I tried to 1. boot with Wifi enabled, then disable it. 2. Boot with Wifi disabled The result is the same, there is a cellular data connection, which drops after several minutes.
The signal is usually 2 or 3 bars, never less, never more. I'll try Sergio's tool. -- 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/1425987 Title: Cellular data connection stops after a while Status in network-manager package in Ubuntu: Incomplete Bug description: current build number: 122 device name: krillin channel: ubuntu-touch/devel-proposed alias: ubuntu-touch/vivid-proposed last update: 2015-02-25 15:06:29 version version: 122 version ubuntu: 20150225 version device: 20150210-95b6a9f version custom: 20150225 Test Case: 1.
