Did a little more digging in my old logs. I think I found kernel logs from my zesty install. iwlwifi firmware jumped from v22.391740.0 up to v31.532993.0 (probably during upgrade). Shortly after that is when I experienced the first 'Microcode SW error detected'.
Would it be worth me reverting back to v22 and trying that? I'm definitely a n00b when it comes to kernel/firmware stuff. Not sure how it all works. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1732057 Title: WiFi Microcode SW Error Detected Status in linux package in Ubuntu: Incomplete Bug description: Did a fresh install of Artful on my System 76 daily-driver laptop and I've been having an issue where my WiFi randomly stops working. The Gnome desktop doesn't report the wifi loss. NetworkManager doesn't report any error. The only error is the following dmesg log (see attachments). I can fix it temporarily by manually reconnecting to the wireless network I was using.
