Might wanna try chaging the download region to something like Greenland/Iceland, thats the one i use : P
I find the Aus servers just cant handle themselves alot of the time when it comes to updates
Ive gone from 4-5kbs down to like 200+ with Greenland/Iceland, though i'm sure any region that is currently sleeping or not as popular would have good speeds too
Also try pause it and unpause to get it off suspended.
