rolling is trying (and fails) to load the (i believe correct) driver
dms | grep 802 returns:
cfg80211: calling CRDA to update world regulatory domain
iEEE80211 ĥy0: brcmsmac: fail to load firmware brcm/bcm43xx-0.fw
iEEE80211 ĥy0: brcmsmac: Failed to find firmware usually in /lib/firmware/brcm
it seems to be the driver loaded by ubuntu to make it work
