Game of Minecraft is often associated with endless worlds and online interaction, but what if the internet suddenly goes down or is completely unavailable? Many users mistakenly believe that multiplayer mode is impossible without an active internet connection. In fact, the game offers powerful tools for organizing local play, allowing you to connect computers into a single network even without access to a Wi-Fi router.
The essence of the method is to create LAN (Local Area Network) or direct connection between devices. In this case, your computer or laptop acts as a server, handling the world's physics and player interactions. This is ideal for playing in a shared apartment, office, or camp without an external network connection, but want to build a shared house or host a PvP tournament with friends.
In this article, we'll cover all the technical details, from setting up static IP addresses to port forwarding in Windows Firewall. You'll learn how to transform a group of disparate laptops into a unified gaming ecosystem. The key requirement is a physical connection between devices via an Ethernet cable or the creation of a virtual bridge, as without any network environment, data transfer is impossible.
Equipment preparation and network infrastructure
The first step is to understand the physical topology of your future network. If you have a router, but it's not connected to your ISP (no internet) but distributes local IP addresses, this is ideal. All devices connect to it via cables or Wi-Fi, and the game runs smoothly. However, if you don't have a router at all, you'll need to create a direct peer-to-peer network.
To directly connect two or more PCs, you'll need Ethernet cables (twisted pair). Modern network cards automatically detect the cable type, so there's no need to look for special crossover cables. If you have more than two devices and don't have a router, you'll need a network switch to consolidate all the cables into a single structure.
- 🔌 Ethernet cables long enough to connect all game participants.
- 💻 Devices (PCs or laptops) with working RJ-45 network ports.
- 🔀 Network switch if there are more than two players and there is no router.
- ⚙️ An installed and active network card on each computer.
⚠️ Note: When connecting two computers directly without a router or switch, the operating system may not assign an IP address automatically. In this case, manually setting static addresses is required for the TCP/IP protocol to function correctly.
It's important to ensure that the network adapters are working properly. The port lights should blink, indicating physical contact. If the lights are on but there's no connection, the problem lies in Windows software settings or network card drivers.
Setting up static IP addresses in Windows
For a local Minecraft server to function smoothly, all computers must be on the same subnet. If you don't have a DHCP server (usually found in your router), you'll have to manually enter addresses. This will prevent conflicts and allow devices to "see" each other.
Go to network settings. To do this, click Win + R and enter the command ncpa.cplFind your connection (usually "Ethernet" or "Local Area Connection"), right-click and select "Properties." Find the protocol in the list. Internet Protocol version 4 (TCP/IPv4) and open its properties.
Here you need to enter static data. For the first computer (server host), use the address 192.168.0.1, for the second - 192.168.0.2 and so on. Set the subnet mask to the default one. 255.255.255.0The gateway and DNS can be left blank or the host address can be duplicated, since there is no internet access anyway.
☑️ Check network settings
After setting up the addresses, test the connection. Open the command prompt (cmd) and enter the command ping 192.168.0.2 (where the second address is your friend's IP address). If you see the response "Reply from...," then the physical and logical layers of the network are configured correctly.
Running a local server in Minecraft
Now let's move on to the game itself. Launch Minecraft on the computer that will act as the server (host). Enter single-player mode, create a new world, or select an existing one. It's important that all computers are running the same version of the game, including patch numbers.
While in the world, press the key Esc to exit to the pause menu. From the list of available options, select the button Open in LAN (Open to LAN). A settings window will appear where you can select a game mode (Survival, Creative) and allow or prohibit cheats for other players.
After confirming the action, a message will appear in the chat: “Local game hosted on port XXXXX”. Write down this port number, it is critical for connecting other participants. By default, Minecraft often uses the port 25565, but when opening a world in LAN it may be random.
What should I do if the "Open in LAN" button is grayed out?
If the option is unavailable, make sure you're in the game world and not the main menu. Also, check if the game is running in offline mode with restrictions. Sometimes restarting the launcher with administrator privileges helps.
The server host must remain logged in at all times. If the world host exits to the main menu or closes the game, the local server will immediately shut down and all other players will be disconnected.
Connecting clients and entering the game
On other computers (clients), the process is different. They don't need to create worlds. Simply launch Minecraft, go to the main menu, and select Network game (Multiplayer). The game will automatically scan your local network and, if everything is configured correctly, display an available server in the list below.
If the automatic search does not yield results, use a manual connection. Click the button Add a server or Direct connectionIn the server address field, enter the IP address of the host computer. The format is as follows: 192.168.0.1:25565, where the first part is the host IP and the second is the port you wrote down earlier.
| Parameter | Value for Host | Value for Client 1 | Value for Client 2 |
|---|---|---|---|
| IP address | 192.168.0.1 | 192.168.0.2 | 192.168.0.3 |
| Subnet mask | 255.255.255.0 | 255.255.255.0 | 255.255.255.0 |
| Port of the game | 25565 (example) | 25565 (input) | 25565 (input) |
| Role | Creator of the world | Player | Player |
Once successfully connected, you'll find yourself in a shared world. Lag (delay) on such a network is usually minimal, as data is transmitted directly over the cable, bypassing external communication channels. However, the host's performance directly impacts the smoothness of the game for everyone.
Troubleshooting Firewall and Antivirus Issues
The most common reason why friends can't see the server or connect is Windows' built-in firewall. By default, the firewall treats a new local network as "Public" and blocks incoming connections for security reasons.
You need to add an exception for Java. Open Control Panel → Windows Defender Firewall → Allow an app. Find it in the list. Java(TM) Platform SE binary or javaw.exeMake sure both the private and public network boxes are checked.
If manual configuration seems complicated, you can use the command prompt with administrator rights. Enter the following command to create a rule allowing incoming traffic to the game's port:
netsh advfirewall firewall add rule name="Minecraft Server" dir=in action=allow protocol=TCP localport=25565After applying the changes, it's recommended to restart the game. Also, check your network profile. In Windows 10/11, switch the network type from "Public" to "Private" in the Ethernet settings; this will remove many device discovery restrictions.
Alternative methods: virtual networks
If it is not possible to physically connect computers with cables (for example, they are in different rooms far from each other, and there is no Wi-Fi router), you can use software local area network emulators. Programs like Hamachi, Radmin VPN or ZeroTier create a virtual network adapter.
These programs require a one-time internet connection for installation and initial authorization, but once configured, they can run in the background, allowing you to play Minecraft as if it were a regular local network. All participants must install the same software and log into the same virtual room.
The advantage of such solutions is that they bypass complex IP address and firewall configurations by creating a tunnel between devices. However, performance may be lower due to the overhead of traffic encryption and virtual driver processing.
⚠️ Note: Virtual networking software interfaces (Hamachi, Radmin) and driver versions may be updated. Always check the latest port settings and firewall rules in the official documentation of the software developers.
Using virtual networks is especially relevant if you do not have a network switch, but have the ability to connect PCs through a single host computer acting as a gateway, although this requires a more in-depth knowledge of network architecture.
Frequently Asked Questions (FAQ)
Is it possible to play via Wi-Fi adapters without a router?
Yes, Windows has a feature called "Mobile Hotspot" or ad-hoc networking. One laptop distributes Wi-Fi, and the other connects to it. However, the speed and stability of such a connection are often inferior to a wired connection, which can cause lag in Minecraft.
Do I need a licensed Microsoft account to play on LAN?
A license isn't always required for playing on a local network if a pirated version with the same nickname is used (although this may cause name conflicts). However, modern versions of launchers and servers require unique nicknames. Official servers require a license, but a purely local world will run on illegal copies if configured correctly.
Why does the game crash when a second player connects?
Most often, this is due to a lack of RAM on the host computer. The Minecraft server is quite resource-intensive. Try reducing the chunk draw distance in the video settings or allocating more memory to Java in the launch options.
How to transfer mods to other players without internet?
All mods, textures, and configurations must be identical on all PCs. Copy the folder mods And config from the game directory on the host computer to a USB drive, and then transfer them to the game folders on your friends' computers. The Forge or Fabric versions must also match.
