I upgraded to Fefora 22 since I am having the same problem that keep recurring. the networking keep getting broken.

when i would update with Yum I would not have a problem with getting rpmfusion to load the wl module and keep the wireless working. when I update with dnf the wl module does not get loaded. I have gotten the rpmfusion repositories to install. but I still have a problem that keep occurring. when I try to install the kmod-wl i get following error.

# dnf install kmod-wl
Last metadata expiration check performed 1:37:31 ago on Tue Jun 30 07:20:35 2015.
Error: package kmod-wl- requires kmod-wl-4.0.4-301.fc22.x86_64 >=, but none of the providers can be installed

So naturally i try the following install

# dnf install kmod-wl-4.0.4-301.fc22.x86_64
Last metadata expiration check performed 1:40:43 ago on Tue Jun 30 07:20:35 2015.
Error: package kmod-wl-4.0.4-301.fc22.x86_64- requires kernel-uname-r = 4.0.4-301.fc22.x86_64, but none of the providers can be installed

That is the problem the kernel in the latest update is 4.0.6-300.fc22.x86_64 which keeps me from loading the wl module and driver.

I have tried to use the Broadcom STA driver but I get errors with that also. I can not get passed the "make" command. here is the error I get.

kmod-wl and akmod-wl is the broadcom sta driver, fwiw.

This post is a wiki. Anyone with karma >750 is welcome to improve it.

The fix is very easy. I used the suggestion from the help of "aeperzt." Here is how you can get the Broadcom BCM4312 to work.

1) login as a root user or sudo which will ask for root password. Then as a root user you will be allow root permissions to enter commands to install. The "#" symbol is the command prompt for a root user.

Enter the following commands

# dnf update --best --allowerasing

This will install the correct kernel-devel package for the current kernel.

# akmods --force

Checking kmods exist for 4.0.6-300.fc22.x86_64 [ OK ] Building and installing wl-kmod [ OK ]

# modprobe wl

After this the WiFi light comes on and finds my network.

Thank everone for their help.

When I try this it says modprobe: ERROR: could not insert 'wl' : Unknown symbol in module, or unknown parameter (see dmesg) and dmesg says the module verification failed: signature and/or required key missing - tainting kernel I have also posted this as a seperate question here any ideas?

what I entered was the command line command at the root command prompt. akmods --force which gave me the following response. Checking kmods exist for 4.0.4-303.fc22.x86_64 [ OK ] Building and installing wl-kmod then I entered the following command at the root command prompt

modprobe wl everything worked. Did you have RPM fusion free and non-free repositories loaded. to load the repositories. use the following commands for the free repositories. wget dnf install rpmfusion-free-release-22.noarch.rpm

For the non-free RPM fusion use the following commands wget dnf install rpmfusion-nonfree-release-22.noarch.rpm you also have to have the kernel module 4.04.303.fc22x86_64 installed

Then do the commands akmods --force the after it finishes enter the command modprobe wl

Thankyou SOLVED. I uninstalled kmod-wl akmod-wl then reinstalled both followed your instructions (although it did not show Building and installing wl-kmod and the final touch for my Dell Inspiron 1545 was to hit ctrl + F2 and this activated manual wifi switch and wifi appeared :)

To avoid this you need to install akmod to know why an the difference look at
