...news... Today to overcome the problem i tried to remove the cable when i lost my connection. It doesn't work because nm-applet continued the network- retrieve. So i tried this command:
sudo ifdown eth0 i received this message: [EMAIL PROTECTED]:~/Desktop$ sudo ifdown eth0 Password: There is already a pid file /var/run/dhclient.eth0.pid with pid 5798864 Internet Systems Consortium DHCP Client V3.0.4 Copyright 2004-2006 Internet Systems Consortium.

So i killed nm-applet and re-connected the cable. It woked because using sudo dhclient eth0 i had a new ip-address. After that i tried to restart nm-applet but it didn't work -- network-manager blocks my keyboard https://launchpad.net/bugs/68364 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
