Welcome to the Community!
I can see that your modem is already connected and working. Although, it seems that you spoke to our Helpdesk yesterday as well. A ticket has been escalated to our Engineering Team for a speed issue.
And though your modem is already getting a good speed, I suggest that you wait for further update from our Engineering Team since your modem has experienced several dropouts over the last 24 hours. Based on our records, an SMS was already sent advising you as to when Telstra can check your line. Feedback pertaining to the outcome of the Telstra repair will be given to you by the assigned Case Engineer.
