As suggested, moving to network-manager. There's no clear evidence of resolvconf doing anything wrong here.

After booting, neither of them could connect to the web. A workaround was to remove the eth0 section from /etc/network/interfaces (which the preseed added). This is the interfaces file before: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp After restarting network-manager service it worked again immediately. It was also suggested that the state of resolv.conf on the system might be a problem: nameserver 209.6.3.210 nameserver 127.0.0.1 search lexenab Removing nameserver 127.0.0.1 and restarting networking/resolvconf and network-manager seemed to fix it. (having looked at the resolv.conf file after it worked again the 127.0.0.1 is back, which is interesting) ProblemType: Bug DistroRelease: Ubuntu 12.10 Package: network-manager 0.9.4.0+git201206081144.2efeac8-0ubuntu1 ProcVersionSignature: Ubuntu 3.5.0-4.4-generic 3.5.0-rc6 Uname: Linux 3.5.0-4-generic x86_64 ApportVersion: 2.3-0ubuntu4 Architecture: amd64 Date: Wed Jul 11 11:41:31 2012 InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Alpha amd64 (20120711.1) ProcEnviron: TERM=xterm PATH=(custom, no user) LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: network-manager UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1023486/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
