Hi All,

I'm looking for some guidance on the placement of my 2 EAP245s.  Currently I don't have one for floor 1 (basement), but I will look to get one at a later date.  Coverage down there is pretty good, and we don't really use it yet as we just moved in.  I'm currently looking to optimize coverage on the 2nd and 3rd floor. 

I setup the AP on floor 2 (main floor) like this, but as you can see in the picture below its facing the stair case going up, and it's 'back' is to the rest of the main floor - do these things transmit backwards too.  Based on how these things transmit, is it better to place it on the ceiling? 

For the 3rd floor (upstairs) - I can actually place the AP on the ceiling (if I can get through insulation to run a wire) or on the wall in the closet (much easier to install),.  Any suggestions on the best placement?  I have not mounted this one yet, it's on the floor of the primary bedroom.

Below are the floor plans, the blue stars are where there is Ethernet in the wall. 

Thanks!
