I’ve upgraded my system from fedora 36 to 38, and all works great except for the wifi driver, so in this entry I’m goig to show how to fix it.
May be you want to read my previous post to get some useful tips.
Ok, let’s get started:
1. Getting some details about your device, in my case is a BCM4331:
[jaehoo@macbookpro-jaehoo broadcom-wl]$ lspci | grep -i broadcom 02:00.0 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM57765 Gigabit Ethernet PCIe (rev 10) 02:00.1 SD Host controller: Broadcom Inc. and subsidiaries BCM57765/57785 SDXC/MMC Card Reader (rev 10) 03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4331 802.11a/b/g/n (rev 02)
2. Install the next packages:
# install kernel to build modules
sudo dnf install dkms kernel-devel-`uname -r`
#Install broadcom pakage dependencies
sudo dnf install broadcom-wl kmod-wl
3. Download a copy of the driver from this github repository: https://github.com/antoineco/broadcom-wl and uncompress the zip file
4. Open a terminal, build and install the driver:
[jaehoo@macbookpro-jaehoo broadcom-wl]$ make KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd` make[1]: se entra en el directorio '/usr/src/kernels/6.2.15-300.fc38.x86_64' warning: the compiler differs from the one used to build the kernel The kernel was built by: gcc (GCC) 13.1.1 20230426 (Red Hat 13.1.1-1) You are using: gcc (GCC) 13.1.1 20230511 (Red Hat 13.1.1-2) CFG80211 API is prefered for this kernel version Using CFG80211 API CFG80211 API is prefered for this kernel version Using CFG80211 API make[1]: se sale del directorio '/usr/src/kernels/6.2.15-300.fc38.x86_64' [jaehoo@macbookpro-jaehoo broadcom-wl]$ sudo make install install -D -m 755 wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
5. Load module to test it:
[jaehoo@macbookpro-jaehoo broadcom-wl]$ sudo depmod -A
[jaehoo@macbookpro-jaehoo broadcom-wl]$ sudo modprobe wl
[jaehoo@macbookpro-jaehoo broadcom-wl]$ sudo akmods
Checking kmods exist for 6.2.15-300.fc38.x86_64 [ OK ]
[jaehoo@macbookpro-jaehoo broadcom-wl]$ lsmod | grep wl
wl 6541312 0
cfg80211 1269760 1 wl
[jaehoo@macbookpro-jaehoo broadcom-wl]$ nmcli dev wifi list

As you can see the nearest networks are detected.
6. Reboot the system, now the wireless networks must appear into the network manager.
7. In order to avoid rebuild the driver manually on every new kernel installation, you can add the module to be builded by the operating system automaticly:
sudo dkms add /path/to/this/repo
sudo dkms status
