I have run it (wireless) by ummmm let's see if I can find it...................o.k. here:
This works but it would be better if I knew what it meant and I need a way to save it on a live stick....still hampered by home wireless being down. Awkward with a hotspot. (Samsung S3)
Make sure you have /lib/firmware/brcm/brcmfmac43241b4-sdio.bin
If not already mounted : "mount -t efivarfs none sys/firmware/efi/efivars"
cat /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 > /lib/firmware/brcm/brcmfmac43241b4-sdio.txt
modprobe -r brcmfmac && modprobe brcmfmac
Ready!!
