Orbi satellites do not connect anymore

[SnorkyMN]

Yes, but where to set the channels for the connection to the Satellite?

[FURRYe38]

On the RBRs web page you can change channels there. Basic Tab/Wireless. 

There are not channels to change for the RBS. What ever you set on the RBR the RBS will follow. 
Only channesl to change are the 2.4Ghz and the 1 5Ghz radio. The wireless backhaul can't be changed as thats handled automatically. This is not user configurable.
