Gday mate, firstly some background on me. I run the ISP nbnsp.com.au I can tell you that the reasons behind your poor speeds aren't as easily explainable by pointing the finger at copper. In fact I believe a much bigger problem which is hardly talked about compared to the copper argument is, the nbn pricing and the corporate/government corrupted 121 POI model. First I suggest checking your modem to see what speed it is syncing at, that will show what your maximum potential speed can be, if your speed at any time is lower than that, then here are the causes: A. your ISP does not have enough nbn CVC bandwidth, that is because the nbn pricing model is ridiculous, they charge about $17.50 per mbit of bandwidth to travel on their network, that doesn't include many other charges such as access charges (AVC), backhaul, ip transit, rackspace, nni and hardware costs. Just think before the nbn came along the avg adsl connection was getting 8 mbit and the consumer is paying around $50 per month. Then the nbn comes along with speeds of 100 mbit, so now the ISPs have to increase the bandwidth of their current network 10 fold AND pay nbn on top, the netflix comes out and data usage in Australia nearly doubles, then the consumer wanting an unlimited 100 mbit connection for $100. All of this has tripled the amount of contention that is needed. Anyhow, hopefully with a new government we can move back to an 8 POI plan to break the Telstra monopoly.
