I reopened the bug because the change made in network-manager 0.9.0-0ubuntu2 breaks connections using mobile broadband devices (the connections fail silently). Notified the NM mailing list about the issue on the patch from Tore.
* debian/patches/lp761558_default_ip6_setting_auto.patch: default to AUTO for IPv6 method if the setting is missing (e.g. default new connection for new devices). (LP: #761558) This will need more investigation and I'm still looking into it, but mobile broadband connections tend to be useful, so I disabled the patch for the time being. ** Changed in: network-manager (Ubuntu) Status: Fix Released => Triaged -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/761558 Title: Default to enabling IPv6 addresses, but set to optional to bring up devices Status in “network-manager” package in Ubuntu: Triaged Status in “network-manager-applet” package in Ubuntu: Fix Released Bug description: Binary package hint: network-manager Ubuntu 11.04 Beta 2 does not support IPv6 networks out of the box. It really should. (Microsoft Windows have had this support since Vista.) The remaining IPv4 addresses are depleting fast - as of yesterday, there are no more IPv4 addresses to be had in the Asia-Pacific region, a situation which soon will happen in Europe and North America too - likely before the end of the year. It is therefore urgent that IPv6 networks are supported out of the box - average end users cannot be expected to jump through hoops in order to get a working network connection. Fortunately, all the necessary support is found in the NetworkManager source code - it is just a matter of changing the defaults so that both IPv4 and IPv6 networks are supported equally well, as well as hybrid IPv4+IPv6 dual-stack networks. These are the defaults that need to change in the standard connection profile: Require IPv4 addressing for this connection to complete: OFF IPv6 Method: Automatic Require IPv6 addressing for this connection to complete: OFF I've attached a log from when I first activated a connection to a IPv6 wireless network (which failed), and then another attempt after having modified these settings (which succeeded).
