WHITE SHADOW - I YIELD TO GRANDPA
He knows lots of STUFF. I always read and pay attention to his advice.
I do want to say that I was not suggesting that your upload speed was affecting your downloads. It's other people's upload speed and other settings which will affect your downloads. I think your original upload setting was correct for the results of the speed test you provided. Your upload and download speeds may be a wee low but follow Grandpa's tests.
You did indicate that downloading a file showing 10 or more hosts presented another problem. Mind sharing that problem?
