Public bug reported:
Ubuntu version 20.04.1 LTS (was previously running 18.04.4 LTS and upgraded to
try to resolve this issue)
Intel Corporation Wireless-AC 9260
Problems with WiFi connection slowly grinding to a halt. From /var/syslog (see
attachment for further info from the log):
Microcode SW error detected. Restarting 0x2000000.
This occurred first a couple of days ago presumably following an update. The
logs /var/log/syslog and /var/log/kern.log filled up with the disk repeated
attempts to restart the WiFi.
I upgraded to the latest release of Ubuntu hoping to fix the problem. Also
worth mentioning that I don't think its a hardware problem as wiFi works when I
boot up from a USB pen drive.
** Affects: linux-firmware (Ubuntu)
