Hi cesarf,
If your linux box was working with NeoRouter but it fall in sleep itself, you can use the wake-on-lan button to wake it up from any other box running NeoRouter. Of cause your WOL must be enabled, including both hardware setting and OS settings. Different linux distributions may have various tools to set WOL.
