I have an Asus RT-AC87U that I recently acquired. I sold my 68U and only had to pay $10 difference. Anyway, I relocated the router in my office and recently have noticed some issues/interference with my bluetooth keyboard, trackpad and mouse. I have never really had any issues before with my Macbook Pro Retina so I found this to be troubling and interesting at the same time. Looking at the RSSI values when the router is on they are very high 70+ and when the router is off they drop to -58....
