We have Spectrum internet so I ordered it thru them.
I'm sure there are others off the shelf, but just wanted everything to work together
some toys don't play well with others...lol

Easy, just plugged it into a hall wall socket half way,
the green light went blinky, blinky and that was it.
We have a long linear single level house.
I ordered 2 just in case, but didn't need the second and returned it.
Went from 0-1 bars to a full 5.
