Wireless problem with new kernel


Hi,

I have problem with wireless with the new kernel "2.6.34.6-47.fc13.i686.PAE". However when I boot into the old kernel I don't have problem using wireless.
Can someone help me with this. I have the broadcom-wl installed and somehow it seems like it doesn't support the wireless for the new kernel.

Thanks

do a lspci -v and see if any other drivers are trying to hog your card from the new kernel. if you don't understand, then just post the outut of that command.

It is a common problem across all distros with the newer kernels, you have to update the broadcom driver as well. I do not know about fedora but for Debian/Ubuntu the only solution for the moment (as of last week anyway) is to compile and install the new driver from source. I just went back to the older kernel as there is nothing I need in the new kernels anyway.

Look for an updated Fedora broadcom package.

Thanks for the help. I received an update for the kmod-wl for the new kernel and the wireless started working.

I have a question. What is the difference between kernel and kernel-PAE ?
Do I need both the kernels or just one of them is sufficient to boot

Same problem

I am having the same problem this morning after upgrading the kernel to 2.6.34.6-47. Where did you get the updated kmod-wl? When I try "yum update kmod-wl" it tells me I have the most up to date version. The version I have is kmod-wl-5.60.48.36-1.fc13.13.x86_64.

Thanks.

Run su -c "yum update" and then go to System->Preferences->Software Updates and try to update. I tried this way and I got the kmod-wl update for my laptop.
What is your wireless device ?

kernel-PAE is used for msinly a 32 bit system with more than 4GB of RAM, as far as many other things that wouldn't be compatible systems. PAE stands for physcial address extension, more can be read about it below.
