I change the depth and no. of external links a bit. It seems to work much more
as I can have the whole download time extended to almost 1 hour (initially 20
minutes only).

But then when I think it is enough, I click cancel. It flashes an instruction
that "Finishing pending transfers - Select [Cancel] to stop now..."...Do I
really need to click once more the cancel button as I saw there seems no
internet flow in my lan card lights?
