    Computer Periodically Crashes (Usually within a Day)

    Did a fresh install of Ubuntu 18.04 LTS, but my computer now periodically crashes. Seems to have to do with my WiFi? It's integrated with my motherboard (https://www.asrock.com/mb/Intel/Z370%20Taichi/)

    Never had this issue on 16.04 LTS. Below is what I see in /var/log/kern.log

    Code:

    Any help on how to resolve this would be much appreciated!

    Moved to Networking & Wireless sub-forum
    See sticky on notes before posting. It wants you to run a script to have details on versions and configuration, so those that know wireless issues can make suggestions.

    Re: Computer Periodically Crashes (Usually within a Day)

    I've disabled power management in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

    Will report back if that helps

    Re: Computer Periodically Crashes (Usually within a Day)

    Are you using any Asmedia ports for drives?
    That almost always causes issues.

    No, I am not using any Asmedia ports for drives. The only drive I have is an NVME m2 SSD.

    Things have been stable for a couple days since disabling WiFi power management. Will keep this thread open for a few more days to confirm
