No internet connection after Ubuntu 12.04 upgrade? Here is what I did to solve the problem. After I upgraded from Ubuntu 11.10 to ubuntu 12.04 I had no internet connection not wired or wireless. Here is the symptoms and how I solved them:
After the Ubuntu 12.04 upgrade I noticed that XBMC was missing, while this may be unrelated I wanted to reinstall it using apt-get install xbmc xbmc-standalone in the terminal. This echoed the following message
Something wicked happened resolving ‘dk.archive.ubuntu.com:http’ (-5 – No address associated with hostname)
So I googled around and found that the problem lies with the wvdial package, which is uninstalled during the upgrade. So to solve the problem I simply had to reinstall that package. As I could not access the internet wired to a router or connected wireless – I had to use my 3g dongle. This turned out not to be a problem, so to solve the problem:
In the terminal write
sudo apt-get install wvdial
After the installation I tried to connect to the internet through a wired and a wireless connection, and had no problem.
If you are not as lucky as me to have a 3g dongle, simply download the package to a USB from here http://
dpkg -i wvdial_
Update: If this is not working, you might want to try to add a DNS server. Thanks to Alan for point this out.
