If you haven't done so already you may follow these steps here .
1. Open the /etc/default/networking file.
2. Modify the CONFIGURE_INTERFACES parameter to be as follows. Then close the file and save it. (CTRL+X)
# Set to 'no' to skip interfaces configuration on boot CONFIGURE_INTERFACES=no
3. Open /etc/network/interfaces and set the IP information. Then close the file and save it. (CTRL + X)
# interfaces(5) file used by ifup(8) and ifdown(8) # Include files from /etc/network/interfaces.d: # source-directory /etc/network/interfaces.d auto eth0 iface eth0 inet static address 172.16.100.253 netmask 255.255.255.0 gateway 172.16.100.1
5. Be sure to comment out any lines above the new declaration. When done reboot. Your Jetson Nano will start on the static IP Address.
