Just want to mention that the sticky boradcom workaround
https://forums.opensuse.org/showthread.php/484106-Broadcom-firmware-is-needed-for-b43-but-I-have-no-network-an-easierwork-aroundleeds to a very slow wifi connection on my acer laptop with BCM43227.
I could not find the reason. However deleting the downloads and going the usual way by installing the packman drivers broadcom-wl and boradcom-wl-kmp brought back fast wifi.
