WWAN interface changes name and stops working after suspend #22533

Open mikael-andersson opened 7 years ago

mikael-andersson commented 7 years ago

Issue description

WWAN interface changes name and stops working after suspend, but usually starts working after another suspend. The problem reappears after some suspends but under which circumstances I have not identified.

First I will show log excerpt from when interface works and further down when it works.

After a suspend, but not every one, the WWAN interface changes name and stops working:

mikael@nixos> nmcli dev DEVICE TYPE STATE CONNECTION ttyACM1 gsm disconnected --
wlp3s0 wifi disconnected --
lo loopback unmanaged --

Below excerpt from the log when I cannot connect with my WWAN:

After most suspends, the WWAN interface gets the right name and works (I might however need to restart the ModemManager to get it to work, but I regard that as a separate and minor problem):

I just realized that I should have written down exactly what error message I get when trying to connect when the device name is such that I cannot connect. I will try to complement with that information as soon as I get the problem again.

Steps to reproduce

I have not been able to determine what to do to reproduce more than suspend a number of times until the problem reappears.

I have the same problem on Arch linux. Did you find any solutions?

cyrinux commented 6 years ago

Same problem too on archlinux

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

  1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
  2. Ask on the NixOS Discourse.
  3. Ask on the #nixos channel on irc.freenode.net.
