D-Link DSL-2888A Slow TPG NBN FTTN Connection

[simonlina]

I just bought the D-Link DSL-2888A, got it connect working with TPG NBN 50 plan but getting very slow speeds. 
speedtest.net shows around 5mbps download speeds. Is there something additional I need with my settings or is this modem/router not compatiable?
I connect the standard huawei modem HG659 back on getting 20mbps download speeds, still slow for the NBN 50 plan considering I'm only about 600m from the node on the FTTN connection.
