The clever wife won an Xbox One a while back (july 2014), but recently, the controllers are refusing to stay connected to it, they drop in and out at random.  Also noticed the Kinnect sensor LED seemed to be going on and off at random as well. 

Changed batteries, tried updates, and in the end factory reset the Xbox - this seemed to stop the Kinnect dropping but the controllers still drop in and out. 

Have just connected the controllers via the Windows Wireless dongle on my PC, and theyre behaving themselves, leaving me reasonably convinced it is the Xbox itself at fault.

Now, because it was a prize, and not purchased, do I have a leg to stand on in regards to the CGA ? Or should I be prepared to kiss it goodbye ? :)
