If you find that the Optical Light on your Lightstream Fibre ONT (Optical Network Terminal) box is flashing, has gone off or has gone red, this means there may be an issue with the fibre connection coming into your property.
What can I do?
First, please check that the optical cable which comes through your wall into the ONT hasn't become loose. If it has, try pushing the end into the ONT to make sure it's clicked all the way in. Now turn the ONT off and on again from the main socket on the wall.
