Sync Orbi RBS50Y outdoor satellite to new Orbi

This doesn't have enough upvotes. Thank you for the clear step-by-step. After countless hours, this was the fix that worked for me.

A couple things I'll add:

1. To update firware, you'll need to download the firmware from netgear before connecting to the NETGEAR_EXT local wifi. Search for "RBS50Y latest firware extender mode".
2. In the Smart Setup wizard there are 3 password options for both 2GHz and 5GHz:  create new, copy router, or leave unsecured. During the first connection, select Leave Unsecured. You can change this after it's connected to the router. 

Cheers!
