First of all, I'm a complete novice on Linux/Ubuntu and Plugcomputers...
I got my DreamPlug, put it in... there was a WIFI connection, so I could connect via SSH to the dreamplug.
I found this Quickstart on the Wiki. http://www.plugcomputer.org/plugwiki/index.php/QuickStart
Following instruction step 2 and 3, reboot and the WIFI connection was lost.
I got a JTAG, so I can connect to dreamplug, but how to reset the system?
