Before venting let me explain that I am an electrical engineer with nearly twenty years experience using various flavors of Linux/UNIX and even longer programming microcontrollers. That being said this Yun is easily the biggest turd I have ever had to deal with. Windows ME was more reliable than this.
The network connections are sporadic at best and right now I have no idea what the wireless is using for an IP address. The documentation is useless as it apparently does not apply with this device. For example the directions for resetting the WLAN says:
"The reset button for WiFi is located next to the USB-A connector. When you press the button, the WLAN LED will flash."
I have performed this operation over a dozen times and this LED has never lit while pressing this button. It has lit up a couple of times without the button so it does function just not when it is supposed to. I have to repeat this procedure several times to even have a chance of it resetting to defaults. This is only one of several problems I have been having and have just about reached the end of my patience.
After going around in circles the last couple of days even after updating the Linux image I can only assume that this device is possessed by demons and my $75 was an expensive lesson in how to waste money.
