Part 1: Unboxing and Physical Setup (Do This First)

Before touching any software, ensure your physical hardware is correct. A staggering 40% of "setup failed" errors are due to loose cables.

Step-by-Step Physical Connection

Position the router: Place it in a central, elevated location—not inside a cabinet or near a microwave.
Attach antennas: Screw each antenna clockwise until snug. Angle them at 45 degrees outward for omnidirectional coverage.
Connect to modem: Take the yellow Ethernet cable. Plug one end into your ISP modem’s LAN port (or Ethernet port). Plug the other end into the KJ33’s WAN port (usually colored blue and labeled "Internet").
Power up: Connect the power adapter. Wait 60-90 seconds. The power LED should become solid green. If it blinks red, check the outlet.

Critical: Do NOT connect the router to your computer via Ethernet yet. We’ll do that after the router initializes.

Disable Remote Management

Under Security > Remote Management, set to "Disabled" . This prevents hackers from logging into your router from the internet.
