Fibre: How to connect your router to the ONT and the internet

This article is designed to help you get internet up and running once your Lightwire router arrives at your home.


  1. Unbox your router and connect one end of the supplied ethernet cable to the blue WAN port on the back of the Huawei router and the other end to the blue 10G LAN port of the Comtrend ONT.

    Make sure the power adapters to the router and ONT are plugged in and turned on at the wall.

  2. The ONT will take a few minutes to connect to the internet. Once done, this will be signaled by the green PON & internet lights. From here everything is connected as it should be.ontDOC1.png


Connecting the router to the internet


  1. Your router needs to register onto the Lightwire network before you can access the internet. This will take approximately 10 minutes and the router will restart twice. Do not turn off the equipment during this process.

  2. Once you see your “Lightwire” Wi-Fi name appear on your phone or other device, use the password provided (or call us on 0800 12 13 14) to connect to the Wi-Fi. You should now be able to access the internet.

To change your Wi-Fi name and password please get in touch with our help desk on 0800 12 13 14.


If you are having trouble, please call us and we can arrange for a technician to meet you on site.



Please do not remove any of the fibre cables. Leave the equipment turned on.
