Restarting network-manager.service fixes the issue reliably. I'm going to see if there is more in the log there to determine what is failing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828134 Title: Wifi not working after suspend/resume cycle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1828134/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Andrea -- 1) No D state processes 2) interestingly, `iwlist wlp4s0 scan` shows data like usual 3) rfkill shows everything off I'm going to read up on how to connect to networks from iwconfig and see if that helps me at all. I'm attaching a debug.txt file with a bunch of the output you asked for. ** Attachment added: "debug.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1828134/+attachment/5262781/+files/debug.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828134 Title: Wifi not working after suspend/resume cycle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1828134/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1828134] Re: Wifi not working after suspend/resume cycle
Interesting that the d3cold_allowed change made some differences (I'm assuming it was failing 100% of the times before that change). Few more questions. After a bad resume: 1) are there unkillable processes (D state) in the system (`ps axuw | grep D`)? 2) does `sudo iwlist wlp4s0 scan` return any error or does it hang indefinitely? 3) do you have bluetooth enabled (what's the output of `sudo rfkill list`)? As a temporary workaround you can automate the modprobe trick (#3) doing something like the following: $ cat /lib/systemd/system-sleep/iwlmvm.sh #!/bin/sh case $1 in pre) modprobe -r iwlmvm ;; post) modprobe iwlmvm ;; esac But it'd be nice to find a proper solution to this.

[Bug 1828134] Re: Wifi not working after suspend/resume cycle
Hi Andrea -- Thanks for the suggestion. I attempted this and it seems to not help. The first suspend/resume worked, and I was hopeful, but after 4 more attempts (obviously I have reboots in between each failed attempt), it didn't prove to be a solid option.

Can you try to set the following before suspend: echo 0 > /sys/class/net/wlp4s0/device/d3cold_allowed And then test a suspend/resume cycle. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828134 Title: Wifi not working after suspend/resume cycle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1828134/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also note, the following sequence seems to avoid the problem so far (4/4 in testing, not conclusive, but it's looking good): ``` dpb@aries:~[]$ sudo modprobe -r iwlmvm # Suspend/Resume, then... dpb@aries:~[]$ sudo modprobe iwlmvm ``` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828134 Title: Wifi not working after suspend/resume cycle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1828134/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
