Problem
-------WiFi does not appear at all in Fedora. No problems with Ubuntu/Debian installs or Windows installs. This may be the wrong place to post this, but it seems this is the only place it wanted me to post, sorry if it’s wrong, just needed a little help from anyone more experienced with Fedora. It does seem to be a common issue, but none of the solutions have worked for me yet.

Only wired connection shows. Wired connection works fine, no problems there. Installed rpmfusion free and nonfree and a couple packages I read about but still no WiFi yet. There is one Broadcom package in dnfdragora that appears in search results but It can never seem to be installed. No errors, just always appears in the “Not Installed” catagory.

Cause
-----Perhaps no WiFi driver is installed for my laptop by default. I need to know the exact driver to install and where to find it.

Not yet known.

Workarounds
-----------The only workaround is to actually plug the laptop in to the router with a physical cable.

None yet.

This is correct. You need to install the proprietary driver for your Broadcomm hardware from RPM Fusion:

https://rpmfusion.org/Configuration

followed by

sudo dnf install broadcom-wl

Install the 50+ packages containing required build tools, kernel-devel-matched:
dnf install kernel-devel-matched akmod-wl
Automates build/pkg/install of wl kernel module when kernel is updated.

Sadly tried both of these things, along with some more similar things I found, but still no WiFi. I really appreciate the help though. It does seem that this is a common problem that many people have, and sometimes the steps above work, but sometimes for other people they don’t. Not sure why… Of course I fall into the category of people whose WiFi still doesn’t work. Is there any hope left, or is it just a thing and I’ll either have to live with it or install another distro for now?
Another post suggested posting the output of iwconfig, however that command is not found. There are still no WIFi connections listed, and no WiFi category. I am puzzled here. Thanks again for all your help, and for taking your time to read this.

That’s odd. The akmods take some time to build after the dnf command finishes (the RPM Fusion Nvidia page notes: “Please remember to wait after the RPM transaction ends, until the kmod get built. This can take up to 5 minutes on some systems.”

Could you please post the output of sudo fpaste --sysinfo --printonly please? I guess we first need to see if the device is recognised. If it is, we need to see why it won’t work. It’s also worth checking if your computer has a hardware switch for wifi. Sometimes this is automatically turned off and needs toggling.

Thank you very much Villy Kruse, that may be a solution. I haven’t seen that one before. I really couldn’t try it though because dnf can’t find any b43 packaged, either in terminal or gui. I did find a few pacages I could download directly from an Arch Linux repository I think it was, but would really like to get them directly from a Fedora repository if possible. Is that possible? How did you get them, did you just google and download directly, or is there another repository I need? I already have the rpm fusion enabled… Thanks again for your help!!!

Thank you so much for your assistance and help Ankur Sinha, I really appreciate any suggestions you can offer. First, WiFi IS working everywhere else on both Windows and Debian, so no problems there. As to the print out, it’s LONG, sorry about that! Anyway here it is:

I’ll try to read through that as well & see if anything jumps out at me. Just curious, is this a common thing with every release of Fedora? Thanks so much again for your help!

Okay, a new problem has presented itself. I don’t know how to get the information to you. First it kept giving me errors about how I’m only allowed 2 links as a new user. Didn’t know I even used one… Anyway, so I tried to save it to a text file, didn’t work. Tried compressing that text file, still didn’t work. It seems I’m only allowed to upload pictures. Thought I could fool it by renaming it from a zip to jpg and just telling you to change the extention but that didn’t work either, probably because it wants to actually display the picture. So… how can I get you the info you need? Sorry to bother you again and be a pain, I really do appreciate your help!

Don’t worry about those b43 packages for now. The important step is to install broadcom-wl which will pull in everything that is needed to build the kernel module, and also build it.

You alread have the instruction to do that. After that there will be additional instruction, but you first need to complete this instruction.

Thank you again for your help! Broadcom-wl has already been installed. That was my main problem, that I installed broadcom-wl but still didn’t seem to get anywhere. What are the next instructions?
PS. Here is my output from trying to install it again:

Last metadata expiration check: 1:04:04 ago on Tue 20 Sep 2022 12:05:08 AM EDT.
Package broadcom-wl-6.30.223.271-19.fc36.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!

Hey howdy!

I have a Broadcom wifi card and what helped me fix it was going here to the rpmfusion site: Configuration - RPM Fusion

And installing the following repos:

sudo dnf install rpmfusion-free-release-tainted
sudo dnf install rpmfusion-nonfree-release-tainted

Then I installed the b43-firmware and akmod-wl packages and that allowed my Broadcom card to function.

Hope it works for you!

Check if you have a signing key for the akmod modules

sudo file /etc/pki/akmods/certs/public_key.der

If you do, you should enroll that key in the MOK as described in the file /usr/share/doc/akmods/README.secureboot.

If you don’t, the same file have instructions on how to generate that key. Then run

sudo dnf remove kmod-wl\*
sudo dnf reinstall akmod-wl

Then find the generated wl module

find /usr/lib/modules/$(uname -r)/extra -type f

Then run modinfo with the name of the module as argument. It will show if the module have a signature or not.

Had a few other issues, the last one with dns, which are now resolved. Not sure how they happened… Anyway, upon checking, I get EFI variables are not supported on this system. Probably because my system is BIOS. The first command seems to confirm there is a key though. I cannot browse there with the file manager though, only as far as certs, then I have a permission error. AmI still missing something, or do the instructions change because I am using a BIOS system?

The second set of instructions were done and successful, the uninstall and reinstall, but the find string just did nothing. No output, no error, no nothing, just displayed my command prompt again. Since the reinstall akmod command reported success, I am assuming that maybe this also has something to do with BIOS/UEFi setup, but I could be, and probably am, wrong.

Thank you very much!!! Sorry it’s taking me a while, I have my main Linux distro which works and where I do most of my work, when I don’t need Windows. Anyway, I did run the commands after overcomming some DNS issues, and they finally worked and I installed b43-firmware, finally! Still no WiFi, but that maychange once I reboot. Keeping my fingers crossed!!

Sadly still no WiFI even after a reboot. Bummer. Why is it so complicated to set up WiFi in Fedora? Anyway, thank you very much for your help. I really had my hopes up there with new information (the Tainted part) and finally being able to install the b43 stuff but alas, still not showing any WiFi networks…

It’s a mixture of closed source drivers (if they were open source and in the kernel like all the other hardware out there, we wouldn’t have to do all this extra stuff) and/or secureboot (also a major issue because if this is enabled, one cannot load extra kernel modules and so on).

So, it’s unfortunately not an issue that Linux/Fedora created, but one that we need to deal with as users.

Questions:

  • was the kernel module built?
  • was it loaded, if built?
  • what’s the output of sudo lsmod?

B43 may be for newer hardware only; is your machine older or newer? (My Broadcom card is from 2016+)

Please don’t laugh, but mine is 2014 i believe. A Lenovo X140e.

Sorry, that was the output of lsmod, I wasn’t sure if it would let me post it. I am using Fedora 36, the latest edition and updated. Hopefully you’ll be able to tell something… And will this be a procedure everytime I upgrade Fedora? Or once we get it figured out I’ll be set?
