ASUSTeK BCM4366 [14e4:43c3] stopped working

[Zukas]

On Ubuntu 22.04, after recent update WiFi card stopped working. However, when using an Ubuntu install disk the WiFi card is properly detected, but when installation completes (with updates) WiFi is inaccessible again. After an update to Ubuntu 22.10 the issue persists:

This change was made by a bot.

[Stephan Oehlert (soehlert)]

The issue appears to be with the brcmfmac driver, which isn't working for me either.

The last kernel version where the driver worked properly was 5.19.0-38 (Ubuntu 22.10).
