I have just bought an AR.Drone 2.0 (I was in Las Vegas coming back to Brazil, last 06-16-2012). It worked fine since first time I´ve turned it on, updated its software and started to command it. I have played with it during all last week and everything was fine. But last friday night, when I turned it on again, it went green as usual, turned on its wifi communication, connected with my iPad and started to update a new software version. After done, I turned off my wifi connection on the iPad and turned it on again. At this moment, my iPad didn’t find the AR.Drone WiFi connection! The lights of the Drone were turned off. I tried turn off and on again my iPad connection, without success! Then I disconnected the AR.Drone battery and connected it again. It went red and after a while, turned off without turning green! And it is like this since then! The battery is ok and full of charge. I tried to repeat the procedures without success! The AR Drone doesn´t go green, neither turns its wifi on! The software on my iPad is Version V2.0.21. But without wifi connection I can do nothing! Can anybody help me with this issue ? Tks in advance.
