Thank you for your answer rjonsen. Unfortunately I was expecting results from a source ranging from 80 MB/s to infinity and beyond. To describe the question completely : At a distance of 2-3m from the router, in 802.11ac, some reviewers measured around 600Mb/s while others measured only around 300Mb/s. So what's the value you owners get from it with a recent firmware...?
Unfortunately I live in a small village with copper wire connection, max. 5000, in Practice only 3500 ! So thecFritz box does not have to run at anything close to its top speed . . . For me I get the max. of 3500 within 10 metres of the box ! Hope this helps . . Btw, I am very satisfied with the box!
