We went with TPG in the end after agreeing to waive CSG, this is detailed in another thread, and from when we ordered to when we were online with the NBN took 10 days. The internet is over FTTN and the VOIP phone was available the same day as the internet through them, so we are happy with that outcome.
I checked distance from the node to our house and speeds should be and are around 96 Mbps (Mega Bits Per Second) down and 37 Mbps up when at best but we do notice occasional drops to the point of no service 2 or 3 times a day.
The modem is their supplied HUAWEI Home Gateway HG659 with no external antennas for improving wifi signals or place/s to add them with AC version wifi , B (11 Mbps), G (54 Mbps), N (150 or 300 Mbps) are earlier versions of wifi standards with reduced max speeds and the modem does support these for older equipment. Most of our other wifi enabled equipment is N band using both 2.4 GHz and 5 GHz but we noticed the 5 GHz band from the modem is poor even in the same room as the other equipment and so most of our equipment reverts to the slower 2.4 GHz usage and so we get maximums around 150 Mbps. If you are going to get TPG FTTN I would suggest looking at perhaps another modem with external antennas to improve your wifi experience.
