Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I was using the AnyConnect client when it froze and I had to do a hard reboot of my computer. Now I can't connect to the internet at all, with or without VPN. The Network Connections manager seems to think I have a wired and wireless connection without a problem, but I can't go online.

I have tried using /etc/init.d/networking restart and it even says it is "ok" with no luck.

I am guessing I need to clear some settings somewhere and restart a service, but I am not sure what. Thanks!

This Cisco stuff changes your /etc/resolv.conf. I have to manually remove the DNS entries it configures every time I have to use it. It just leaves without resetting anything on stop.

Make sure your /etc/resolv.conf just contains one line like this:

nameserver 127.0.0.1
