When I first got my FTTP NBN line I was seeing some issues at around 9pm with speeds. (This was not long after the area was completed). Others in my location had similar issues - after about a week some adjustments were made by the ISP and I have been in 100/40 heaven for the last few years. It has been unbelievably reliable and there is no way I will settle for any other type of connection now

. The speed is rock solid.
Perhaps I am being a bit over the top, but I think it is a national shame what the Libs did to the NBN. No matter how good the wireless 4/5/6G technology gets, it is never going to beat the speed of light
