Local area network (LAN) gaming is experiencing a renaissance, allowing friends to gather and immerse themselves in virtual worlds without the lag associated with the global internet. Modern operating systems, such as Windows 10, provide powerful built-in tools for connecting computers into a single infrastructure using a standard wireless connection. However, despite the apparent simplicity, the process often encounters barriers in the form of security settings and access profiles that block device discovery.
To successfully implement your plans, you'll need not only a stable router but also properly configured network settings on each client PC. Game servers, whether for classic shooters or real-time strategy games, require transparent data packet exchange between nodes. In this article, we'll walk you through each setup step in detail so you can focus on winning, not searching for missing servers.
The heart of the entire system is your wireless router, which acts as the central switch. It's important to understand that Wi-Fi Wi-Fi is inherently less stable than a wired connection, so properly prioritizing traffic and communication channels is critical to minimizing lag. We'll look at how to turn a regular home connection into a full-fledged gaming arena.
Equipment preparation and compatibility testing
Before moving on to software settings, you need to ensure that the physical base for your local network is ready to go. All computers participating in the game must be connected to the same wireless router. This means they must see the same access point. SSID and log in with the correct password. If one laptop is connected to the guest network and the other to the main network, they may end up on different subnets, making them invisible to each other.
Particular attention should be paid to the frequency range your router operates on. For gaming purposes, it is preferable to use the range 5 GHz, as it offers higher throughput and is less susceptible to interference from household appliances like microwaves or Bluetooth devices. However, if the distance between players is large, the 2.4 GHz band may be more stable, albeit slower.
⚠️ Important: Make sure Client Isolation (or AP Isolation) is disabled on your router. This security feature is designed to prevent devices on the same network from exchanging data, which completely blocks local gaming.
Also, check the wireless adapter drivers on all machines. Outdated software can cause intermittent connection drops or incorrect discovery protocols. It is recommended to download the latest driver versions from the official websites of network card manufacturers, whether Intel, Realtek or Qualcomm Atheros.
Setting up a shared network profile in Windows 10
operating system Windows 10 By default, it seeks to protect the user by assigning the "Public Network" profile to new connections. In this mode, the computer is hidden from detection by other devices, making it impossible to host a local game. The first step is to change this setting to "Private Network," which will open the necessary ports for local communication.
To do this, go to the Start menu and select the gear icon to open System Settings. Then follow the path Network and Internet → StatusIn the center of the screen, you'll see an image of your network and its connection status. Tap the name of your Wi-Fi connection to open its properties.
In the window that opens, under the "Network Profile" heading, switch the radio button from "Public" to "Private." This action signals the system that you are in a trusted environment and allows protocols. SMB And NetBIOS to function fully. Without this step, the computers simply won't see each other in the list of available nodes.
☑️ Check your network profile
After changing your profile, the system may ask you to confirm whether your PC will be discovered on the network. Accept this request. Your machine is now ready for more detailed sharing settings, which will be discussed in the next section. Remember, this procedure must be repeated on each computer you plan to use for gaming.
Enable network discovery and sharing
Even with the correct network profile, discovery services may be disabled in the advanced settings. To enable them, open the Control Panel (the classic one, not the new Settings menu) and go to Network and Internet → Network and Sharing CenterIn the left column, select "Change sharing options."
A list of profiles will open. Make sure you're in the "Private (Current Profile)" section. Here, you'll need to enable the following options:
- 📡 Turn on network discovery (and check the box "Turn on automatic configuration of connected devices").
- 📁 Enable file and printer sharing.
- 🔐 Allow management of HomeGroup connections (if available).
Next, expand the "All Networks" section at the bottom of the window. Here, it's crucial to find the "Password-protected sharing" setting and toggle it to "Turn off password-protected sharing." This will allow players to connect to the game host without having to enter their Windows account login and password each time they try to connect.
⚠️ Important: Disabling password protection is only allowed on a trusted home network. If you're in a public place or office, leaving ports open without authorization creates a risk of unauthorized access to your files.
Be sure to click the "Save Changes" button at the bottom of the page. Afterward, it's recommended to restart your computer so that all network services are restarted with the new configurations. Basic network visibility should now be ensured.
Configuring Firewall Rules for Games
Built-in protector Windows Defender Firewall Often becomes the main obstacle to local multiplayer, blocking incoming connections from other players. Even if the network is configured perfectly, the firewall may consider game packets suspicious and discard them. We need to create an exception for a specific game or for the entire private range.
Open the Start menu, type "Firewall," and launch the Windows Defender Firewall app. In the left menu, select "Allow an app or feature through firewall." Click "Change settings" (requires administrator rights), then "Allow another app."
In the window that opens, click Browse and find the executable file of your game (usually with the extension .exe). Add it to the list and make sure the "Private" and, if necessary, "Public" boxes are checked. If you don't want to search each file individually, you can temporarily allow all traffic for private networks, but this is less secure.
| Parameter | Recommended value | Impact on the game |
|---|---|---|
| Network profile | Private network | Opens discovery ports |
| General access | On | Allows data exchange |
| Password protection | Disabled | Simplifies connection (LAN) |
| Firewall | Exception for the game | Skips game packets |
For advanced users, there is the option to customize rules through "Advanced Options." Here you can create an inbound rule for a specific UDP/TCP The port the game uses. This information can usually be found in the game's technical documentation or on community forums.
Which ports are most often blocked?
Most often, problems arise with dynamic ports or ports used for LAN browsing (for example, UDP 17777 for some shooters or Steam ports for transmitting server data). Blocking these ports results in the server appearing in the list, but the connection to it being dropped.
Creating a network and connecting players
Once all the preparatory steps are complete, the moment of truth arrives: launching the game. One of the computers must act as the host (server). In the game menu, select "Create Game" or "Local Area Network" (LAN). It's important to select "LAN" in the game settings, not "Internet," if the game supports both modes.
The remaining participants should launch the game and go to "Network Play" → "LAN." Ideally, the created server will appear in the list of available servers within a few seconds. If the server doesn't appear automatically, use the "Direct Connect" feature and enter IP address host computer.
To find out the IP address of the host, on the server computer, click Win + R, enter cmd and in the black console window, type the command:
ipconfigYou need the "IPv4 address" line, which usually looks like this: 192.168.1.XX or 192.168.0.XXThis is the address that needs to be communicated to other players for direct access.
⚠️ Please note: IP addresses assigned by your router may change when devices reboot (dynamic addressing). If you plan to play regularly, it may be a good idea to assign an IP address to the host network card in your router settings or manually enter a static IP address in the Windows adapter properties.
Make sure the game version and all installed modifications (mods, maps, patches) are identical on all computers. Even the slightest discrepancy in file versions can cause connection errors or a game crash immediately after the match starts.
Optimizing and troubleshooting ping issues
If the connection is established, but the game is experiencing stuttering (lag) or high ping, the problem lies in the quality of the wireless signal. Wi-Fi is susceptible to interference, and for a gaming local network, stability is more important than maximum download speed. Try moving the router to a more central location relative to all players or using Wi-Fi repeater to enhance the signal in the playing area.
Close all background applications that consume bandwidth, such as torrents, cloud syncing apps, and streaming services. Even if you're playing on a local network, overloading your Wi-Fi connection with downloads can cause packet loss, which is critical for first-person shooters.
- 🚀 Update your router firmware to the latest version available on the manufacturer's website.
- 📡 Switch the Wi-Fi channel in your router settings to a less busy one (use Wi-Fi analyzer apps on your smartphone).
- 💻 Disable power saving for the network adapter in Windows Device Manager while playing.
In some cases, resetting the TCP/IP stack can help. Open the command prompt as administrator and enter the command netsh int ip reset, then restart your computer. This will reset Windows network settings to factory defaults, eliminating any possible software conflicts.
Frequently Asked Questions (FAQ)
Why can computers see each other on the "Network", but the game can't find the server?
Most likely, the blocking occurs at the Windows Firewall or antivirus level. Check if the game app is added to the exceptions list. Also, make sure the same version of the game is installed on all PCs.
Is it possible to create a local network if one PC is connected via cable and the other via Wi-Fi?
Yes, this is possible if both devices are connected to the same router and are on the same subnet. However, the router must correctly route traffic between the wired and wireless segments, which is usually enabled by default.
How to reduce ping on a local network via Wi-Fi?
Use the 5GHz band, move your devices away from sources of interference (microwaves, baby monitors), close background downloads, and, if possible, use a cable to connect to the game host.
Do you need internet to play on a local network?
No, an internet connection is not required. Your local network runs within your hardware. However, an internet connection may be required to verify DRM licenses for some modern games or to download maps if they are not installed locally.
