Wifi issue

nnriyer · June 10, 2020, 4:57pm

In my laptop WiFi is not working. How to install b43 wifi firmware. I need simple solutions.

mlayland · June 10, 2020, 6:50pm

My guess is you would do something like this from a terminal.

yay -S b43-firmware

I hope that gets you what your looking for
Its in the AUR

nnriyer · June 11, 2020, 8:43am

I have done. No use. I have also some other operation after googling

sudo pacman -S base-devel git
git clone https://aur.archlinux.org/b43-firmware.git
cd b43-firmware
makepkg -sic

nnriyer · June 11, 2020, 8:45am

This command also applied and rebooted. Still not getting wifi

sudo pacman -S broadcom-wl-dkms linux-headers

ricklinux · June 11, 2020, 10:36am

You already installed the headers dkms version? Maybe blacklist wl

nnriyer · June 11, 2020, 10:43am

how to blacklist ?. See I am only layman. Please given simple solution. At last I have installed yay -s b43 -firmware classic and rebooted. Still no wifi/

ricklinux · June 11, 2020, 1:29pm

You could try this.
rmmod wl
modprobe b43
Note:

BCM4306 rev.3, BCM4311, BCM4312 and BCM4318 rev.2 have been noticed to experience problems with b43-firmware . Use b43-firmware-classicAUR for these cards instead.
BCM4331 noticed to have problems with b43-firmware-classic . Use b43-firmwareAUR for this card instead.

nnriyer · June 11, 2020, 1:58pm

I have applied above commands. Still not detecting Wifi Driver?
How to install b43-firmware-class and b43-firmware as given in your Note. Please pardon me for troubling you.

ricklinux · June 11, 2020, 3:49pm

Try installing it with yay.

yay -S b43-firmware-classic

Press enter for all

ricklinux · June 11, 2020, 11:49pm

@nnriyer

Not sure if you’ve got this working?

ricklinux · June 12, 2020, 1:40am

The BCM4312 should either work with the kernel modules b43 or with the broadcom-wl-dkms. So did you install the b43-firmware-classic? Did the install work?

Lets try removing the broadcom-wl-dkms and see what happens.

sudo pacman -R broadcom-wl-dkms

Reboot and then post the output of these commands from the terminal.

lspci-k

and also

lspci -vnn -d 14e4:

When posting the output you can copy and paste the output from the commands here and put three ~~~ symbols before and after what you paste here.

Edit: If you look at this post here and read through you will see it is the same BCM4312 chip and i got it working with the broadcom-wl-dkms by removing the b43 firmware so well see…

sudo pacman -S broadcom-wl-dkms linux-headers

below question not asked while doing trying above command

and say yes to question…

Remove broadcom-wl? [y/N]

I have also run below command
$ yay -S b43-firmware

Still Wifi not enabled !!!.

ricklinux · June 12, 2020, 9:50am

remove b43 firmware (If you have the classic version installed then remove it)

yay -R b43-firmware

Install broadcom

sudo pacman -S broadcom-wl-dkms

ricklinux · June 12, 2020, 10:00am

Let me know if this works or not.

nnriyer · June 12, 2020, 10:03am

Sir sorry to inform you that still not solved. Can you login to my machine through remote login. Is required to reinstall OS again. OS corrupted by trail and error method/

ricklinux · June 12, 2020, 10:08am

Did you reboot?
Try

rmmod b43 b43legacy bcm43xx bcma brcm80211 brcmfmac brcmsmac ssb wl

Then

modprobe-wl
