Beware the back panel #WLAP(x1) has been changed to WLPM.  It is now two (2) pieces that need to be screwed together. I wasted numerous hours trying to figure it out thinking I was sent the wrong part(s).
No instruction manual or part number change notification were included in the box and no video instructions can be found on their website. It was only brought to my attention after contacting customer service.  Very frustrating!
