Sometimes, in some positions, it stops receiving anything even though the distance to the AP is only ~3 meters and there are no obstacles. Moving it a few centimeters fixes it. Switch the initial gain to maximum coverage when there is beacon loss. This only helps sometimes. This is similar to what the official driver does.
