I have tried all the known solutions and it still won't work. I have tried the brcm modprobe after updating the firmware library as well as doing the blacklist thing for bcm43xx. Is there a fix for this??
——-edit——
The lspci -nn command wouldn't do anything

you must copy the file called brcmfmac43241b4-sdio.txt to /lib/firmware/brcm where it accompagnies the driver called brcmfmac43241b4-sdio.bin.
Normaly this is created using nvram-tools but it does not work on the sony pro 13 and I copied one from the net. Your can download one from the net
