Please kindly help with placement of RBK50

I need to clarify my orifginal post.  Sorry.

What I really meant to say is that I can only place the main modem with router on either floor #3 or floor #1, as that's where the coaxial cable cable is.

I can place the satelite on any floor, as it doesn't require the coaxial.

So, the four options I have are:

1. Router on floor 1, satelite on floor 2

2. Router on floor one, satelite on floor 3

3. Router on floor 3, satelite on floor 1

4. Router on floor 3, satelite on floor 2

Which is the best option?
