Getting proprietary WiFi drivers to work in GNU/Linux distros can be a pain sometimes. This time we’re going to deal with such a proprietary driver for the Broadcom BCM43142 WiFi device. Let’s take a look at how to install WiFi driver for Broadcom BCM43142 WiFi device in popular GNU/Linux distros such as Debian, Ubuntu, Fedora and Arch Linux. First of all let’s make sure we’re having the Broadcom BCM43142 WiFi device. For that let’s make use of the lspci command as follows:

lspci -nn | grep -i network

The advantage of using a dkms driver is that you don’t need to manually update the driver everytime you upgrade your kernel!

Dynamic Kernel Module Support (DKMS) is a program/framework that enables generating Linux kernel modules whose sources generally reside outside the kernel source tree. The concept is to have DKMS modules automatically rebuilt when a new kernel is installed.

  1. Ok. I don’t want to be rude nor insulting…..but has no one considered, that if you’re able to UPDATE and INSTALL anything then you’re ALREADY CONNECTED? and thus activating the wifi is not much of an issue? What about when you CANNOT CONNECT to your wifi?…how are you supposed to “apt-get” ANYTHING!? I do wish that sometimes the folks who write articles would be more considerate of the newbie who is not familiar with Linux! Is there an article where someone can find out how to install this if they DON’T have wifi!?

  2. This procedure fixed my problem so I consider it a godsend. I guess they did forget to say plug in an ethernet cable and do the apt-get, but very few people wouldn’t know to do that.
