the result of the command was

No DHCPOFFERS received
No working leases in persistent database - sleeping.
(the configuration of /etc/network/interfaces file was:

mapping hotplug
	script grep
	map eth0

iface eth0 inet dhcp)

I then tried (after I had disabled dhcp server) with

sudo ifconfig eth0
sudo route add default gw

and putting the provider nameserver IP in resolv.conf, modifying 
accordingly the  file interfaces

iface eth0 inet static

but without any result. I'd like to try changing the kernel loaded 
modules, but without my
ethernet card and then internet connection it's almost impossible.

If it's a useful information, ping command runs properly with localhost 
while is not running (host unreachable) with the router's IP (

It's really a pity, kubuntu works very well also in my old desktop, 
keeping out lan connection ...

Any other ideas?
