Oh, and if you are trying to reach the local speedtest.net speed, but select 4g, it is defaultin= g 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 pus= h it,
change in preferences streams down to 6 and streams up to 2= - 4

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

So that is why the upload g= raph is no good, but the upload number is about right.

Also it did have stalls and drops but not too bad, not enough to trigg= er an error.

Thanks - I'm surprised to see how well 4G handles this.=C2=A0 I was
expecting to see higher delays under load.

The upload graph looks a little strange.
