I have wireless Internet access and it worked well on Ubuntu 12.04 LTS until today, when I installed updates from the Update Manager. After the reloading of the computer the sign of Internet disappeared and the Internet connection stopped working.

I went to the Network section of the System settings and got such a message:

The system network services are not compatible with this version.

ping 8.8.8.8 gives the result Network is unreachable.

What should I do?

In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
