If you are having problems with your wifi Broadcom bcm4311 drivers as I did, you may follow these steps below.

  • Verify your BCM Netwok Controller:

lspci | grep BCM

  • If you have package bcmwl-kernel-source installed, it will be necessary to remove it:

sudo apt-get remove bcmwl-kernel-source

  • Install firmware-b43-installer and the b43-fwcutter packages:

sudo apt-get install firmware-b43-installer b43-fwcutter

  • Verify if your bcm hardware is blacklisted. Run the command below:

cat /etc/modprobe.d/* | egrep ‘bcm’

  • If you see ‘blacklist bcm43xx’ there, it means its blacklisted.
  • Remove it from blacklist by editing the conf file

sudo gedit /etc/modprobe.d/blacklist.conf

  • Comment the line putting a # in front of the line: blacklist bcm43xx. Save the file.
  • Reboot your pc.
  • Confirm your wifi is not blocked.

rfkill list all
