You should check the following (in order of increasing complexity):
1) Do you have an IP address?
Hint: https://www.cyberciti.biz/faq/linux-ip-command-examples-usage-syntax/
2) Can you ping another host on your network?
Use the ping tool (man ping) to ping the IP address (NOT hostname) of another
machine on your local network, perhaps your router.
3) Can you ping a remote host?
Try:
ping 8.8.8.8
4) Can you ping a remote host by name?
Try:
ping www.google.com
If this doesn't work and the previous did work, you are likely to have a problem
with DNS.
5) Can you download a website (this is a very basic non-HTTPS website that removes
some complexity):
Try:
curl http://info.cern.ch/
