Modern online games often require a stable connection to the developers' servers, but nothing can replace the atmosphere of live communication with friends, when you are all in the same room or even in different cities, but united by a common goal. local network (LAN) via a home WiFi router is a great way to play classic shooters, strategy games, or simulations without the lag typical of a global network and without having to run long cables through the entire apartment.
Many users mistakenly believe that wired connections are essential for multiplayer gaming, but modern wireless standards allow for high-speed data transfer, sufficient for most gaming genres. Proper network hardware and operating system configuration are key, as Windows often blocks detection of other computers by default for security reasons. Understanding how it works IP addressing and a firewall will help you launch the game quickly.
In this article, we'll walk you through every step of setting up a gaming space: from checking the physical connection to fine-tuning sharing settings. You'll learn how to avoid common mistakes that cause computers to "not see" each other and how to optimize your router to minimize ping. Even if you're new to networking, these step-by-step instructions will allow you to organize a tournament with your friends in minutes.
Equipment check and basic network preparation
Before moving on to software settings, you need to make sure that your hardware is ready to transmit gaming traffic. Wireless network It's more susceptible to interference than a wired connection, so signal quality is critical. All computers or laptops participating in the game must be connected to the same router. It doesn't matter whether you use WiFi or a cable, as long as you share a single network.
Please pay attention to the WiFi standard your router supports. For comfortable gaming, it's important to have a range 5 GHz, which is less congested by neighboring networks and provides higher throughput. If your devices only operate in the 2.4 GHz band, try moving closer to the router to avoid packet loss, which can manifest as lag or character teleportation in games.
⚠️ Warning: Make sure that the "Power Saving" mode for the WiFi adapter is disabled on all devices, as the system may temporarily interrupt the connection to reduce power consumption, which will lead to a game crash.
It's also worth checking that all computers have the same game versions and required add-ons installed. Differences in client file versions are often the reason why players simply can't connect, even if the network is perfectly configured. Update your games ahead of time to avoid wasting time during the setup process.
Setting up sharing options in Windows
The most common barrier to creating a local network is the operating system's security settings. Windows hides your computer from detection by default, which is something you need to prevent. You need to go to the Control Panel and find the section responsible for network settings. Typically, the path looks like this: Control Panel → Network and Internet → Network and Sharing Center.
In the left pane of the window, select "Change advanced sharing settings." Here, you'll need to enable several key features. For the "Private" profile (or "Current profile"), enable network discovery and file and printer sharing. This will allow other computers to see your PC in the list of available devices.
Below, in the "All Networks" section, find "Password-protected sharing" and select "Turn off password-protected sharing." This will make connecting easier, as the system won't prompt each user for their username and password when attempting to connect. After making changes, be sure to click "Save Changes" for the settings to take effect.

It's important to understand that these settings only apply to the currently active network. If you connect to a public network (for example, at a coffee shop), Windows will automatically switch to the "Public" profile, where discovery will be blocked again. For home gaming, ensure the network is set to "Private."
Check IP addresses and workgroup name
For a successful connection, all computers must be on the same subnet and have unique IP addresses. Typically, the router automatically assigns addresses via DHCP, but sometimes it's useful to verify that the addresses are indeed correct. All addresses should begin the same way, for example, 192.168.1.X or 192.168.0.X, where X is a unique number for each device.
To check your IP address, open the command prompt by typing cmd in the Start menu and enter the command ipconfigFind the line "IPv4 Address." Also check the workgroup name: it should be the same on all computers. By default, in Windows, this is WORKGROUPYou can change this in the system properties.
| Parameter | Meaning of Computer 1 | Meaning of Computer 2 | Status |
|---|---|---|---|
| IP address | 192.168.1.15 | 192.168.1.20 | OK (different) |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | OK (same) |
| Gateway | 192.168.1.1 | 192.168.1.1 | OK (same) |
| Working group | WORKGROUP | WORKGROUP | OK (same) |
If you see that IP addresses start with different numbers (for example, one 192.168.0.5, and the other one 192.168.1.5), this means the devices are on different subnets and won't be able to connect directly. In this case, check your router settings or try reconnecting to the network.
⚠️ Note: Router and operating system interfaces may differ depending on the firmware version or Windows update. If you can't find this option, use the settings search or refer to your equipment manufacturer's documentation.
Setting up a firewall and antivirus
It often happens that the network is configured correctly, but the game does not see other computers due to blocking from the side Windows Firewall or a third-party antivirus. The security system perceives the connection attempt as a potential threat and blocks incoming connections. This needs to be corrected by adding an exception for your game.
Access your firewall settings via Control Panel and select "Allow an app or feature through Windows Defender Firewall." Click "Change settings" (requires administrator privileges) and find your game in the list. Make sure the checkboxes next to the game name are checked for both the "Private" and "Public" profiles.
If your game is not listed, click "Allow another app" and specify the path to the game's executable file (usually a file with the extension .exe). Users of third-party antivirus programs (Kaspersky, ESET, Avast, etc.) may need to temporarily disable "Network" mode or manually add the game to the exclusions list through the antivirus interface.
Launching the game and searching for servers
Once all the technical settings are complete, you can proceed directly to gameplay. Launch the game on all computers. In the menu, select "Network Game" or "Local Area Network" (LAN). On one of the computers, create a server (Create Game), selecting the map, mode, and number of players.
The remaining participants should select "Search for servers" or "Connect." If the server doesn't appear in the list automatically, try using the "Direct Connect" feature and enter the IP address of the host computer that you found earlier using the command ipconfigThis is the most reliable connection method.
Some older games may require you to manually enter the IP address in the configuration file or through the console. To do this, press the tilde key (~) in the game to open the console and enter the connection command, for example: connect 192.168.1.15Command syntax may vary depending on the game engine.
Optimizing WiFi to Reduce Ping
Playing over WiFi always carries the risk of connection instability compared to a cable. To minimize lag, try to free up some airtime. Close background programs that consume bandwidth on all devices, such as torrents, streaming services, and downloading updates. This will significantly reduce the load on your bandwidth.
If your router supports two bands, force all gaming devices to switch to 5 GHzThis range has more channels and is less susceptible to interference from household appliances like microwaves or Bluetooth devices. You can also set traffic priority (QoS) for gaming ports or MAC addresses of gaming PCs in your router settings.
⚠️ Important: Router placement matters. Don't hide it in a closed cabinet or behind a metal screen, as this will dramatically reduce signal quality and increase packet loss, which is critical for online shooters.
To diagnose connection quality, use the command ping in the command line. Enter ping 192.168.1.1 -t (replace with your router's IP address) and monitor the response time. It should be stable and low (less than 10-20 ms on a local network). Surges of 100 ms or more indicate signal problems.
☑️ Checklist before the match
Solving common connection problems
Even with proper configuration, specific errors may still occur. If computers can see each other, but the connection drops immediately after starting a game, the issue may be due to incompatible protocol versions or network card drivers. Update your WiFi adapter drivers from the manufacturer's official website.
Another common issue is IP address conflicts. If the router mistakenly assigns the same address to two devices, the network will not work. In this case, rebooting the router and all computers will help, forcing the DHCP server to reassign addresses. Also, try temporarily disabling IPv6 in the network adapter properties, leaving only IPv4 enabled, as some older games don't work well with the new protocol.
If all else fails, try creating a virtual local area network (VLAN) using special emulators (such as Hamachi or Radmin VPN), although this is overkill for gaming within a single apartment and can add unnecessary latency. It's better to focus on troubleshooting the standard Windows LAN.
Why can't computers see each other on the network?
Most likely, you don't have network discovery enabled in Windows, or the network status is set to "Public." Also, make sure your computer names are unique and the workgroup is the same. A firewall can also be hiding your PCs.
Is it possible to play via WiFi from different routers?
No, for classic LAN gaming, all devices must be connected to a single router. If the routers are connected via cable and configured as a single network (bridge or access point mode), gaming is possible, but it requires complex setup.
What ping is considered normal for WiFi gaming?
On a local network, the ping to the router should be less than 5 ms. Ideally, the ping between computers shouldn't exceed 10-15 ms. If the ping is higher than 50 ms internally, there may be signal issues or channel congestion.
Do you need internet to play on a local network?
No, an internet connection is not required. A local network runs within your hardware. However, an internet connection may be required to verify licenses for some modern games (DRM) or for voice communication if you don't use local alternatives.
