WiFi cut out

I've been facing WiFi issues in ElementaryOS since I updated my system about a week ago. When I turn on my computer it is able to connect to WiFi, but after a while it simply stops recognizing all modems (including the one I use).

I have reasons to believe the issue at concern has something to do with the system updates I mentioned. When the issue first emerged I thought I had messed something up by deleting some gpg keys. Then I backup-ed my files and reinstalled Elementary from the ground up (formatting the old partitions and everything). Everything was working fine, until the AppCenter prompted me for a system update and I installed it. Now I'm facing same issue again.

I'm running ElementaryOS Hera in a Lenovo ThinkPad E490. I've attached `dmesg` and `lspci` logs to this bug report too. Let me know if you guys need any additional information.
