At the suggestion of fire219, I tried downgrading my wireless firmware (the ap6256-firmware package) from version 2020.02 to 2020.01. If you want to try this yourself, fetch the package from here:
http://ftp-nyc.osuosl.org/pub/manjaro-ar...pkg.tar.xz
http://ftp-nyc.osuosl.org/pub/manjaro-ar...tar.xz.sig
(If the repo should stop supplying this version, I've also attached it to this post. You should check the signature before installing packages from strange sources like this, though.)
The result:
- 5-GHz wifi is now reaching speeds characteristic of 802.11n (~100 Mbit/s), but only intermittently, and only in the downlink direction.
- 2.4-GHz wifi is still working pretty terribly.
Firmware is weird. So is Broadcom.
