This question already has an answer here:

I have seen some questions similar to mine but not the same. I have just gone through the process of installing 12.04 dual boot with WIndows 8. Before I resolved all my boot issues and ran ubuntu I could connect to the internet no problem. Now I can connect to my router and ping is OK, but no applications can reach the internet. pinging google fails.

On a similar user question someone suggested pinging That does work.

I think this went bad for me when a large number of updates were installed.

  • Have you tried rechecking your subnet mask and router settings? – user231466 Jan 3 '14 at 20:34
  • Do you have a nameserver entry in /etc/resolv.conf? – user231465 Jan 3 '14 at 20:39
  • 1 is google. So if you can ping it, "the internet" is working. The problem is likely to be with DNS. See askubuntu.com/questions/130452/… – Panther Jan 3 '14 at 20:55
