@Emmanuel: We generally only update firmware in stable releases in
response to specific issues, as new firmware sometimes introduces
regressions. Besides, ucode version 34 is the newest supported in the
4.15-based kernel in 18.04.
@UrkoM: When you say wifi used to be stable, was that prior to upgrading
to bionic? Because the firmware version you're using looks to be the
same one that bionic released with, so there were no updates which could
have caused regressions.

Title:
iwlwifi Microcode SW error detected. Restarting 0x2000000.
Status in linux-firmware package in Ubuntu:
Incomplete
Bug description:
This seems to be a return of an existing bug, in newer hardware and
microcode versions.
Wireless card: Intel Corporation Wireless 8265 / 8275 [8086:24fd] (rev 78)
Firmware version: 34.0.1
Description: Ubuntu 18.04.1 LTS
Frequent errors as soon as I connect to wifi:
Microcode SW error detected. Restarting 0x2000000.
Expected to happen: Great and stable wifi like a couple of weeks ago
What happens: very slow, intermittent internet access, lots of ping loss
Found a suggestion of a workaround: adding these lines to
/etc/NetworkManager/NetworkManager.conf
[device]
wifi.scan-rand-mac-address=no
These lines were already there, not added by me.
