Duet not working

[bonzuccio]

Hi, after first installation, connection and firmware update the receiver has started to blink blue then return to red, blue and blinking blue..
turning off the remote and then on another firmware update was asked, now the receiver is blue...
did I miss some step?
My duet seems broken :(

Now it seems to work.. but it's not simple and the duet update procedure
is scary!!!
Things went fine after connecting the receiver to ethernet cable and not in wireless.. it seems that the update with ethernet succeeded
