Hi guys!

So I'm using Fedora 28 and since then I've been having problems with my wireless device because I have a Dell laptop. It turns out that I installed RPMFusion and all the drivers for my Broadcom BCM4312 device, but when I ask for the device to read, the right thing was to be configured to use the "wl" driver, but note that when I play the "lspci -v "it returns me that my device is using the" b43-pci-bridge "drive and for it to work it needs to be in" wl ". How can I proceed in relation to this? Thank you in advance for your attention. Below I will paste the command reading "lspci -v".

I have a Dell Vostro 1320. These commands worked for me:

dnf remove b43-openfwwf.noarch
sudo dnf -y install broadcom-wl-dkms

Output after commands execution:

$sudo lspci -v

I have a Dell Inspiron 14 and Broadcom BCM4312 working fine; but the drivers comes from UnitedRPMs; First; I suggest you to delete the drivers from Rpmfusion...

Enable the repository

HERE

Now Install the driver...

dnf -y install broadcom-wl-dkms

Here are some notes I took when doing a similar thing some years ago. As the post says, YMMV.
