Hi, Just to let you know I'm running Feisty (herd 5) on a Dell D610. Using a wired network I get similar problems (the network often fails to get a IP address from DHCP after resume if the lease has expired).
Restarting the computer causes it to successfully get a IP address. Also, it is not a problem with kernel modules. When NetworkManager fails to get an address, I can disable it, go to command line and $ sudo su $dhclient3 eth0 and my computer will be on the network no worries. Let me know if you want more info about my system. -- NetworkManager can't find interface on resume from suspend https://launchpad.net/bugs/45696 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
