[SOLVED] wi-fi won't show up

Hello,

It's my first time installing arch, and no matter what I try, I cannot get the wifi to work.
I am trying to install the 6.4.12 version, and I'm running Dell Inspiron 15 3878.
After loading into the live environment, when I run `iwctl device list` like the wiki says, no device is listed. I tried some solutions but there weren't many for the installer so I decided to go along with the installer using a wired connection, and try to fix the issue after installing. The rest of the process went flawlessly, I don't know what info to provide about the installation process so I'll just say that currently I have linux-hardened version of the kernel installed, but I've tried the regular linux kernel and the issue persists. Now, after booting the issue persist. I tried using different network managers, but it's the same issue. I tried installing lsusb, the broadcom-wl driver (broadcom-wl-dkms too), linux-headers, basically everything I could find on the internet - I've tried. I really tried my best, but I am completely hopeless at this point. I have no idea what info to provide, but please help me out, I am desperate.

Sorry, but I don't know how to get the output in text format without an internet connection. Although wired connection works in the installer, it stops as soon as I reboot. Hope the picture is enough.

Re: [SOLVED] wi-fi won't show up

I already installed it and it doesn't fix the issue

Installed "it". What, exactly?

Is the module actually loaded?

Re: [SOLVED] wi-fi won't show up

You can post the journal of the installed system from a the installation iso:
https://wiki.archlinux.org/title/System … al_to_view
http://wiki.archlinux.org/title/List_of … n_services

Make it "-b" instead of "-e"

Re: [SOLVED] wi-fi won't show up

Well, I booted the live environment, mounted my disc, arch-chroot into it and ran:

pacman -S broadcom-wl-dkms linux-headers base-devel

I don't see anything other than that in the documentation, so I assumed that it's enough

There's a precompiled module for the main kernel, otherwise you'll still have to build the module.

I got this output: ix.io/4Fjd

Re: [SOLVED] wi-fi won't show up

Why would you install linux-headers when you're using linux-hardened, not linux?

Re: [SOLVED] wi-fi won't show up

The wiki said "will need the linux-headers package for the installed kernel(s) in order to build the module. Those packages are optional to the DKMS package and will need to be installed manually.", and I don't know how to interpret it."Those packages are optional to the DKMS " sound like I don't need them and "will need to be installed manually" sound like I need them, so I decided to just install them either way.
But does it do anything if I have a package that I don't need? I mean, I know I should keep my system clean and all, but it doesn't have to do anything with my issue, doesn't it?

You want/need linux-headers if you have the linux-kernel

Did you read the DKMS wiki?

Sorry, I missed your previous message. After reading the wiki turns out I have to install both linux-headers and linux-hardened-headers, after doing so and running dkms-autoinstall, iwctl finally showed my wifi. I tried connecting to it using the built in dhcp client in iwd but it didn't work so I installed dhcpcd and it works now. I have no idea how in my 22 hours of googling I didn't see the dkms wiki once, my fault. Thank you for your help.
Also, is iwd + dhcpcd a good enough setup, or is there a better way of handling the connection? I've seen many other solutions and every post says different things. After installing the drivers the wifi seems to be detected by the other network managers too.

Re: [SOLVED] wi-fi won't show up

iwd can do dhcp itself, https://wiki.archlinux.org/title/Iwd#En … figuration

What you use to configure your network largely depends on task complexity (a single static ethernet connection basically needs nothing, if you jump between mobile APs, you might want a bit more convenience) and personal preference (do you want a GUI, do you want your autoconnections to be hyperactive,  etcetc.)
=> https://wiki.archlinux.org/title/Networ … k_managers
There's no "correct" answer to this, diverse solutions exist because of diverse needs and preferences.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
