I forgot to mention what works and what don't on the image I used, even though, I upgraded using the "apt-get" commands.
1. "reboot" does not work. It hangs, and a power off is required to restart.
2. Ethernet does not work, and "MAC address" changes on each reboot.
3. "Wi-Fi" is really bad, I need to place box close to the Router ( AP ). Something no more then 5m ( Chip is 8188 ).
