I'm running Ubuntu 14.04 and the Broadcom BCM43241 card in my vaio duo 13 doesn't even show up

Question

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 lspci I cant post pictures yet but here is the output lspci

Solution

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

Can you add the output of lspci anyway.

Please post the output of the following: "lspci -nn | grep Network"

Ok I edited it.

Are there any steps in addition to this one that I need to use?? Because I have put both files in the proper location, and it still doesn't work

How do you build/find/get the brcmfmac43241b4-sdio.txt file?
