I am new to Ubuntu and recently lost internet connection - cannot connect to 8.8.8.8 or google.com. I open the network manager and it says I'm connected with the correct hardware address and IP Address fe80::1037:4526:e2b:d5c3 . However, this is not the IP address of my ethernet router. Here are the output of some relevant commands:

$ ip addr

It seems odd that the route output is blank and also that the eth0 device is missing from interfaces. How can I get connected? Thanks!
