I just noticed that I only looked on the speed for receiving (~8 Mbit/s). I 
did the test again for sending and got 700 - 800 kbit/s. The numbers also 
appear different after I did a test with Linux for comparison, it showed up to 
90 Mbit/s receiving.

I don't know if it has a relevant meaning, but I also get a lot of messages 
"dev_error: Current Rate is not valid"

Cheers
