Hello
your question answered mine, one of the reasons I'll wait a while to install CentOS 8
I have BCM 4313, using the rpmfusion wl packages.
The RPMFusion el8 repo doesn't contain the broadcom akmod/kmod wl rpms yet, but you could try installing the el7 rpms from here https://download1.rpmfusion.org/nonfree ... index.html you'll need the broadcom-wl, akmod-wl and (current/running/uname -r) kernel-devel packages, they work with the latest elrepo mainline kernel (currently 5.3.2-1.el7.elrepo.x86_64) so I can't see the kernel version being a problem.
The broadcom-wl and akmod-wl rpms will need to be installed together then a reboot.
I know it's never a great idea to install rpms from different releases, but this sounds like you have a fresh install with no working wireless, so why not be the test pilot ;)
Hopefully rpmfusion will have el8 rpms soon.
Let us know if you have success.

Hello. I am new to Centos. Since i am faced with the same problem, i was wondering if someone would point me to a proper set of instructions on resolving this. It appears that the "repo" mentioned, now has packages for version 8, but i need further guidance if available.

Re: Centos 8 and broadcom ? - SOLVED (for me)

Post by oceanjeremy » 2020/06/06 13:51:08

I just installed CentOS 8 on a MacBook Pro and it wasn't recognizing my Wi-Fi or my ethernet controller. No internet at all. This got me connected in about fifteen minutes.

I got my instructions from these two pages:
- https://centos.pkgs.org/8/rpmfusion-non ... h.rpm.html
- https://centos.pkgs.org/8/rpmfusion-non ... 4.rpm.html

This is what worked for me:
  1. Get on a different machine (one that connects to the internet), so I can put the Wi-Fi driver on a USB drive and take it to my new CentOS machine
  2. Download Broadcom driver common files: https://download1.rpmfusion.org/nonfree ... noarch.rpm
  3. Download wl kernel modules: https://download1.rpmfusion.org/nonfre ... x86_64.rpm
  4. Take those (via USB drive) over to my new CentOS machine and drop into terminal (as root user)
  5. Run this command:

    Code: Select all

    # rpm -Uvh broadcom-wl-6.30.223.271-13.el8.noarch.rpm kmod-wl-4.18.0-147.el8.x86_64-6.30.223.271-32.el8.x86_64.rpm
    # dnf install kmod-wl-4.18.0-147.el8.x86_64 broadcom-wl
  6. Reboot CentOS 8 machine
To be completely honest I did this last night while a little bit tipsy and I can't remember each step exactly. I think you might need to double check your kernel (# uname -r) and make sure it matches? Not sure, I'm a Linux beginner myself.

But hopefully this can get you up and running!

@mrsr2174:

You have to install all of the dependent packages at the same time, in one command. (Just rpm -Uvh pkg1.rpm pkg2.rpm pkg3.rpm etc)

However... these drivers worked for the last CentOS 8.1 kernel. I haven't had any luck finding a driver that works for CentOS 8.2 kernel, which you are probably running now.

I'm trying to work around the whole issue by getting a USB WiFi card. Eventually if I still want to use this MacBook I might replace the internal WiFi card with one that CentOS plays nicely with, but I'm not there yet.

Best of luck, let me know if you find a solution.

I tried below & sucessfully install broadcom-wl & kmwod-wl.

rpm -Uhv rpmfusion-free-release-8-0.1.noarch.rpm
rpm -Uhv rpmfusion-nonfree-release-8-0.1.noarch.rpm
rpm -Uhv rpmfusion-nonfree-appstream-data-8-1.el8.noarch.rpm
rpm -Uhv rpmfusion-nonfree-release-tainted-8-0.1.noarch.rpm
dnf install broadcom-wl

ifconfig -a , show a new device , when i tried to connect it is not connecting

wlp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
ether 60:d8:19:2b:58:0f txqueuelen 1000 (Ethernet)

rpm -Uhv rpmfusion-nonfree-release-8-0.1.noarch.rpm
rpm -Uhv rpmfusion-nonfree-appstream-data-8-1.el8.noarch.rpm

Thank you so kindly for this! Ever since CentOS upgraded to 8.2 my wifi hasn't worked, and it's because I installed the broadcom-wl driver manually. So it still was using the kmod-wl for 8.1 (kmod-wl-4.18.0-147.el8).

I had the first three packages, but did not have rpmfusion-nonfree-release-tainted. I installed that one and it still would say dependencies resolved / nothing to do when I tried to install broadcom-wl, so I just dnf removed it then dnf installed it again right after. I watched it pull down the correct kmod whitelist (kmod-wl-4.18.0-193.6.3.el8_2x86_64).

I rebooted, et voilà! My internal wifi card was working again.

Thanks so much mrsr2174!!
