interesting report published by the ACMA today regarding typical NBN compatible modem performance. https://acma.gov.au/theACMA/get-the-right-modem-for-peak-nbn-performance the good bits are in the full report linked on this page. https://acma.gov.au/theACMA/nbn-wi-fi-modem-study some of the numbers in table 2 are an eye opener. DSL sync speeds on a standardised line can vary considerably, and look at the variance on a line with real-world noise; the Billion BIPAC8900X tolerated some noise very well, but other modems like the Netcomm AC1600 NF18ACV showed a great deal of varation in tolerance which I suspect will be due to firmware version, whereas others just sucked... but was that due to a single sample with the firmware in use? I think that highlights the very significant role that firmware can play in performance, it's not all hardware. the wifi performance claimed-vs-measured also shows where the engineering department vs the marketing department wrote the sales literature.
