No Network Connection on 10.10!

Are the lights on the network device flashing etc? Is the light on the router on?

Yes, the lights are on, on the router. And nothing is flashing, the lights are steady.

Try a different port on the router, they should flash to my knowledge

I tried that and nothing happens no lights flash. The non working computer is connected via Ethernet and the cord is plugged into the router.

Is there a working PC on the same LAN (to verify the port is bad)

Can you give the output of:

sudo lshw -C network; lsb_release -a

Thanks

You have an IP. If you run:

ping -c 4 8.8.8.8

Do you get replies?

rvam45@rvam45-K7VT2:~$ ping -c 4 8.8.8.8

ok cool, run:

gksudo gedit /etc/resolv.conf

delete all the text and add these 2 lines:

nameserver 8.8.8.8
nameserver 8.8.4.4

Save the new file and try the web, does it work?

Just wanted to let you know I got my PC running again. It was the Ethernet cord, I replaced it and that did the trick. Thanks for all your help.

Thanks actionparsnip, that solved my question.
