This is the problem description for TIO complaint 2019/12/02636,
  since the form doesn't accept the entire text.

This complaint relates to the NBN fixed wireless “service” in Dereel,
which I have been using since December 2013.  It is the only Internet
service available, and the reliability is the worst I have experienced
in 30 years using the Internet.  I first noticed this problem in June
2014 (http://www.lemis.com/grog/diary-jun2014.php#D-20140607-015618).

Most of the unreliability comes from NBN “scheduled maintenance”,
which they have been performing on a regular basis for several years
now, causing regular outages of up to 8 hours during the daytime,
effectively taking the service offline for a whole day (for example,
from 17 October 2019 08:38:34 to 17 October 2019 16:29:26).  Since
August 2016 I have received a total of 81 outage notifications from my
RSP, and there have been some for which I have not been informed, such
as on 23 April 2018
(http://www.lemis.com/grog/diary-apr2018.php#D-20180424-001301).  I
have a complete list of outages at
http://www.lemis.com/grog/nbnstats.php which currently shows a total
of 418 outages amounting to 11 days, 6½ hours.

The first time I complained was on 13 April 2018
(http://www.lemis.com/grog/diary-apr2018.php#D-20180414-015333), when
I was told that these outages were necessary to improve service in the
future.  But they have been continuing for over 2 years now, and there
are always new outages on the horizon.  Both the frequency and
duration of the outages are on the increase.  For the months of July
2019 to October 2019 there were a total of nearly 39 hours of outages,
an availability of only 98.52%, or an average of 26 minutes of
downtime every day.  Currently (6 December 2019) there are three
outages scheduled for the next 2 weeks, covering a time frame of 12
days, and with potential outage durations of up to 12 hours.  I can't
recall a time when there has not been at least one outage scheduled.

I lodged a formal complaint with Aussie Broadband on 3 July 2019
(http://www.lemis.com/grog/diary-jul2019.php#D-20190704-050320), when
I was told to expect a call back from the NBN within 1 to 2 weeks,
with the fault number #6275739.  I didn't hear back.

On 14 November 2019 I checked the progress of the fault number, and
couldn't find it.  I contacted Aussie Broadband repeatedly, but did
not get an explanation for the disappearance of the fault.  Instead
they raised a new complaint with the NBN, #11411861.  I asked for a
response by CoB 29 November.  So far I have had no contact.

I find this level of service completely unacceptable.  While I
appreciate that it's not possible to maintain 100% reliability, I find
that the current situation is not even close to reliable.  If I had an
alternative, I would probably take it.  As a state-sponsored
monopolist, I consider that the NBN has a responsibility to improve
its services.  There is a Telstra mobile phone tower next to the NBN
tower.  It uses very similar technology, and I haven't heard of any
outages with it.
