Orbi - Wireless Network not available or LED flashing white on Router or Satellite

The RBK50 router and satellite are auto-updated to fw  V1.12.0.18 with all parameters at default settings and connect to a BT smarthub box. Speed has improved but sadly video streaming on all iOS device  (all six ipads and iphones in my family) constantly dropped every few minutes. Thought it was signal strength and purchased RBW30 as 2nd satellite. I spend 2 hours trying to install it and the thing just kept flashing white and pulsed to solid blue and never shown the solid white stage. Try numerous methods (app, web, hardware reset) according to instructions and forum's advise - could never connect this second satellite.

Never have so much trouble in installing a router/wifi device. With dropping wifi on iOS device and so much troubles in adding 2nd satellite I simply decided to return the whole thing yesterday. Voting on my feet is the best feedback I can offer to a technically advanced hardware but wrap under a totally unacceptable and poorly implemented software. Perhaps it will get better in 6 months after all us guinea-pig customers have finished the public beta tests for the company.
