Ubuntu – “No Network Devices Available” for BCM43241(SDIO) after fresh install of 13.10


I have a laptop vaio duo 13 which has a broadcom 43241 wireless card. My problem is similar to this one Broadcom Wi-Fi Adapter not recognized .

I tried to install the driver brcmfmac(SDIO) here http://wireless.kernel.org/en/users/Drivers/brcm80211 and copied the nvram to /lib/firmware/brcm as the page tells, but this didn't work.

Most questions I searched are about br43 such as Installing Broadcom Wireless Drivers . I tried part of solution like unblock all in rfkill, put an # in front of blacklist bcm43xx, but none worked. I didn't uninstall or install any drivers such as b43-installer, b43legacy-installer, bcmwl-kernel-source (only tried b43-fwcutter) because they are not compatible with bcm43241.

Above is all information I can provide for help. Thanks.

Found in the question, written by the OP.

After contacted a developer of broadcom, he gave me mails between him and an user who had same issue but have successfully solved this. The user helped me by sending another nvram and firmware (a bin and a txt) and it worked. I think it's just because the wireless card is too new for the current kernel (correct me if I say something wrong as a novice of linux).

I attach them here


copy them to /lib/firmware/brcm and execute sudo modprobe brcmfmac-sdio, the problem solved.
