How to Install Broadcom Wireless Drivers for BCM4360 Chip on Kali Linux

====================================================================================

Introduction

---------

If you're a seasoned Linux user, particularly those who have transitioned from other operating systems like Windows or macOS and are now using Kali Linux as your primary distro for various reasons (perhaps due to its robustness in penetration testing tasks), you might encounter some challenges when trying to get the built-in wireless drivers working. One such scenario is when dealing with Broadcom chipsets, specifically the BCM4360.

In this article, we'll walk through a step-by-step guide on how to install and configure the necessary proprietary drivers for your Broadcom Wireless card (BCM4360) under Kali Linux so that you can enjoy seamless connectivity without any further hassles.

Prerequisites

----------

Before diving into the installation process, ensure that:

1. You have an older Broadcom chip supported by the b43 driver.

2. The package `b43-fwcutter` is installed on your system.

3. Your computer has a working internet connection (preferably via Ethernet or any other wired interface) since you'll need to download some necessary files.

Step 1: Enable Non-Free Components

--------------------------------

First things first, we need to enable the non-free component repository in aptitude so that we can install proprietary drivers:

```

sudo apt-get update -y && sudo apt-get dist-upgrade -y

# If using kali-rolling or sid-based systems:

echo 'deb http://mirror1.lonelysolutions.com/kali-dev/old-stable main' | sudo tee /etc/apt/sources.list.d/broadcom-wireless-newer-dkms-lts-squeeze-backports.list

sudo apt-get update -y && sudo apt-get install broadcom-wireless-new firmware-b43firmware-legacy bcgmwlagn-dbg b43-firmware-realtek firmware-brcm80211 broadcom-sta-hmac-modules-4.6.7-2-amd64-signed broadcom-wgasapi # Replace with the correct version number if needed

```

Step 2: Reboot and Verify

----------------------

After enabling the non-free repository, reboot your system to apply all changes:

```

sudo shutdown -r now

```

Once you've logged back in, open a terminal window (if it's not already open) and execute the following command to verify that the Broadcom STA driver has successfully loaded:

```bash

lsmod | grep brcmwl || apt-get install broadcom-sta-dkms firmware-b43-legacy firmwares-nonfree && reboot -n1 ; lsmod | grep brcmwl

```

Troubleshooting Tips:

----------------

If you're still encountering issues after following these steps, here are some additional troubleshooting tips to keep in mind:

* Ensure that the Broadcom STA driver is properly installed and loaded by running `lsmod` or checking dmesg logs for any error messages related to brcmwl.

* If you've previously attempted to install proprietary drivers via other methods (e.g., using the apt-get package manager directly), try completely removing them first before retrying with our approach.

-------

That's it! With these simple instructions, you should now be able to successfully install and configure Broadcom Wireless Drivers for your BCM4360 chip on Kali Linux. Remember always to keep your system up-to-date by regularly running `apt-get update` followed by an upgrade command (`sudo apt-get dist-upgrade`) whenever new kernel versions become available.
