Sorry about making you feel like a traitor but thank you for the information. If I would have been an expert and would have been able to fix my own problems I wouldn't have needed an active forum but unfortunately I'm far from that. I'm developping a remote control car, actually version 2, and I really need help on differents issues, one of them is actually telnet on the arduino side from the OpenWRT. I might have to shift to the PI and start from scratch... But thank you for your input I really appreciate your honest answers. Hope to see you on the PI side!
