Hello,
Buy an ArduinoYun a year ago. This worked as a small meteorological station.
It worked 7 hours a day taking measurements of temperature, humidity and activating a small water pump, all visible from internet.
The problem is that now always returns the following message :
Unable to launch the CGI program Requested :
/ Www / cgi- bin / luci : Input / output Error
It works ATmega32u4 processor, and respond Sketchs by the serial port. The Linino processor is accessible by console (port 22) and the wifi is created, but not light the blue LED WLAN, and LUCI it is not accessible: http://192.168.240.1/cgi-bin/luci/webpanel/homepage.
I have resetted factory but the problem continues.
More information load the YunSerialTerminal example sketch with the Serial Monitor. The Linux boot messages: Arduino Yun don't create wifi network - #4 by ardutober - Arduino Yún - Arduino Forum
I need help.
A lot of Thanks.
