I suspect one more thing. This code work fine with my mini-pro and my UNO R3, but I got issue with my mega2560.
I can send data from the mega to the router ( tested on asus wl520gs, linksys wrt54gs ) but I cant receive any data from the router to the arduino.
Level ttl issue ? 5v on one side ( arduino), and 3.3 from the router ? Soon I got time I will put some level shifter between arduino and the router, and test again.
i have arduino UNO R3 too,
you mean if one side 3.3V and other one 5V i will have issues ?
cisco e900 used only 3.3V
