I have today been using flent to do RRUL tests with the values set at 50%.

I have uploaded the first test I have performed. It can be seen at,
http://imgur.com/6DrMJKI.

I'm a bit confused why the DS speed is only 7Mb/s when every other speed
test I have done is around 28Mb/s (as it should be). Can anyone explain why
this might be? Am I doing something wrong?

I would appreciate an expert analysis of the graph, if possible :)
