Getting root access to the Fonera

There are many ways to gain access to a router hardware. Some vendors provide a way to flash the router through an upload interface. Other vendors (like ASUS) provide a TFTP flash procedure. Most devices however somewhere have serial pins with which you can directly access a root shell. That's the case with the fonera router.

Nevertheless, you can't just connect it to the serial port of your workstation, because the voltage levels are different. You need to adapt the 5 V, or even 12 V from your computer to the 3.3 V on the device and vice versa. The 3.3V level is called TTL. For this reason I have built a level shifter, but you can buy ready kits from a multitude of vendors, also on Ebay.

But be careful you get the right converter chip! There are different versions, one for 5 V, one for 3.3 V. You definitely need the 3.3 V version.
