After the upgrade to 16.04 LTS, internet won't work

Question

I have upgraded to 16.04 LTS (from 15.10). Wi-Fi and LAN both shows connected, but internet is not working.

I have done re-installation of Broadcom wi-fi drivers (through additional drivers), restarted network-manager services. But problem not solved.

When you boot up using liveCD does it work ? – Scott Stensland Apr 23 '16 at 05:36 — Scott Stensland, Apr 23 '16 at 05:36

Sounds like a DNS problem...

Check if you are able to connect to your router IP. (if you can, it probably is)

Check your ifconfig for DNS and Gateway info.

If it is a DNS problem, recheck your network configuration on DHCP and/or use a static lan address with your router/dhcp server as 1st DNS, and other DNS servers following.
