Hi @Slickslr, The speeds you're getting are typical and actually quite normal for a NBN 12 connection, if you consider that 1 Mbps = 0.125 MB/s let's say you were downloading whilst connected at the typical evening speed of 11.1 Mbps you would have a maximum rate of 1.3875 MB/s.
Once you factor in variables of WiFi connections you're pretty much right in the ball park. Also remember that all the users on your network need to share that available bandwidth so if someone is downloading lots of data it will noticeably affect the other users.
44.5 Mbps will give you a download rate of 5.5625 MB/s, It should take between 7-8 hrs to download 36gb on your NBN 12
Don’t confuse Mbps with MB/s they are different animals, as I said 1Mbps = 0.125 MB/s
