I recently changed to TPG superfast NBN100 and should be getting speeds between 30-71mb/s according to the official website. First I couldn't even connect to the internet and just had an NBN technician fix that for me, but we are getting an average speed of 15mb/s. I have tried changing the channel through tp-link but this made no difference or decreased the speed.
This is unacceptable, especially since when I am paying for the faster connection. The top speed I got with Telstra was 20mb/s, but it kept dropping out so I changed to TPG. Could this be a problem with the NBN line itself?
NBN FTTN comes into your premise via telephone cables. The sync speed of this product is directly related to the distance you are from the Node. If you are too far from the Node then you will never obtain the speeds that you are after. Its a physical limitation and cannot be overcome. The other possibility is that you have a fault with your line. It seems from reading your post that you have had the same issues with another carrier.
I can see that your modem is syncing at 17.88 Mbps so there is no point in trying to improve your Wifi as it is operating Ok.
I will wait for your response.
