In order for the Atlas 200 DK to access the Internet to perform apt-get update, it is connected to the host via USB cable, and to the router via Ethernet cable.
In the developer board itself, the eth0 should be changed to dhcp connection.
After running the service networking restart command, you can try to ping any website.
This means the developer board is success to access the internet.
However, IP port conflict might happen for some router, it will not be able to access the internet and this might occur.
This problem can be checked by running ifconfig in the board itself. Both the eth0 (192.168.1.21) and usb0 (192.168.1.2) have the same network port hence causing the conflict.
The IP address of the eth0 is assigned by the router automatically, so for this we could only change the IP address of usb0 of the 200 DK. Try change the IP address to a different network port, for example 192.168.3.2 and reboot the board itself, take note that the future ssh login into the board will follow the IP address that you have changed to.
