Hi!
I just installed (yesterday!) the correct firmware for BCM4311. But, you didn't say which distribution you are using.
If you, like me, use Debian you can follow this guide:
https://wiki.debian.org/bcm43xx
More specifically, you need to install firmware-b43-installer:
Code:
apt-get install firmware-b43-installer
Once installed, it will do the job for you.
If you do NOT use Debian (or any of its derivatives), check out this link for information on other distros:

Best regards,
