I thought I should post this to give people hope... we have HFC NBN (Cable) in Seaforth NSW.
Happily after a week and a half of no internet after our NBN migration and after finally after managing to extract an NBN tech onsite appointment for tomorrow afternoon. Suddenly our internet came good, with high speeds (as advertised... or close). I had tried everything, resetting NBN and Sagemcom 3864AC as instructed, calling tech support multiple times!
In the end I rigged up a test script to timestamp a continual ping test of the Optus Gateway 18.104.22.168. It showed roughly 35% packet loss, this was why our internet was broken.
Looking at the log they started fiddling around at 10:40am this morning with suddenly the connection no longer dropping packets but with very poor ping response times for about an hour e.g.

Prior to this I was seeing on average 35% packet loss, which basically meant the internet was unusable. Then after roughly an hour at 11:50 the connection dropped and things went back to horrible 35% loss again.

Then amazlingly (praise the internet gods!) at 1:37pm the NBN/Optus connection cleaned up and I started getting fast ping response times and no packet loss:

The speeds test pretty good 80 Mbps download, using WIFI close to the modem, it will probably get >90 Mbps direct to NBN modem.
I don't know who did what, if it was Optus or NBN, or indeed if it will stay good, but I know the problem was not my local line or NBN modem!
I've not heard anything so will keep the NBN tech visit for tomorrow, the lack of visibility and accountability is the real killer. In this day and age it would not be hard to provide a mechanism for the engineers/techs to give visibility to their clients.
Fingers crossed it all doesn't turn to poo again.

This is a known issue for NBN HFC connections ordered on the NBN systems between 26th October and the 6th November.
Did Optus not tell you about the problem.
NBN have been progressivly fixing the affected services. Once fixed they stay fixed as it was originally a provisioning configuration error in the NBN system.

No Optus did not tell me about this “known issue”.
All part of the special “Optus” custome service guess. Their tech support ppl o spoke with had no idea.

How do you know about this known NBN HFC config issue?

There's a long thread on Whirlpool, under the Aussie Broadband section but it affected all RSPs.
Go a few pages intoi the discussion before the issue really started to crystalise.

Thanks for the info.
To be honest I'm really annoyed that Optus Support failed to pass this information on. I'll ask the NBN tech who is comming tomorrow afternoon if he knows anything about it.
