Instructions for starting up the Deepracer:

1. After logging into the deepracer computer, check the internet connection using the command:

$ ping google.com

• If the ping works, you are done!
• If the ping does not work, try to ping Google's public IP addresses directly

$ ping 8.8.8.8

• If this ping works, add Google's public DNS server to the /etc/resolv.conf file on the deepracer computer:

$ sudo nano /etc/resolv.conf

• Add the following line to the resolv.conf file

nameserver 8.8.8.8

• Save the file and exit

$ control-O 
$ Enter 
$ control-X

• Check ping again

$ ping google.com

• If ping still does not work, give up
