MK63 Connection to Second Satellite

[NYSpur]

System is set up but the satellite distance from the router and from each other is not what I hoped. I was hoping to have router on top floor and a satellite on first floor and one in basement. I finally found a location on the first floor that worked but efforts in the basement have been inconsistent and limited. Most of the time a blue led would turn to amber. At the moment, I have the 2 satellites showing blue connected, but they are 4 feet apart on the first floor. Spoke at length to customer service and they made some setting changes but no real long term change. 

Any constructive suggestions will be appreciated!
