I used to connect to my ar-drone 2 using my laptop with telnet, ftp, ffmpeg and node - but out of the blue they all fail now. I'm still able to connect to the drone using my phone (both through ar-freeflight and through telnet).
When connecting to my laptop I'm able to obtain ip, and I can see on wireshark that the drone keep sending udp packets to me on port 14550 (if it helps identifay the problem).
I did factory reset (pressing a pin under the battery), and made sure I have latest version. I also read that thread- but didn't understand what was the solution
