[SOLVED] Broadcom Wifi network card not working

seth · 2022-02-26 16:25:32

BTW, output #21 is archiso again.

Sounds like a bug in the install iso that would explain pretty much everything.
Please check the output of the command in #24 on the iso.

If Garuda Linux is Arch-based, and driver works on Garuda Linux, by using the same logic, shouldn't the drivers also work on Arch Linux?

https://en.wikipedia.org/wiki/Syllogistic_fallacy
The kernel module cannot work if it's not present itfp. and neither "garuda" nor "arch" is a thing (because the package and kernel versions would matter) and the driver works wrt the kernel, not some distro.
And broadcom-wl isn't an AUR package, btw.

Shouldn't it have solved if I were to install it from another server?
I tried using different servers to download the iso.

During the live boot, which kernel does Arch Linux use? Is it the LTS version? The zen version?

Thanks for everything up until now, man. Really appreciate it if you could solve my problem.

Hope you have a good day =)

No. It'd be the iso, not your copy of it.
Please post the output of the command in #24.

It is as it is, after all its the live installation.

/usr/lib/modules/5.16.11-arch1-1/extramodules/wl.ko.xz

Linux archiso 5.16.4-arch1-1 #1 SMP PREEMPT Sat, 29 Jan 2022 19:08:13 +0000 x86_64 GNU/Linux

local/linux 5.16.11.arch1-1
The Linux kernel and modules

If this is all still on the iso, running the 5.16.4 kernel, but the only wl module is installed for 5.16.11, matching the installed but not the running kernel, it's no wonder that it's not working.

This all kinda doesn't add up - I'm sorry, but I'm totally confused about the circumstances you're running these commands under.
Do you somehow chroot into an installed system?
Why is the kernel package on the iso 5.16.11 but the booted kernel is 5.16.4???

ShamUsesArch · 2022-02-27 15:14:58

Oh, I see, let me explain. I had the older arch linux installed, of which the grub was broken, so I could not boot in. What I usually do is use the older installation (which does not have the grub installation) for my convenience to be able to store the output. I mount the partition and then chroot to the system. After chrooting, I run pacman -S broadcom-wl to install the drivers. The live installation is fairly new.

For now, I have deleted all the OSes present on the PC. What would you like me to do? I can do any of them.

I could install arch linux using USB ethernet or stay on the live installation.

Thanks for your time

Boot the iso.
Do *NOT* chroot anywhere.

Obtain the outputs of

uname -a
pacman -Qs 'linux|broadcom'
pacman -Qlkk broadcom-wl
modinfo wl | head
lsmod
lspci -k
modprobe -v wl
ip a

In that order.
You can still create/mount some partition filesystem (or attach a second usb key or whatever) to store the data, but do *NOT* chroot away from the iso.

ShamUsesArch · 2022-02-27 15:29:22

No installing/updating broadcom-wl drivers?

seth · 2022-02-27 15:38:04

They're supposed to be on the iso and I want to see the vanilla status.

The package is there and intact and the kernel module therefore available, but not used for the chip (though considered)
You didn't post the output of "lsmod" but the empty "modprobe -v" output at least *suggests* that the module is already loaded.

Boot the iso, do *not* chroot anywhere but

modprobe -rv bcma wl # unload bcma and wl
modprobe -v wl # load the wl module
rfkill
ip a

Man, I really appreciate helping me out and sticking with me all this while. I did try unloading and loading the modules even before I posted this but to no avail. Seems like I would update the broadcom-wl package everytime.

The rest is just to connect to the internet using wpa_supplicant, right?
Please correct me if I am wrong :D

Hope you have an awesome day =)

seth · 2022-02-28 06:59:38

I guess you were simply trying to reload the modules after chrooting into the existing system.
In case that's still an open question: I think the iso now uses iwd by default but assume wpa_supplicant is still available and will get the job done as well.
