Today I want to share some good news for those users having a BROADCOM WLAN adapter in their machines ... until now we had to build the drivers manually by building the kmod-wl module ourselves. This is not longer necessary, because RPM Fusion now provides an akmod-wl drivers module for RHEL. All we have to do is add/enable some repositories and install the drivers. A big improvement (as a side effect) is, that the drivers don't have to be reinstalled after each major kernel upgrade. Thanks to the RPM Fusion maintainers for providing this convenient solution.
