What FW version is the system currently using?
Same version on both?
Whats the distance between the router and satellite? 30feet should be starting distance.
After the top LED starts to pulsate on and off slowly, press the sync button on the router then on the satellite. Wait about 2-3 minutes and top LED on the satellite should turn on BLUE.
