Welcome to the community!
I'd love to help and see what is happening on your connection. I'd like to know on which device(s) you experience a slow connection? Have you tried to run a speed test? If yes kindly post the result on this thread.
Thanks for raising this to us. We ran an initial test on your connection and it shows multiple dropouts and a possible line fault on the line.
We would like to confirm if you are also having issues with the home phone service like static noise or no dial tone. If so, please raise this to Telstra to check the line as it affects your Standalone ADSL2+
We'll wait for your response, let us know how it will go.
Thanks for getting back to us. We ran an initial test to your service and it shows a possible internal cabling causing dropouts and no connection network to your service.
We would like to arrange a call from one of our Technicians for real-time testing and investigation, feel free to PM me your best contact number and preferred time.
Thanks for sending me your details. I arranged one of our Technicians to call you tomorrow between 10-12NN AEST.
Make sure to keep your mobile phone available for the call and let us know how it will go.
