For me:
work-wire OK
work-wifi OK
home-wifi FAIL
I don't use a wire at home so I didn't try

Then I do sudo service network-manager restart and I can surf again. In
that time while I can't sufr the internet I get ping 8.8.8.8 and other
IP's. Torrent dowloading is also working in that time. So, this is
obviously a dns and network-manager issue.
