@Jean-Baptiste I'm pretty sure this is a duplicate of bug #1426122.
When your network fails, can you grab the output of the command 'nmcli d'? The problem we've seen on arale & krillin with network-manager 0.9.10 is that the patch that makes network-manager ignore devices owned by rild, wasn't updated for arale & krillin, and the NM 0.9.10's behavior changed slightly such that it now will try and manage the rild devices when they become active. ** Changed in: network-manager (Ubuntu) Assignee: (unassigned) => Jean-Baptiste Lallement (jibel) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425987 Title: Cellular data connection stops after a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1425987/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
