How To Install Broadcom Wireless Drivers on Ubuntu

Ubuntu 15

In this article, we will guide you through the process of installing Broadcom wireless drivers on Ubuntu. Broadcom is a prominent manufacturer of wireless cards and many laptops come equipped with Broadcom cards. However, sometimes the drivers for these cards are not included by default in Ubuntu, which can cause connectivity issues. Let’s dive into the process of installing these drivers.

Quick Answer

To install Broadcom wireless drivers on Ubuntu, first identify your Broadcom wireless card model using the command "lspci -vnn | grep Network". Then, install the Broadcom STA driver by running "sudo apt-get install bcmwl-kernel-source". Reboot your system to activate the driver. If this method doesn’t work, you can try installing the b43 driver or compiling the driver from source.

Checking Your Broadcom Wireless Card Model

The first step in this process is to identify your Broadcom wireless card model. This can be done by running the following command in the terminal:

lspci -vnn | grep Network

The lspci command lists all the PCI devices in your system. The -vnn option makes the output more verbose and displays the vendor and device codes. The grep Network part filters the output to only show network devices.

This command will output information about your network devices, including your Broadcom wireless card if you have one. Look for a line that mentions Broadcom and has a model number that starts with BCM43, such as BCM4311, BCM4312, etc.

Installing the Broadcom STA Driver

Once you’ve identified your Broadcom wireless card model, the next step is to install the Broadcom STA (Station) driver. This driver supports most Broadcom wireless cards, including the BCM43xx series.

To install the Broadcom STA driver, run the following command in the terminal:

sudo apt-get install bcmwl-kernel-source

The sudo command runs the following command with root privileges. The apt-get install command installs the specified package. In this case, the package is bcmwl-kernel-source, which is the Broadcom STA driver.

After running this command, the Broadcom STA driver will be installed on your system.

Rebooting Your System

After the installation is complete, you should reboot your system to activate the driver. You can do this by clicking on the power icon in the top right corner of your screen and selecting “Restart”, or by running the following command in the terminal:

sudo reboot

Alternative Methods

If the above method does not work for you or if your Broadcom wireless card model is not supported by the Broadcom STA driver, there are a few alternative methods you can try.

Using the b43 Driver

Some Broadcom wireless card models are better supported by the b43 driver. To install this driver, run the following command in the terminal:

sudo apt-get install firmware-b43-installer

After running this command, the b43 driver will be installed on your system. You should then reboot your system to activate the driver.

Compiling the Driver from Source

If none of the above methods work, you can try compiling the Broadcom driver from source. This method requires more advanced knowledge of Linux and is generally not recommended for beginners. Instructions on how to compile the driver from source can be found on the Broadcom website and on various community forums.

Conclusion

If you continue to experience issues, you may need to seek further assistance from the Ubuntu community or Broadcom support. Remember to test your wireless connection after the installation to ensure that it is working properly.
