i have been messing with the arduino yun for a few weeks now and i was trying to tweek the settings for port forwarding and now the arduino will not connect through ethernet and will not connect through wifi saying that my device fails to obtain an ip adress, is there a way i can COMPLETELY reset all of the settings on my yun and start over?
Yes, as mentioned in the docs http://arduino.cc/en/Guide/ArduinoYun#toc6 you can reset by pressing the WLAN RST button for more than 30 seconds.
Since you are resetting, you may also want to upgrade your yun to the latest version available (see my signature)
thanks but I tried that and now it won't allow anything to connect to it so I can change the settings back, see when you reset it that way all it does is reopen the preset arduino wifi server, from what I have read it doesn't change any of the settings, so what I am looking for here is to completely reset all of the settings and software as so I can start fresh.
This will put your yun back to the default settings entirely:
