Install a Wi-Fi driver on Ubuntu

At one point in the document you sent me, it says:
" 2.1 Native Linux driver from Broadcom (Broadcom STA wireless driver)

Broadcom provides a driver named Broadcom 802.11 Linux STA driver.

This driver supports the following cards: BCM4311, BCM4312, BCM4321, and BCM4322.

The module is integrated into the Linux kernel in version 2.6.24-21, under the name wl (requires blacklisting b43 and ssb. However, be careful, if your ethernet card uses b44, ssb is required, and in that case you will not be able to use this driver.)

Zoltan, it's because on your Ubuntu, the package manager is not installed. Here’s what you need to do: Look in Activities or Applications and System Tools for "Ubuntu Software" and open it. Then, in the search bar, type "synaptic" and request the installation of the Synaptic package manager. When it is installed, open it and search for "network manager wifi"; you will get a list of packages and install all the ones that are not already installed... and it will work!

Me, I read

Now the installation is done via the proprietary driver manager under the name of "Broadcom STA wireless driver", and the operation is completely improved.

In my opinion, there is nothing else to do

Re
I am a bit of a novice in Linux
Could you please tell me how to do it?
Thank you very much

You open the package manager and in the search, you enter:
network manager wifi
and you install all the packages from the list (there aren't many) and it should work.

Thank you very much, I'll take a look at it.

However, when I go to system settings > Additional drivers >
I see the Broadcom STA Linux driver, but I cannot connect to my Livebox via Wi-Fi, whereas when I was on Windows on this PC, I could connect without any problem.

I am attaching screenshots of the network and additional driver windows

Hello,
this is not what it says to do, but to go to the program installations to install the driver
before going into the connection

There is no "Enable wireless network", there is only "Enable network"

As for the result of the iwconfig command, here it is:

lo no wireless extensions. eth0 no wireless extensions. 

Hello,
Are you on Debian?
I installed ndiswrapper for driver support when there is no driver available for Linux to install a WiFi card.

But how can I enable the wifi then?

Manually install the driver:

sudo apt-get install b43-fwcutter firmware-b43-installer

Then go to "Additional Drivers" to activate it.

Finally, restart your PC and it should be good.
