I have the same problem with a fully updated Ubuntu Feisty on a Desktop (DELL Dimension 4700). I'm trying to use Hibernate or Suspend as they save energy (compared to leaving the computer on) and time (compared to a full shut-down/restart). Not being able to use the network half the time after Resume from Hibernate/Suspend is a serious usability issue for me.
I'm sorry to say that I'd never had this problem with Windows XP Pro or XP Media Center Edition. I also don't remember this problem with Ubuntu Edgy. The network was just re-detected immediately. Feisty risks being perceived as not environmentally-friendly if it cannot handle Hibernate/Suspend properly. With Feisty, it sometimes helps to use System > Administration > Network > Configure, and change the Wired Connection > Properties from DHCP to Local Zeroconf, and then back to DHCP again. But other times, it does not help. I have the following WIRED Ethernet card: Intel Corporation, Device: 82562ET/EZ/GT/GZ - PRO/100 VE (LOM). Network device: eth0 Hardware address: 00:13:20:0e:ce:fb. I use DHCP networking via my wired router. Background: Suspend or Hibernate only work when I use the open-source ati video driver, not the closed-source one that the Update Manager recommended after upgrading to Feisty. I'm not sure if it's related, but I'm mentioning this just in case. Thanks in advance for your prompt attention to this matter. -- NetworkManager can't find interface on resume from suspend https://bugs.launchpad.net/bugs/45696 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
