Hi @akhilsivanss
Thanks for reaching out to us. We understand how frustrating it is not to have a working internet service, and we sincerely apologize for the inconvenience.
A flashing downstream light usually means the connection is still being established. If the online light is on, it's likely the NBN box is undergoing a firmware upgrade. In the meantime, please try turning off your NBN box for 30 seconds, then switching it back on.
If the issue continues, feel free to contact us on 131245 or via our live chat platform - our team is ready to help.
Warm regards, Sheena
