broadcom-wl not working since 2.6.40.6-0.fc15.x86_64 kernel update

Since the Kernel update last week, I no longer see the "wireless" option in the Network Manager dropdown menu.

This seems to be a question that has been asked in the past on these forums but at the same time, Im not 100% sure of the real issue and solution. My thoughts are that the kmod-wl is not at the same version as the lastest kernel update ?


Looking at my current setup, I can see the wl module is no longer found.

Code:
$ modprobe wl
FATAL: Module wl not found.

Code:
$ lsmod

Re: broadcom-wl not working since 2.6.40.6-0.fc15.x86_64 kernel update

You have to update the kmod-wl package to match your kernel version.

your kernel is version 2.6.40.6-0 and the kmod you have installed is for 2.6.40.4-5

the kernel module MUST match the kernel version.

You can either wait for an updated kmod-wl to be put into the rpmfusion repo, or you can install the akmod package, then it will build the kernel module for you when you update your kernel.

Re: broadcom-wl not working since 2.6.40.6-0.fc15.x86_64 kernel update

Thanks very much for your reply.

Is there any reason why the kmod-wl has not been available at the same time as the new kernel update ?

It doesn't seem right to release a new kernel which will then break a lot of computers ?!

Re: broadcom-wl not working since 2.6.40.6-0.fc15.x86_64 kernel update

well, the kernel is released in the fedora repos.

rpmfusion is where the kmod is located, and they are not controlled by fedora.

Usually, rpmfusion gets the kmod into the repo within a day or so but sometimes they lag behind. That's why installing the akmod is usually a better option. That way if the kmod isn't in the repo when you update your kernel, the akmod will build the module for you.

Re: broadcom-wl not working since 2.6.40.6-0.fc15.x86_64 kernel update

Can the kmod-wl and akmod-wl co-exist together? Or do I have to do a

Code:
su -c 'yum remove kmod-wl'
From what Ive read if I use the akmod-wl, is it just a case of running the following commands ?

Code:
su -c 'yum install akmod-wl'

su -c 'akmods --akmod wl'

Re: broadcom-wl not working since 2.6.40.6-0.fc15.x86_64 kernel update

They can exist together, but the akmods has been broken for a while now. Do a forum search to find related info on that topic. Alternatively, wait to install the new kernel until the kmod is available, usually only a day or two.

Re: broadcom-wl not working since 2.6.40.6-0.fc15.x86_64 kernel update

not running 64 bit f15 but the following post resolved the issue for me



basically
Install the broadcom-wl packages:
su -c 'yum install akmod-wl'
Build the kmod: su -c 'akmods --akmod wl'

You now have the driver build and installed. Try loading it:
su -c 'modprobe wl'

worked for me - * i had to remove my previous installs first.

I uninstalled the kmod-wl package, then installed and built the akmod-wl.

I now have wireless back working !!! )))))

Thanks all.
