In this howto i will describe quick fix for Access Points not shown in Fedora 13 even you install Broadcom wireless driver using rpmfusion.org. For those who doesn’t know how to install broadcom driver for wireless card, you need to do following steps to install broadcom driver for wireless card.

1) Install RPMFusion Repositories

rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

2) Install Broadcom Wireless Card Driver

yum install broadcom-wl kmod-wl

reboot the system to get modules get loaded. But when you try to scan using NetworkManager or wlaassistant, it show’s no wireless access point found. Even they are visible on computer desk available next to you.

3) Fixing Access Points not showing.

Its a quick and dirty fix from fedora forums.

vi /boot/grub/grub.conf

edit your available kernel lines and append intel_iommu=off in the end for kernel parameters.

kernel /vmlinuz-2.6.33.5-112.fc13.x86_64 ro root=/dev/mapper/vg_server1-LogVol01 rd_LVM_LV=vg_server1/LogVol01 rd_LVM_LV=vg_server1/LogVol00 rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet

change to

kernel /vmlinuz-2.6.33.5-112.fc13.x86_64 ro root=/dev/mapper/vg_server1-LogVol01 rd_LVM_LV=vg_server1/LogVol01 rd_LVM_LV=vg_server1/LogVol00 rd_NO_LUKS rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYTABLE=us rhgb quiet intel_iommu=off

save the file and reboot the system again to get kernel to load following kernel parameter and bravo you can see the Access Points 🙂
