I've removed everything, but the 'lo' interface in this file. It
didn't help me. As soon as I set the manual configuration in the
network manager and set the dhcp on the wired network and enable it,
the network manager adds the entries about this interface to
/etc/network/interfaces itself. If I don't set it manually, it also
does nothing.

And again, after I manually set the dhcp connection it connects
somewhere, and I see address 0.0.0.0. I tried to restart the server.
Here is what the dhcp client told me (after restart):

sudo /etc/init.d/networking restart

So, I still can't get access to the internet :( I don't understand why
on the WinXP it is so quick and easy with the same wire, the same
router, the same all? What is the difference? Maybe the router is
designed to work with Windows or something... Could you please give me
any idea how to setup the internet?
