So I have 12.04 on a HP Pavilion g series laptop.

12.04 works fine on my computer.

Then several weeks ago, my laptop would no longer connect to the internet. My tablet connects fine. I booted ubuntu on my USB and it works fine. Something seems to be wrong "within" Ubuntu.

I have now reinstalled ubuntu 4 times. After varying amounts of time the same problem reoccurs (and I have stopped updating any software in case this is the problem).

I use Cisco Anyconnect and Real VNC to log into a server somewhere else (they are the only programs I could imagine causing any problems).

In Ubuntu 12.04 and later /etc/resolv.conf should be a symbolic link to ../run/resolvconf/resolv.conf. The latter is generated dynamically by the resolvconf utility. Interface configurers are supposed to be resolvconf-aware.

Third-party interface configurers and in particular third-party VPN interface configurers are frequently not resolvconf-aware and write to /etc/resolv.conf directly, and don't restore the symbolic link afterwards. They leave the machine with a misconfigured resolver. Please check for this problem.

If you have this problem then you may be able to fix it by running

dpkg-reconfigure resolvconf
