When wiring an Ethernet cable with an RJ45 connector, it's crucial to follow the correct color code to ensure a stable and functional network connection. The two most common standards are T568A and T568B. T568A follows the order: Green/White, Green, Orange/White, Blue, Blue/White, Orange, Brown/White, Brown. T568B follows the order: Orange/White, Orange, Green/White, Blue, Blue/White, Green, Brown/White, Brown. Choose one standard and consistently use it throughout your network.
