Comment 7 for bug 1776443

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".
