I want to install Ubuntu on my Lenovo z51 Laptop. It has a Broadcomm bcm43162 Wifi Card.

When I boot into the Live CD, it doesnt have WiFi. When I go into the terminal and try:

sudo apt install firmware-b43-installer

It installs succesfully, but I still dont have a network connection.

A year ago I've managed to get it to work on my Ubuntu partition, but it got corrupted and I've forgotton how I did that.

I've tried Linux Mint, Manjaro & Ubuntu but they all don't seem to work.

Edit: Someone suggested: Installing Broadcom Wireless Drivers

But I've already stated that when I try

sudo apt install firmware-b43-installer

Nothing happens. And I can't reboot since I used the Live CD, because I want it to work first before I format my main partition.

  • When you check your device with lspci -nn, does it sat that firmware-b43-installer is correct for your device?

  • It cant even find it. E: Unable to locate package: firmware-b43-installer. Jan 10, 2018 at 13:47
  • According to lspci -nnk | grep 0280 -A3, and next referring to the duplicate, what is the correct driver for your device? I strongly suspect that it is NOT firmware-b43-installer.

  • Then what is? b43 firmware is the only thing that pops up if you search for my WiFi card on Google. Jan 10, 2018 at 14:15
  • Again, what does lspci -nnk | grep 0280 -A3 report??

1 Answer 1


try this:

sudo apt install firmware-b43-installer
sudo apt install net-tools
sudo apt-get install --reinstall bcmwl-kernel-source

It work for me

  • What is the ID of your card? The [14e4:43ae] is not supported by kernel or wl yet.
