Simple Computer Network Setup

Introduction

• Objective: Connect a MacBook to a Windows desktop using an Ethernet cable.
• Focus on networking settings for both operating systems.
• Applicable for multiple computers of the same type (Mac or Windows).

Hardware Required

• Computers:
  • 1 MacBook
  • 1 Windows Desktop
• Network Switch:
  • Many home wireless routers have built-in switches.
  • Look for yellow Ethernet ports on the router to create a Local Area Network (LAN).
• Ethernet Cable (Patch Cable):
  • Can be purchased or made.
  • Use either CAT5 or CAT6.
• Adapter for MacBook:
  • USB-C to Ethernet converter (if MacBook lacks Ethernet port).
• Wireless Router:
  • Ensure to use the LAN ports (1-4) and not the internet port.

Connecting the Devices

1. Connect one end of the Ethernet cable to the MacBook adapter.
2. Connect the other end to an available port on the router.
3. Repeat the process for the Windows desktop.
4. Observe blinking LEDs on the router indicating successful connection.

Configuring the Network

Windows Configuration

1. Go to Settings from the Start menu.
2. Navigate to Network and Internet.
3. Select Ethernet and then Properties.
4. Ensure IPv4 is set to DHCP (Automatic IP).
   • If not, edit the setting to select DHCP.

Mac Configuration

1. Go to System Preferences and select Network.
2. Identify the USB-C connector (not labeled as Ethernet).
3. Confirm that an IP address is assigned (e.g., 192.168.1.32).

Testing Connectivity

Ping Test

• Ping Windows from Mac:
  • Open Terminal on Mac.
  • Type ping <Windows_IP_Address> (e.g., 192.168.1.29).
  • Note: Initial ping may fail due to Windows security settings.
• Enable Network Discovery on Windows:
  1. Go to Settings.
  2. Select Network and Internet.
  3. Go to Advanced network settings.
  4. Enable Network discovery and File and printer sharing.
• Ping Mac from Windows:
  • Open Command Prompt.
  • Type ping <Mac_IP_Address>.

Conclusion

• Both computers should now be able to ping each other, confirming successful connectivity.
• Network is ready for file sharing or gaming.
