I have response from "intel-driver-man" and I think he is right. I indeed manually enabled powersaving via powertop.
I quote: "This could be caused by power save, which is disable by default in the driver but some programs/distribution seems to enable it without user knowlage. First check: $ iw dev wlan0 get power_save and if PS is enabled, disable by: $ iw dev wlan0 set power_save off and check if problem still happen. @drwt about your remark: > I looked at all kernel versions that had changes committed to iwlwifi and > tested between them. > > I now have determined that I do not have this issue in the kernel version > 4.4.4. > > I do have the issue in 4.4.6 and that is the next kernel version that has > changes to iwlwifi so I guess that is the first bad version." This does not make sense as 3945 device is handled by iwl3495 (iwlegacy) driver, not by iwlwifi. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1627828 Title: iwl3945 crashes randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1627828/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
