The Optical Network Terminal (ONT)

This device is your Optical Network Terminal (ONT). It connects the modem supplied by your broadband provider to the Chorus fibre network.

The ONT belongs to Chorus and if you move you should leave it in this property for the next resident or tenant.

If the lights of your modem aren't on check it is plugged in properly and the rest of the house has power

What to do if your optical network terminal is not working.

If you are having problems with your internet connection you should ring your broadband provider and report a fault. Your broadband provider will contact Chorus if they believe a technician's visit is necessary to fix the fault.

Your ONT is an electronic device and it needs to be connected to a power supply. If the lights are off check that it is plugged in and there is power in the property

The problem could be with our equipment in the exchange, the ONT, or the modem supplied by your broadband provider. The lights on the ONT may give you some indication of what the issue is. Turning your ONT off and on is unlikely to fix the problem.
