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 How to Install Broadcom Wireless Drivers (BCM43xx) . 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.

The card uses a momentary switch to turn on at and off and it doesn't work. I read that there is a way to have the card turn on by default on boot but I can't figure out how to do it. Any help is appreciated. >>> More
