How to play Minecraft with a friend on PC over Wi-Fi: a complete guide from setting up a network to launching a server

Minecraft It's not just a game, but a whole world that becomes even more exciting when you can explore it with friends. But what if you want to play with two people over a local network? without purchasing a reality server or using third-party platforms? In this article, we'll look at how to organize a co-op game Wi-Fi between two computers - from setting up a router to launching your own server and solving common connection problems.

Many people mistakenly think that a paid server is required for a multiplayer game or Minecraft RealmsIn fact, if both players are on the same local network (for example, connected to the same router), you can create a server directly on one of the PCs and connect to it via LANThis method works for both Java Edition, and for Bedrock Edition, but with some nuances. We will focus on Java versions, as it offers more options for local hosting.

Important: If you've never set up a network or server before, don't worry—the process is simpler than it seems. Just follow the instructions and double-check each step. And if something goes wrong, you'll find solutions to the most common errors at the end of the article.

1. Preparation: What you need to play over Wi-Fi

Before you begin setting up, make sure you have everything you need:

• 🖥️ Two computers (or laptops) with the installed Minecraft Java Edition one version (for example, 1.20.4). Different versions of the game are incompatible!
• 📶 One Wi-Fi router to which both devices are connected. A wired connection can also be used (Ethernet), but in this article we focus on wireless networking.
• 🔌 A stable internet connection (not necessarily high-speed, but without frequent interruptions).
• ⚙️ Administrator rights on the PC that will host the server (to configure the firewall and ports).

If you have Bedrock Edition (Windows 10/11 version from the Microsoft Store), the connection process will be simpler, but there are limitations: for example, you can't use mods. In this case, simply open the world for LAN in the pause menu (Esc → "Settings" → "Multiplayer" → "Local Network"). However, for full control over the server (mods, plugins, world settings) it is better to use Java version.

Advice: Before you begin, make sure that VPN and proxy are disabled on both PCs—they may be blocking the local connection. Also, temporarily disable your antivirus (for example, Avast or Kaspersky), as it may block the game's network traffic.

2. Setting up a local network for Minecraft

For computers to "see" each other on the network, you need to make sure they're on the same subnet and aren't blocked by a firewall. Here's what to do:

1. Check the IP addresses of both PCs:
   • Click Win + R, enter cmd and run the command ipconfig.
   • Find the line IPv4 address - it must start with the same numbers (for example, 192.168.1.x). If the first three blocks are different (for example, 192.168.0.x And 192.168.1.x), this means that the PCs are connected to different networks.

Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings → Right-click on the active connection → Properties → Sharing tab → Uncheck "Allow other network users to connect to the network..."

Control Panel → Windows Firewall → Allow an application to interact with each other → Change settings → Find "Java(TM) Platform SE binary" and check the "Private" and "Public" boxes.

A critical detail: if you have a router with the "Client Isolation" feature, you need to disable it in the router settings. This feature blocks data exchange between devices on the same network.

3. Creating a local Minecraft server

The most reliable way to play over Wi-Fi is to run a server on one of the PCs. You don't need to download any separate software for this: Minecraft Java Edition There's a built-in feature for running a local server. Here's how:

• 🎮 On the host PC (the one that will be the server):
  1. Launch Minecraft and create a new world in the mode Creative or Survival.
  2. Open the pause menu (Esc) and select Open for LAN.
  3. In the window that appears, select the game mode (Creative, Survival, Adventure) and enable cheats if needed.
  4. Click "Run the world on a local network"A message with the port will appear (for example, 192.168.1.100:54321).

To connect to such a server, the second player must enter the IP address of the host PC (for example, 192.168.1.100) without port (used by default) 25565).

⚠️ Attention: If you have a weak PC (less than 4 GB of RAM), reduce the settings -Xmx And -Xms V start.bat to 512M, otherwise the server may slow down.

5. Configuring ports and forwarding on the router

If you are using a manual server (.jar), port forwarding may be required (port forwarding) so that the second player can connect. This is relevant if:

• You play through different networks (for example, one via Wi-Fi, the other via mobile Internet).
• The router is blocking incoming connections to the port. 25565.

How to set up port forwarding:

1. Go to your router's control panel (usually at 192.168.0.1 or 192.168.1.1).
2. Find the section Port forwarding (or "Port Forwarding", Virtual Servers).
3. Add a new rule:
   • Name: Minecraft
   • Port: 25565 (or another one if you changed it in server.properties)
   • Protocol: TCP/UDP (or both)
   • IP Address: Enter the local IP of the host PC (e.g. 192.168.1.100)

After this, the second player will be able to connect even from another network by entering external IP address your router (you can find it on the website whatismyipaddress.com). However, this method is less secure, as it allows access to your server from the Internet.

⚠️ Attention: If you are forwarding a port for access from the Internet, be sure to set up a password in server.properties (parameter enable-rcon=true And rcon.password=your_password) to prevent outsiders from connecting to your server.

6. Solving common connection problems

If the second player cannot connect to the server, please check the following:

• 🔌 "Failed to connect to server":
  • Please make sure you have entered the IP address correctly (no typos).
  • Check that the server (built-in or via .jar).
  • Disable firewall and antivirus software on both PCs.
• 🌐 "Server not responding" when connecting via external IP:
  • Check that the port 25565 forwarded on the router.
  • Make sure that your external IP has not changed (some providers have dynamic IP addresses).
  • Try connecting via local IP (if both are on the same network).
• ⚡ Lags and low FPS:
  • Reduce the number of mobs in server.properties (spawn-monsters=false).
  • Allocate less memory to the server start.bat (For example, -Xmx512M).
  • Close background programs that are consuming a lot of resources.

If nothing helps, try using Hamachi or ZeroTier These programs create a virtual local area network (VLAN) over the internet. However, they can increase ping, so it's best to use them only if other methods fail.

7. Server optimization for two-player games

To ensure smooth gameplay, even on low-end PCs, you can optimize the server:

• 📉 Reduce the draw distance:

  In the file server.properties install view-distance=4 (default 10). This will reduce the load on the processor.

• ⏳ Disable unnecessary mechanics:

  Add to server.properties:

  spawn-animals=false
  spawn-npcs=false
  spawn-monsters=false

  This will disable the spawning of animals, villagers and mobs.

• 🔄 Use PaperMC:

  PaperMC — is an optimized version of the Minecraft server that runs faster than the standard version. Download it from official website and replace the standard one .jar.

If you plan to play with mods, please install Forge or Fabric on both PCs and the server. Make sure the mod versions match, otherwise you'll get a connection error.
