I have not confirmed this yet but if you can catch the file when the connection is dropped try using wget -c to retreive the remainder of the file. so far the second windows download seems to be working.
Method is as foolows
open up terminal
type cd /path/to/file/directory hit enter
then wget -c http://www.theurltheservergenerates.com/
you can copy and paste the url in mac terminal.
