How do I connect the Ethernet cables for my HUAWEI WiFi WS5200?
  1. Connect one end of an Ethernet cable to the blue port (WAN port) on the router and connect the other end to an Extranet.
  2. Connect one end of an Ethernet cable to the gray port (LAN port) on the router and connect the other end to the computer.

    If you want to configure your router wirelessly on a laptop, tablet, or phone, you do not need to connect the router to a computer with an Ethernet cable.

  3. Connect the power adapter to the router.
