How to Install the BCM43142 WiFi Driver on Kali Linux

How to Install the Broadcom BCM43142 Driver on Kali Linux - In this article, I will explain the steps to install the Broadcom BCM43142 802.11b/g/n driver on Kali Linux. If you install Linux on a laptop that uses the BCM43142 chipset, the wifi driver will not automatically activate, which means you have to install the wifi driver manually so that the wifi on your laptop can be used.

From my experience using a laptop with a Broadcom BCM43142 chipset in several other Linux distributions such as Arch Linux, Manjaro, Debian and of course Kali Linux, this chipset does not yet support. Therefore I have to outsmart it so that the wifi chipset can function normally.


How to install the BCM43142 wifi driver on kali linux

To install the BCM43142 driver on Kali Linux, you must first update the repository and upgrade the package by typing the following command in the terminal.

# apt-get update && apt-get upgrade
Now please install linux-headers and build-essential by running this command in the terminal.

# apt-get install linux-headers-$(uname -r) build-essential -y
Wait until it's finished, when it's finished installing linux-headers, now install the synaptic package manager because we will install the driver using synaptic.

# apt-get install synaptic -y
Then run the Synaptic Package Manager by typing the synaptic command in the terminal, click on the Search menu, then in the Search column please type BCM43142.

After rebooting your laptop, please log in again and now you can use wifi in the kali linux you use.

Update !!!
After a long time I used the Kali Linux distribution on my laptop that uses the BCM43142 wireless chipset, I found some shortcomings even though wifi can be used without any constraints, here are some of the shortcomings that I found.

  • It does not support running mdk3 to disconnect other users on the network.
  • It does not support monitor mode so we cannot capture handshakes when penetrating a WiFi network.
  • Cannot run aircrack-ng software, which is a software used for wireless network penetration.

    The conclusion is, although you can run wifi on kali linux on a laptop that has a BCM43142 wireless chipset, you can't use it for penetration and testing purposes that require wifi such as disconnecting other users, capturing handshakes, running monitor mode, sniffing, etc.
