Good day!
I apologize in advance if this question has already been featured here.
The question is quite touchy and needs a qualitative response.
I understand that Mikrotik is used mainly in the more industrial purposes. However, many of my friends have a problem along the following lines: a laptop connected to Wi fi (n-standard distance of ~ 5-10 m) to RouterBOARD 951G-2HnD. Server connection speed tester connected to the same 951 1 Gbit / s. Test your connection speed always gives different readings from 0 up to 65 Mbit / s.
Indicators in the Asus (price ~80$) router - from 80 to 90 Mbit / s. No less!!!

In this regard, at industrial scale, many opt for the "UniFi".

I confirm that the Wi fi connection "Mikrotik Mikrotik", the channel is not observed huge deflection of the link.

The relevant question: how representative Mikrotik or RouterBOARD can comment on these issues?
