esteblish a mobile data connection automatically. This feature is highly dependent on the SIM card  
features and the available networks.  
This Option is only availble if the router is equipped with a cellular module.  
5.1.3. Recovery  
Following actions might be taken in case the router has been misconfigured and cannot be reached  
anymore:  
1. Factory Reset: You can initiate a reset back to factory settings via the Web Manager, by running  
the command factory-reset  
or by pressing the reset button. The latter would require a slim  
needle or paper clip which must be inserted into the holeto the right of the SIM 4 slot. The button  
must be hold pressed for up to 5 seconds until all LEDs flash up.  
2. Serial Console Login: It is also possible to log into the system via the serial port. This requires  
a terminal emulator (such as PuTTY or HyperTerminal) and an RS232 connection (115200 8N1)  
attached to the serial port of your local computer. You will also see the kernel messages at  
bootup there.  
3. Recovery Image: In severe cases we can provide a recovery image on demand which can be  
loaded into RAM via TFTP and executed. It offers a minimal system image for running a software  
update or doing other modifications. You will be provided with two files, recovery-image and  
recovery-dtb, which must be placed in the root directory of a TFTP server (connected via LAN1  
and address 192.168.1.254). The recovery image can be launched from the bootloader using a  
serial connection. You will have to stop the boot process by pressing s and enter the bootloader.  
You can then issue run recovery to load the image and start the system which can be accessed  
via HTTP/SSH/Telnet and its IP address 192.168.1.1 afterwards. This procedure can be also  
initiated by holding the factory reset button longer than 15 seconds.
