Serial monitor not working

[pegasus44]

My Digix was working fine for 2 weeks and now it doesn't print anything anymore on the serial monitor, even if I run the example programs...
I'm running Xubuntu Linux and I haven't installed any new drivers in the meantime and I'm running the "Arduino 1.5.7" as sudo... I cant continue my work because of it and its frustrating.... Anyone have any ideas...

Btw, If I run the basic example blink for example, the lights blink and everything works fine, except for the serial print out...

Can you confirm the Rx/Tx pins still work as Input and Output?

How can I do that?

I found another problem now after I did a restart on the wifi module... When I specify which SSID to pick and put in the password and restart it the password changes to 12345678 for some reason.... I cant connect digix to my network now.... wat.

Why you are running the IDE as sudo?  Just add your user to the dialout group.

Are you using DUE or DigiX code?  Compiling for the DUE you have to use SerialUSB, while the DigiX Code uses Serial

Useless, as the Digix uses virtual Serial over USB.  The USB connection seems to work, otherwise he could not upload new sketches!

Like I said... now I cant even connect it to the network because the password is constantly changing back to 12345678... wth

check if pin 45 of the Wifi card is connected to GND by any reasons!  That triggers factory default reload!
Pin 45 ist the 4th pin from the edge close to the USB connector.

That would make sense, but its not....

Also... all the other setting are updated normally... except the password...
Please help

I restarted the router a couple of times and now the password doesnt reset... I guess it wasn't digix's fault.
I still don't get any serial output on linux, only in windows...
