Hi Maurizio,

When I switched from cable modem to ADSL, I had to manually lower the MTU size 
in my LInux boxes.  I had similar, though not identical, symptoms to yours, 
where some apps worked fine and others failed. It doesn't (as far as I know) 
hurt anything to experiment with lowering MTU size. If this doesn't work, 
just take the line back out.

sudo kate /etc/network/interfaces     #or use vi, or your favorite text 
editor.
Find the line that starts "iface eth0 inet".  Add this line immediately after 
it:
mtu 1400
Save the file, and exit the editor.
sudo ifdown eth0
sudo ifup eth0

Now see if that helped.

Good luck!
Keith
