Orbi RBK853 router web interface setup

[lenwhyte]

I plan on setting up my new RBK853 using the router web interface from my Desktop computer.  Do I need, or is it preferable, to power up the two satellites  when I initially power up the Router and commence the setup?

No. you can set them up/sync them later if you prefer. 

I've done it both ways where I add the satellites right away and added them later when I wanted more/different coverage
