Joseph... I also thought I had mentioned this a quite a new machine, so
it doesn't have a lot of history. However, I had a similar wifi failure
quite often with the latest 17.10 kernel before the upgrade to 18.04.
I will look for a 17.10 log if you think it would be helpful, but I'm
not sure I kept any.
More importantly, and more hopefully, I will try to install an upstream
kernel as you suggest.
I am certain of two things:
1. I have tried every version of iwlwifi from 29 back to 17. I'm pretty
sure the older firmware packages would not work with my hardware and
kernel versions.
2. If I blacklist iwlwifi and use a dongle with Realtek wifi adapter,
the problem does not occur.
Although it is possible this is a kernel or driver bug, my guess is we
are dealing with a firmware bug. The Intel support page for this driver
says:
"Having Wi-Fi and Bluetooth running at the same time is a challenge."
I am sure you will let me know if I can collect any other useful
information, either before the failure, or after. In the meantime, I
will follow the instructions by marking this bug "confirmed".
