Disabling /etc/rc.local and editing it (Disable it by removing the eXecute bits). I noticed that the default IP of the wifi net was 192.168.1.1, which conflicted with my router's IP, which seems to be what caused the *plug to be apparently unreachable, and networking on the plug to fail.

Thanks a lot! I have been able to start the desktop, using xfce4, but there seems to be a problem with dpi settings or desktop resolution or something... The mouse cursor is OK, but both fonts and windows are extra-large (see the attached image). Any ideas how to fix this? The screen is MIMO UM-740. There is nothing about pixels or display size in the xorg.conf. Also when trying to run Xorg -configure I get Segmentation fault...
