I believe that this has caused a very weird bug in my computer, where NM
was telling me that I was connected to the net, but then it was not
really working: the browser couldn't open pages, evo couldn't fetch my
mails... please, find the details and how I solved it in this thread in
Ubuntuforums:

It's two pages long, but it's enough if you read the first and last
posts. Also, if you have further questions I'll try to answer them.

I could also file a bug if I'm required too, but I'm not sure where the
right place would be.
