drwt, the next step is to fully commit bisect from kernel 3.19 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions is not fully commit bisecting. Also, the kernel release names are irrelevant for the purposes of bisecting. It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed. Thank you for your help. ** Tags added: needs-bisect ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1629603 Title: Wifi stops working sporadically Status in linux package in Ubuntu: Incomplete Bug description: Since 16.04 I have been having trouble with WIFI stopping working daily and requiring a reboot to fix. This happens at worst multiple times a day and I dont know what could trigger it, the connection just stops working with no apparent reason and I cant get it back without a reboot. I did not have this problem with 15.10. My access point is ASUS RT-N12E_B1. I did not experience this issue when I was using a different access point for a few days so I'm not sure whether the cause is something specific to this wifi environment.
