Apologies that you have been faced with difficulties with the connection. I've ran initial tests and have detected some drop outs as well. We will need to perform troubleshooting along with you to determine any underlying cause.
Could you please send us with your best call back number via private message as well as your most convenient time to receive a call so we can organise a contact to be made from our Technical team?
Based on the results of the tests we've performed over the last 2 days, we're able to detect that your NBN box is losing connection. We have just refreshed the connection to see if that would help. That being said, I have escalated this issue to our Engineering Team for possibly raising it to NBNCo if the refresh on the NBN box doesn't fix the issue. You will be contacted through SMS or phone call for the updates about the case.
If you have other concerns or questions, feel free to leave a comment.
