I'm using Ubuntu on my Huawei Matebook HZ-W19.
My wireless card (BCM 4356) doesn't work with the latest version of linux-firmware (1.173.3) but works with version 1.156. Howerver, with this last one, my desktop glitches (Budgie, Gnome, Deepin, KDE).
So now I'm asking myself if it is possible to get the driver for the wireless card from 1.156 and to insert it into the 1.173 package.
Output from lsmod; dmesg | egrep -i 'brcm|firm'
