I see a similar effect on mako vivid-proposed. Sometimes after doing nothing for a few hours I pick up the phone and find it having no data connection at all, without any action from me. This could potentially be because of short 3G network outages. I can confirm that switching from 3G to 2G in the indicator triggers that.
BTW, I tried to enable/disable flight mode, disable/enable mobile data, and further toggle between 2G and 3G, and nothing of that brings it back. Although I didn't wait for a very long time, I'll give it 30 mins now. -- 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/1418077 Title: NM fails to create a cellular data connection for a unacceptably long time Status in the base for Ubuntu mobile products: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: Steps to reproduce: 1.
