Why am I getting a "network is unreachable" error on Ubuntu Server?
- by jason328
I'm a completely new to Ubuntu server and am having a hard time connecting the server to the internet.
I first ran ping -n 8.8.8.8
connect:Network is unreachable
Then I ran ifconfig

Again there is more but it's giving info on the driver itself. I know it works, I've used it. I assume then that my network got disabled when I installed Ubuntu Server. How do I enable it?
I checked and the internet cable is connected to the D-link router. I have also used this same computer for internet access when I had Ubuntu Desktop installed so internet does work.
