You’re right that it was power-related - one of the options was an ASPM modification - but the issue seemed to be common to this chipset accross laptop brands.
The fix I used came from this post: https://bbs.archlinux.org/viewtopic.php?id=286109
My machine was a Thinkpad, but this article was also talking about problems on HP, Asus, etcetera. I think the 8852BE might just be cursed
To be fair, I was using an E series Thinkpad, but in my defense, the E series seems to have improved a lot in the past few years - this was luckily the only issue I’ve had. I’ve had much more difficult times with Linux on other laptops. Heck, even my desktop had more setup than this when I was first starting out, though it was because I was using a Broadcom Wi-Fi card, as I also dual-booted with a Hackintosh and macOS only supports Broadcom Wi-Fi chipsets.
Also used it before, for Rounds I believe.
