I installed a couple of these in a concrete stairwell and am very surprised they can reach floor to floor considering the floors are 12 inches thick. Pretty easy to install with 2 or 3 screws and the included bracket. I don't use them for heavy internet activity, just casual security camera streaming, and they work really well for me.
