Tutorial on installing bcm43142 wireless network card driver in Ubuntu, javastubcm43142

Due to learning needs, I installed Ubuntu dual-system, but various configuration problems also followed. The most speechless is the bcm43142 NIC Driver Installation.

This is an old network card, and its driver cannot be found on the official website !!! Therefore, you can only collect various tutorials online. In general, you can use the following two methods.

First: Use Ubuntu software and updates

The Ubuntu Desktop version has software and updates for this application. Here we can install the driver we need, as shown in. Select the driver in the Broadcom column, and click application change. The driver will be ready for a while. Then you can see that you can connect to the Wi-Fi network. If not, restart your computer.

Method 2: Use the command line

For Ubuntu systems without a desktop, or users who cannot find the above software, you can directly use the following command to install the NIC Driver, which is very simple.

Sudo apt-get install linux-headers-generic build-essential dkms

Sudo apt-get update (optional maybe)

Sudo apt-get install linux-source

Sudo apt-get install -- reinstall bcmwl-kernel-source

Sudo modprobe wl

After running the preceding command, you can connect to the Wi-Fi network. If not, you can restart your computer.

The above are two simple ways to install the BCM43142 NIC Driver.
