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.
