No wifi while using my broadcom wireless adapter

Please provide the output for,

sudo lshw -C network

The first step is to remove any broadcom drivers already installed on your system. Open a terminal and use the following command:

sudo apt remove broadcom-sta-dkms bcmwl-kernel-source

If you are connected to internet via LAN/Ethernet cable, you can install different broadcom drivers using this command:

sudo apt install firmware-b43-installer

If you don’t have ethernet, you may still be able to pull this off. But you’ll need another system (Linux, Windows or macOS) with active internet connection.

What you are going to do here is to download the driver manually and then transfer it to your problematic Linux system and install it there.

Download both the Drivers from these Links,
Link 1
Link 2
You can use the dpkg command to install the package from deb file.

cd ~/Downloads
sudo dpkg -i b43-fwcutter*
sudo dpkg -i firmware-b43-installer_*
sudo reboot

This Should Solve your Problem. Theoretically :man_scientist:


I do not use Ethernet. I will install the drivers from my notebook and install.

My wifi is working again, But, I will notice any further bugs for while.
