Cara Membuat Jaringan LAN Sendiri

Introduction

This tutorial will guide you through the process of setting up a Local Area Network (LAN) in your home or office without internet connectivity. By the end, you'll have a functional network connecting multiple computers, enabling file sharing and communication between devices.

Step 1: Gather Required Equipment

To build your LAN, you will need the following equipment:

• Computer(s) to connect
• Switch (with a sufficient number of ports for your computers)
• UTP (Unshielded Twisted Pair) cables
• RJ-45 connectors
• LAN Tester or Cable Tester

Step 2: Create UTP Straight Cables

1. Cut the UTP cable to the desired length for each connection.
2. Strip off about an inch of the outer insulation from both ends of the cable.
3. Untwist the pairs of wires and arrange them according to the T568B standard:
   • Pin 1: White/Orange
   • Pin 2: Orange
   • Pin 3: White/Green
   • Pin 4: Blue
   • Pin 5: White/Blue
   • Pin 6: Green
   • Pin 7: White/Brown
   • Pin 8: Brown
4. Insert the wires into the RJ-45 connector, ensuring they reach the end.
5. Use a crimping tool to secure the connector to the cable.

Step 3: Test the Cable Connections

1. Use the LAN Tester to check the newly created cables.
2. Connect one end of the cable to the tester and the other end to the appropriate port.
3. Ensure the tester lights indicate a successful connection for each wire.

Step 4: Connect Computers to the Switch

1. Plug one end of each UTP cable into the LAN port of each computer.
2. Connect the other end of the cables into the switch ports.

Step 5: Configure IP Addresses

1. Go to the network settings on each computer.
2. Choose to set IP addresses either statically or automatically (via DHCP):
   • For static IP:
     • Assign a unique IP address to each computer (e.g., 192.168.1.2, 192.168.1.3, etc.).
     • Use a subnet mask of 255.255.255.0.
   • For automatic IP:
     • Enable DHCP on the switch if supported.
3. Ensure all computers are on the same subnet.

Step 6: Check the Network Connection

1. Open the command prompt on each computer.
2. Type ping followed by the IP address of another computer in the network (e.g., ping 192.168.1.3).
3. Ensure you receive replies indicating successful communication.

Conclusion

You have successfully set up a LAN that connects multiple computers without the need for internet access. This setup is ideal for local file sharing and communication. For future enhancements, consider setting up a network with internet connectivity, which will be covered in the next tutorial.
