What is the model# of the SB modem? Just making sure it's a stand alone modem and no built in router. 

You can try the following:

Disable Beamforming, MIMO, Daisy Chain and Fast Roaming if these options are seen on the router. Under Advanced/Advanced Settings/Wireless

Try setting manual channel 1, 6 or 11 on 2.4Ghz. Any unused channel on 5Ghz. 

Set WPA2 and AES only. 

How big is your house? Sq ft.

Modem SBG65880. Yes it was combo modem router. House size 2500sf. As for your suggestions , I will not be able to do. Just thought there would be a simple answer as to why the light on the downstairs unit is off and the one upstairs is on. Thanks for trying anyway

It's recommeded to turn the modem/router in to a modem mode only if it's currently running as a router. And disable it's wifi.

This can cuase problems with the Orbi.

 What firmware is currently loaded on both units? 

I would try a factory reset on the Satellite and re-attach it and see if the BLUE led turn off after a while. It should not remain on.

You can try using the Orbi router by itself since you have a smaller size building as well. The Satellite may not be needed.
