Netgear Orbi Satellite RBS20 Setup and Reset
Resetting the satellite can clear the 'Orbi Not Detecting Satellite' issue.

It should be really easy to setup your Netgear Orbi Satellite RBS20! First, plug in the satellite and place it close to the router. Next, wait till the white LED starts blinking. Press the Sync button on both the satellite and router to pair the satellite to the router. When the LED glows steady blue, it indicates the connection has been established.
Resetting the satellite can clear the 'Orbi Not Detecting Satellite' issue. Locate the reset, press and hold it for ten seconds, and release it as soon as the indicator LED starts blinking amber. After this, proceed with the installation again.
Set it within range for your reference and ensure firmware updates are applied. Seamless coverage- when enabled- is what Orbi will have!
