I just tried with the live CD where I had the same problem.

Furthermore I got the right DNS which is 195.186.1.111 and  
195.186.4.111. And yes, I'm using a wireless DSL router (Motorola).  
What could be the configuration problem with the DSL router? I never  
change anything there and used it without any difficulties previously  
on Ubuntu. But in the same time it somehow seams obvious that it has  
to be linked to that since at my brother's place (with another service  
provider) everything worked fine.
