WiFi unavailable after computer suspend

[David Arnstein]

I believe that this issue is specific to Intel AX1650i WiFi chip.

After suspend and resume, WiFi is no longer available. The Gnome UI indicates computer is in airplane mode. Rfkill(1) reports that networking is blocked in hardware.

I have an output from apport that I made right after suspend and resume. I will attempt to attach it to this bug report.

I saved /var/log/syslog after suspend and resume. I see that the system failed to load firmware into the AX1650i chip. I will attempt to attach this file to this bug report.

In this attachment, you can see suspend and resume. Shortly thereafter, you can see that the system failed to load firmware into the AX1650i WiFi chip.
