CentOS 7 and Broadcom BCM4318 does not work
I have a HP Pavillion dv8000 laptop that I just installed CentOS 7 on. I am new to CentOS, but I've been using Ubuntu derivatives for about 4 years now. I got CentOS 7 installed nicely, and I love it. The only problem is that I can't get wifi to work. My laptop has a button just above the keyboard to turn wifi on and off, but pressing it does nothing. I first went into the BIOS and made sure that WLAN was enabled. I even disabled it and then reenabled it just to be sure. Then I ran "rfkill list all" and it came back that WLAN was neither hard blocked nor soft blocked. I have had this problem before in Ubuntu, and I installed b43-fwcutter to fix it, but I don't know how to do this in CentOS. I believe it was in the repos in Ubuntu.

Hopefully you saved the firmware files.

Code: Select all
An updated package, wl-kmod-6_30_223_248-2.el7.elrepo.nosrc.rpm, has been released to the testing repository. This new package corrects the location of the blacklist file and creates the relevant file to modprobe the modules at system boot time.
Testing and feedback will be appreciated, please.

Following further successful testing, this package has now been promoted to the main repository:
./elrepo/el7/SRPMS/wl-kmod-6_30_223_248-2.el7.elrepo.nosrc.rpm
Please note that the documentation has also been updated:
http://elrepo.org/tiki/wl-kmod [^]
Now closing as "resolved/fixed".
wl-kmod-6_30_223_248-2.el7.elrepo.nosrc.rpm
has worked for my wl.ko kernel module build -
Code: Select all
# uname -r

# lspci -nnv

The rpm package . . .
kmod-wl-6_30_223_248-2.el7.local.x86_64.rpm
was built without network connectivity in CentOS 7 KDE -
I had dual boot of centos with Fedora 19 KDE (wlan0 up using b43 driver)
to rpm package downloads of all needed dependencies via USB flash drive.
Just now posting from the CentOS 7 KDE with default Firefox browser.
