I switched to NBN50 yesterday (been with TPG for nearly 6 years), hopefully the speed would improve. But unfortunately no, it frustrated me that the speed really inconsistant for the last 1 year. Especially at night after 8pm, I couldn't do any basic web surf or watch videos on my laptop. If this doesn't solve probably, I consider to change another provider
