Best effort driver installation process

NOTE: Make sure that CentOS / RHEL is updated to the latest patches before attempting wireless driver installation.

Building the driver will require RPM Package Manager (RPM) to activate the Broadcom 802.11ac card in RHEL / CentOS 6.5.

NOTE: $USER = dell, $HOME = dell
  1. Open the terminal and become su (root):
    • $ su -
    • # yum update
    • Reboot
  2. Install the Kernel Development Packages
    • Open the terminal and become su (root):
    • # yum groupinstall "Development Tools"
    • # yum install redhat-lsb
    • # yum install kernel-devel
  3. Drop to normal user (type exit)
    • $ mkdir -p ~/rpmbuild/{BUILD,RPMS,SPECS,SOURCES,SRPMS}
    • $ echo -e "%_topdir $(echo $HOME/rpmbuild)\n%dist.el$(lsb_release -s -r|cut -d"." -f1).local" >> ~/.rpmmacros
  4. Download the Closed Source RPM for the 802.11ac card:http://elrepo.org/linux/elrepo/el6/SRPMS/wl-kmod-6_30_223_141-2.el6.elrepo.nosrc.rpm
    • $ cd ~/Downloads
    • $ wget
  5. Download the Broadcom Driver Source for RHEL / CentOS 6.5
  6. Copy the Broadcom Driver Source to the SOURCES directory under rpmbuild:
    • $ cp ~/Downloads/hybrid-v35_64-nodebug-pcoem-6_30_223_141.tar.gz ~/rpmbuild/SOURCES
  7. Copy the Closed Source RPM to the rpmbuild directory:
    • $ cp ~/Downloads/wl-kmod-6_30_223_141-2.el6.elrepo.nosrc.rpm ~/rpmbuild
  8. Change to the rpmbuild directory
    • $ cd ~/rpmbuild
  9. Start the process to rebuild the RPM to work with the current Kernel (2.6.32-431.11.2.el6.x86_64)
    • $ rpmbuild --rebuild --define 'packager <$USER>' wl-kmod*.nosrc.rpm
  10. Become root again
    • $ su -
  11. Install the customized RPM for the 802.11ac card, replace /dell/ with the users home directory name
    • # rpm -Uvh /home/dell/rpmbuild/RPMS/x86_64/kmod-wl*.rpm
  12. Activate required wireless modules:
    • # modprobe -r b43 b43legacy ssb wl lib80211
    • # modprobe -r bcma
    • # modprobe lib80211_crypt_tkip
