[Desktop-packages] [Bug 1425987] Re: Cellular data connection stops after a while
So it looks you indeed have hit #1418077. This is pretty obvious by looking in the attached nmlog file, and search for connection '/208150102671184/context1'. You'll see it get disabled at 18:41:24 after a bunch of failed attempts ( modem-no-carrier ). It gets successfully auto-activated again in +5m. That said, I also see something else that concerns me. If you look at the netlog, after '/208150102671184/context1' is disabled, you'll see NM try a 'context3', 'context5', and 'context1' again. The odd thing is that the related IMSI is not '208150102671184' it's '208103698221268'. Looking at network-test-session.log ( also attached ), you'll see that '208150102671184' is the IMSI for ril_0, and that ril_1 is PIN-locked. It appears to me that NM may be trying contexts from other SIM directories it finds in /var/lib/ofono/. -- 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.

[Desktop-packages] [Bug 1425987] Re: Cellular data connection stops after a while
OK, I'll take a dive into the network-test-session logs later today. From your description in comment #9, it sounds like this is the same issue as bug #1418077, where something causes the mobile data connection to drop and NM takes ~5m to restore the connection. If the logs concur with my theory, I will dup this bug and update the other bug to include the scenario where the connection drops on its own ( ie. not triggered by a radio technology change ). -- 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.

[Desktop-packages] [Bug 1425987] Re: Cellular data connection stops after a while
@Jean-Baptiste Can you reproduce this reliably? Also, it sounds like your steps are: 1. Boot the phone w/WiFi enabled, and in range of a remembered access point 2. Disable WiFi 3. Verify the mobile data connection comes up 4. After several minutes, the data connection will drop; sometimes it's re-established, sometimes not. How is your cell reception? Do you a see strong cellular signal on the top-panel? Finally, one thing that might help diagnose would be to install and run Sergio's network-test-session tool: https://github.com/sergiusens/network-test-session -- 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.

[Desktop-packages] [Bug 1425987] Re: Cellular data connection stops after a while
@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 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.
