Wait for optimal connection something

The consistently positive reviews can I join, the speed is ok.
A note on the range. I run the card with the Asus RT-AC66U router. The router is in the basement, so arrives the cable provider. Concrete ceiling (diagonally irradiated) wooden ceiling and antenna behind the computer - still excellent field strength. BUT: Not from the beginning and only with the correct setting!
So the first adjust the antenna properly, ie at right angles to each other. This means that the antennas are as if you put a cube on one corner and orient the antennas on the edges. Then on computer and WAIT: The router can with the three antennas radiating align ("Asus AI radar", the phasing of the antennas is well adapted), is supplied so excellent a stationary receiver.
