Help, my arduino yun don not work!

Today I had to use my Arduino yun, but it did not work, I have included it, connected to it, not only that she was doing it for a long time, it is connected through the time when I did finally hooked up, the password "Arduino" did not come, I read so that the same password can be "doghunter", I reset wi-fi setting, it does not work, then I reset all the Arduino with Linux, it did not help, I do not know what to do.
