Got my R2 today. Happy with it till now.
Initial setup didn't go smoothly. Initially it was saying "No internet connection detected" when connected to my modem (netgear CM500).
So, had to setup without internet connection. Then factory reseted the device and then first restarted the modem with r2 off but the lan connected. Once the modem came online, then turned on the r2 and setup again from start. This time, it detected internet connection.
Cheers!!
