Each satelitte connects to the router, the sats don't connect to each other (like they would in a mesh network), so what you need to do is try to place the router in a central place.
For example, this would not work well:
R ----- S ---- S
You need to do this:
S ----- R ---- S
Hope this helps. Look at the pictures on page 11 and 12 to see what I'm talking about:
