My system (Fedora 20) recently installed a kernel update (3.15.8). When I use this kernel, my wireless (BCM 43228) is not working anymore. Broadcom-wl driver is already installed and the latest version. Everything still works perfectly in 3.15.7. I cannot find any information about this so I post it as a new question.

Is this a bug, do I need a new driver, or is there another solution?

If I need to supply any more information, please say so.

Please provide the output of the following command: rpm -qa "*kmod*wl*" I guess that you don't have the matching kmod-wl package installed. Your problem will probably will be solved by updating kmod-wl package, or by installing akmod-wl package if the kmod-wl package is not in the repositories yet.

Try modprobe wl and post results. Offtopic: what is the difference between a/kmod-wl?

@hello kmods are compiled modules for a specific kernel version. For each kernel version, a specific kmod* package version is needed. However, akmods contain source code for the module, and is called during boot. It checks if the module is compiled for the running kernel, if not, it'll compile the source code of the module for the running kernel and install and load it.

(In fact, akmod creates and installs a kmod package locally each time it sees a new running kernel). If you install akmod-wl, you can safely upgrade kernels unless the module source code fails to build for the new one.
