Regarding
http://www.dslreports.com/speedtest/380810

The upload graph was broken, or partially so, because you're using
Firefox/24.0 which dates from 2014 and apparently doesn't know how to
feedback information on the upload so the measurement was done from each
upload as it finished

So that is why the upload graph is no good, but the upload number is about
right.

Also it did have stalls and drops but not too bad, not enough to trigger an
error.
  46.98s 10hz drop stats frames=15 total ms=3985

Oh, and if you are trying to reach the local speedtest.net speed, but
select 4g, it is defaulting to 3 streams, and then only 1 up because of the
old Firefox version,
and is using servers in Netherlands and Germany.

So if you try a current version of Firefox and/or Chrome, and want to push
it,
change in preferences streams down to 6 and streams up to 2 - 4
