Ubuntu – Cannot connect to the internet after installing Cisco AnyConnect VPN Client

cisconetworkingvpn

Today, I tried to install the Cisco AnyConnect VPN Client on my computer running Ubuntu 12.04 updatet earlier today. I followed the instructions on this webpage https://innsida.ntnu.no/wiki/-/wiki/English/Install+VPN, but after I had typed in my username and password, it failed to connect and my computer was no longer able to connect to the internet.

It finds my router with no problems and it pings my DNS server as normal, but it times out when I try to ping www.google.com for example.

I realize that more information is probably necessary for anyone to help me, but I don't know much about networking.

best regards

Cisco AnyConnect VPN Client makes changes to /etc/resolv.conf. Make sure that the program restored /etc/resolv.conf to its original state. /etc/resolv.conf should be a symbolic link to "../run/resolvconf/resolv.conf". If this is not the case then run

sudo dpkg-reconfigure resolvconf
