So sorry to hear you have same problem KleskReaver like many of us have. No, I am FTTP and I have now resourced all avenues and being fobbed around by Manilla - Technical Support, Billing, Case Manager and Complaints with no end in sight and no answer as to when it will be fixed. Just the meaningless answer to me of "sorry, cannot give you a scheduled time as to when it will be fixed but has been escalated with Technical Support and they are currently working on it."
Simple, solution is as I mentioned above in the original post re all RSP's with this Speed Slowness problem. Bottom line, RSP's, stop shortfalling/scrimping in bandwidth purchasing from the NBN Company and provide Customers with the correct Speeds as stipulated within your Package Plan (CVC and other charging). I know we have currently 600 Users in our area on NBN. NBN went live in our area nearly 3 weeks ago. I am in Runcorn, Queensland.
I have now written to the Telecommunications Ombundsman demanding they try and fix this HUGE National problem. Also mentioned to them that they are refusing to let me go back to my reliable fast Cable Internet due to Terms and Conditions with NBN. My argument is they have breached my Terms and Conditions as a Customer upon signing up when I did not have to and the CVC Conjestion problem was already there (disgusting Sales tactics). I had 12 to 18 months to which I could of still stayed on my fast reliable Telstra Cable with always awesome Internet Speeds as I posted above.
Below is a photo of my current Speed and I too on the 100/40 - disgusting...
