[Solved] No Wifi After Fresh Installation

Hello All,

I am new to Artix Linux as well as to this forum. I have a Dell Inspiron 1545 laptop with Windows 10. I installed Artix LXDE runit in it. I made a bootable usb and booted using it. I first setup the wifi as I don't have ethernet cable. USB media recognised the wireless driver and the set up was pretty straight forward. After it the installation was absolutely easy and fast.
But when I rebooted into the new installation, it couldn't find the wireless anymore. I am posting this from another laptop. Here is some system information.

I am new to Artix Linux. Please help.

Thanks.

What say lsmod and dmesg? Put here both logs please.

Read this :

https://wireless.wiki.kernel.org/en/users/Drivers/b43
https://wiki.archlinux.org/index.php/Broadcom_wireless#Installation

and

https://bbs.archlinux.org/viewtopic.php?id=198246

Old broadcom wifi cards was pieces of sh*ts, because broadcom not cared about Linux. First in 2010 came opensource driver.

Try use first brcm80211 driver, if not help, use b43 driver with his firmware, as wrote archlinux wiki

Try this,

Code: [Select]
sudo pacman -S linux-headers base-devel broadcom-wl-dkms

After the installation , reboot your system.

Nothing happened.

I forgot to mention, there is no wireless option in the Network Setting. Only "Wired" is listed there.

Thanks.

Can you post
Code: [Select]
lsmod

again?

Also,
Code: [Select]
iwconfig

You need to install wireless_tools first.

Did you check if rfkill blocks the wireless device?

Code: [Select]
rfkill list

Nothing is there under rfkill list.

Thanks.

Is it in the USB installation media? Because, when I started the installation I configured the wifi first. Only after the installation I couldn't connect it anymore.

https://bbs.archlinux.org/viewtopic.php?id=198246 links works for me good.

I tried
Code: [Select]
#pacman -S b43-firmware

Didn't work. So I did -
Code: [Select]
git clone https://aur.archlinux.org/b43-firmware.git
makepkg -s
sudo pacman -U b43-firmware-6.30.163.46-1-any.pkg.tar.zst

Reboot. No wifi.

lsmod : http://sprunge.us/qlqGJR
dmesg : http://sprunge.us/i5PKVL

ok, so begin with kernel opensource driver:

Code: [Select]
modprobe brcmfmac

 has anything changed in lsmod and dmesg?

Code: [Select]
sudo modprobe brcmfmac

Reboot. No wifi.

lsmod : http://sprunge.us/qvc4Yh
 dmesg : http://sprunge.us/lk15Kk

if NOT, install please https://aur.archlinux.org/packages/b43-firmware-classic/

Edit:  because if not, you will need probably  "older" driver b43


Again I tried with 
Code: [Select]
#pacman -S b43-firmware-classic

Didn't work. So I did -

Code: [Select]
git clone https://aur.archlinux.org/b43-firmware-classic.git
makepkg -s
sudo pacman -U b43-firmware-classic-5.100.138-1-any.pkg.tar.zst

Reboot. No wifi.

lsmod : http://sprunge.us/PRVDr5
dmesg : http://sprunge.us/MxW0oB

So now, what should I do?

Thanks.

1. i wrote you clearly, do not use/install b43-firmware!
Code: [Select]
pacman -R b43-firmware
2. do you load b43 driver?
Code: [Select]
modprobe b43

i don't think so because there is no b43 module in lsmod (http://sprunge.us/PRVDr5).
