After yum update and upgrading my kernel. My wifi is not working any more. After trying to install kmod-wl from rpmfusion-nonfree for my kernel I get transaction check error's and kmod-wl is not getting installed. Is there a solution or do i really have to downgrade my kernel?

There are two potential causes of this that I know about. Check them out and see if any apply:

  1. You might have another, incompatible software repository installed. If you've been provided with your current kernel from somewhere else, you might find that the one you're trying to install the current kmod-wl module for is incompatible. If this is the case, then removing the offending kernel and rebooting is probably the most sensible approach.

  2. It could be that the official repositories have just provided a new kernel and that rpmfusion haven't rebuilt their kmod packages yet. If this is the problem then you should just give it a day or two and try again. If it's not fixed in a few days, then ask the rpmfusion people about it. Sometimes (extremely rare) a kmod package gets missed from their build lists and you have to give them a nudge. I've done that twice in ten years of Fedora over the nVidia drivers.

You could, of course, download the source package. I believe rpmfusion also provide an auto-build package which provides the source code and will rebuilt the module on bootup to match your kernel (the certainly have this for the video drivers). This is much less convenient but it can work around such problems.

Thanks Cobra. I was triggerd with you're option 1 answer. I did a backup of all my data and re-installed from fresh. Then updated to the latest kernel and installed kmod-wl. Now my wireless is working again :-)

To prevent youself from being hit by @cobra's issue No. 2, install the packages akmods and akmod-wl from rpmfusion. akmods automatically build the relevant kernel modules for a new kernel.
