Setup Instructions
Follow these steps to set up your Comtrend G.hn Powerline network:
- Connect the First Adapter: Plug one PG-9172PT adapter into a wall outlet near your internet router. Avoid power strips or surge protectors, as they can interfere with powerline performance.
- Connect to Router: Use an Ethernet cable to connect the adapter's Ethernet port to an available LAN port on your internet router.
- Connect the Second Adapter: Plug the second PG-9172PT adapter into a wall outlet in the room where you need network access.
- Connect Network Device: Use an Ethernet cable to connect the second adapter's Ethernet port to your network device (e.g., computer, smart TV, game console).
- Verify Connection: Wait for the Powerline LED on both adapters to turn solid green, indicating a successful connection. If the LED is amber or red, the connection quality may be lower. If it's off, there's no connection.
- Secure Pairing (Optional but Recommended): For enhanced security, press the Pair button on the first adapter for 2 seconds. Within 2 minutes, press the Pair button on the second adapter for 2 seconds. The Powerline LEDs will flash during pairing and become solid when successful.
