computer to be visible to other devices on the local network. Without this step, the computers simply won't be able to see each other, even if the IP addresses are configured correctly.
Next, you need to enable network discovery and file sharing. Go to "Control Panel" → "Network and Sharing Center" → "Change sharing settings." In the "Private" profile, enable the following:
- 📡 Turn on network discovery.
- 💾 Enable file and printer sharing.
- 🔐 Let Windows manage HomeGroup connections.
After making changes, be sure to click "Save Changes." Restarting your computer is not required, but may be necessary for some security policies to apply, especially if you were previously using public networks.
Setting up static IP addresses
Although the router automatically distributes addresses via DHCP, for stable gaming on a local network it is better to register static IP addresses Manually. This ensures that the host address (the game creator) doesn't change during the game, and that other players don't lose their connection due to the address lease expiring.
To configure, click Win + R, enter ncpa.cpl and press Enter. Find your wireless connection, right-click it, and select "Properties." Find "Internet Protocol Version 4 (TCP/IPv4)" in the list, select it, and click "Properties" again.
Select the "Use the following IP address" option and enter the information. If your router's address is, for example, 192.168.0.1, then the settings for the first PC will be:
- 🌐 IP address: 192.168.0.10 (the last digit can be from 2 to 254).
- 🚪 Subnet mask: 255.255.255.0 (will be filled in automatically).
- 🏠 Default gateway: 192.168.0.1 (your router's address).
On the second computer, enter the IP address 192.168.0.11, on the third, 192.168.0.12, and so on. You can specify DNS servers manually (for example, Google's: 8.8.8.8) or leave them retrieved automatically if the internet connection through the router is stable.
Windows Firewall Configuration
A firewall is your system's first line of defense, but it's also the one that most often blocks connections in local games. If you've configured your network and IP address, but games still can't see the servers, this is the problem in 90% of cases.
You need to add an exception for a specific game or allow the app through your firewall. Open Control Panel → Windows Defender Firewall → Allow an app... Click "Change settings" and find your game in the list (e.g., Minecraft, CS 1.6, Terraria).
| Rule type | Action | Profile | Note |
|---|---|---|---|
| For the program | Allow connection | Private | Basic rule for LAN |
| For the port | Allow connection | All | If the game is not on the list |
| ICMP rule | Allow echo request | Private | To check the connection (Ping) |
If the game you want is not listed, click Allow another app, select Browse and locate the game's executable file (.exe). Be sure to check the boxes next to "Private" and, if desired, "Public" (although this is less secure for public networks).
⚠️ Note: If you can't find the game in the list or it's using non-standard ports, it's easier to temporarily disable your firewall completely to test. If the network works after disabling it, then the problem is with the blocked ports. Don't forget to re-enable the firewall and configure the targeted rule!
Creating and connecting to the game
Once the network is successfully configured, one computer should act as the host (server). Launch the game and select "Create Game" or "Local Area Network" (LAN) mode. Server settings often allow you to set a name that will be visible to other players and select a map.
The remaining players open the game and select "Multiplayer" → "Local Area Network" (LAN). The host computer should appear in the list of available servers. If it doesn't, use the "Direct Connect" function and enter the host IP address you specified earlier (e.g., 192.168.0.10).
☑️ Checklist before launching the game
Some older games may require you to add a server by IP. Enter the address in the appropriate field and click "Connect." If all computers are running the same game version (same patch), the connection should be established instantly.
What if the game requires the same versions?
Make sure all PCs have the same mods, maps, and patches installed. Even a single version difference can prevent connection. Check the game shortcut properties or the "About" menu.
Diagnostics and troubleshooting
Even with proper configuration, errors may still occur. The easiest way to diagnose this is by using a utility. pingOpen a command prompt (cmd) on the client computer and enter the command:
ping 192.168.0.10 -tIf you see a "Request timed out" response, it means the computers aren't communicating with each other at the ICMP protocol level. Check if network discovery is enabled and if your antivirus isn't blocking connections. If responses arrive in less than 10-20 ms, the network is working fine, and the problem should be looked for in the game's settings or its firewall.
A common issue is time synchronization issues or differences in Windows user accounts. Ensure that the same date and time are set on all PCs. Also, try creating a local user with the same name and password on all computers, although this is rarely necessary for modern games.
⚠️ Note: Game and operating system interfaces are subject to update. If you can't find the menu item, search for it in Windows settings or refer to the official documentation for the specific game, as the paths to the settings may change.
Optimizing Wi-Fi for Gaming
A wireless connection is always less stable than a wired one. To minimize lag and packet loss, try placing the router centrally. Avoid placing the router near microwave ovens, baby monitors, and Bluetooth devices, which interfere with the 2.4 GHz band.
If your router is dual-band, be sure to connect your gaming PCs to the network. 5 GHzThis range provides higher speeds and is less susceptible to interference from neighboring networks. However, keep in mind that the 5 GHz signal has poorer penetration through walls, so keep the distance from the router as short as possible.
You can also try changing the Wi-Fi channel to a less congested one in your router settings. To do this, use special apps on your smartphone (such as Wi-Fi Analyzer) to see which channels are free and switch the router to them through the web interface (usually 192.168.0.1 or 192.168.1.1).
Why doesn't the game see other computers even though there is internet?
The problem is most likely with your network profile. If Windows considers your network "Public," it's hiding your computer from others. Check if the network type is set to "Private" and ensure network discovery is enabled.
Is it possible to play via Wi-Fi if one PC is connected via cable?
Yes, you can. A router connects wired and wireless devices into a single local network. The key is that they all receive IP addresses from the same subnet (e.g., 192.168.0.x).
Do you need internet to play on a local network?
No, an internet connection is not required. A local network works offline. However, you may need one to check for game updates or activate license keys before launching.
How to find out your IP address on a local network?
Open command prompt (cmd) and enter the command ipconfigFind the "IPv4 Address" line in the section for your wireless adapter. This is your connection address.
