When I went from Optus cable to NBN which is my old foxtel (Telstra) cable I suffered odd dropouts and slow internet speeds sometimes lose the internet for day or so.
My carrier Optus & NBN techs would stuff around doing online checks saying nothing wrong with the system but would concede the odd dropouts with no resolution to the problem.
This went on for a year or two then one day my neighbour was getting his foxtel upgraded which required onsite technician and after talking to him about my experience; this tech had my problem solved in half hour by simply changing the coaxial fittings on the house, lamp post and street pit box.
He said this a common problem plaguing older systems switched over to NBN. To this day my NBN has been great to use.
