Public bug reported: Summary: If I suspend-to-ram while connected via the wired ethernet card (eth0), and then resume with the ethernet cord unplugged but in range of a wireless access point, network manager will correctly establish a connection with my wireless access point. However, /etc/resolv.conf still reflects the wired ethernet connection, so the wireless internet connection doesn't work. The problem is easily fixed by running the command 'sudo resolvconf -d eth0'.
Steps to reproduce error: 1) Have laptop connected via wired network connection (eth0). 2) suspend-to-ram 3) unplug ethernet cord 4) move to within range of wireless access point 5) resume computer What happens: Upon resuming from suspend-to-ram, network manager will detect my wireless access point and establish a connection. However, /etc/resolv.conf still shows the name servers that belonged to the wired ethernet connection. This means that the wireless network connection gives the impression of not being connected. What should happen: network manager should inform resolvconf that the wired network connection has been taken down, so that resolvconf removes the corresponding entries from /etc/resolv.conf. Temporary work-around: upon resuming, run the command: sudo resolvconf -d eth0 This removes the entries from the wireless network connection from /etc/resolv.conf, and replaces them with the entries belonging to the wireless network connection. Oddly enough, the problem doesn't seem to happen in reverse (switching from wireless to wired). I'm running Edgy Eft with network-manager-0.6.3-2ubuntu6. While I am at work I connect the laptop via the wired ethernet card (eth0), but while I'm at home I connect using a wireless network card (ath0). ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- network-manager not deleting resolvconf information on resume from suspend https://launchpad.net/bugs/84313 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
