[SOLVED] Zorin 6.3 & WiFi

So my problem - I can't get WiFi. There's no icon on the taskbar but when I turn the laptop on, a pop-up stated "disconnected" with what looks like the WiFi icon next to the words.
Ethernet has no problem & there's nothing found when I check for additional drivers.

I found the following code:

lspci -nn | grep 0280
lsusb
lshw -c network
sudo rfkill list all

The result is:

Any help please?

Hi,

I am not an expert on this one (where is MV when you need him?) but I think you need to install the package with the following terminal command and it should work afterwards:

Code:

sudo apt-get install firmware-b43-installer

Regards Wolfman

Your card is BCM4318. According to the broadcom wiki, this card uses the b43 driver (as WM correctly stated). The problem you have is that your system has loaded by default the wl driver and creates a conflict.
So we need first to remove the wl driver and then install the b43 driver.

Plug an ethernet cable on your pc and run the following 3 commands:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43

I have a Broadcom 4311 wireless card and the B43 drivers do not work correctly.

The only way to get my wifi to work is install this firmware.

Code:

sudo apt-get install linux-firmware-nonfree

And even then the wifi is very buggy, drops out and takes several minutes or even a reboot to get the wireless working again. Wish Broadcom would release a driver package that did not require compiling.

Hi,

for the BCom 4311 model see this:

I have the bcm4311 as well (see my signature) and it works great. The same set of commands applies for bcm4311 as well.

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43


Make sure you have removed the bcmwl-kernel-source (1st command) as it conflicts with b43.

Hi, all is well but after entering 'sudo modprobe b43', I pressed Enter and the green cursor moved down a line and nothing. How long do I wait? Trying to exit the terminal gives me a warning stating it's still in process.

Hi,

did you get any feedback from the modprobe command?, is it working anyway?.

I had to shut down, so I just closed the terminal, clicked the option to close it anyway & restarted.

I took a chance & after a restart ---

Thank you everybody!!!
