Just picked up a Nighthawk X6 R8000 over the weekend. It is mounted on a wall in the living room on the first floor of our 2 story 3600 sq. ft. house. I have the six antennas flipped out as as far as they go. The top two and bottom two antennas also articulate up or down. There is nothing in the manual about the best positioning for the antennas when wall mounted. Has anyone found an optimal position for them?
