CentOS - Dec 2018 - Centos7- WiFi not recognized - HWaddress - Or Any Idea

Hello,
I recently installed centos7+Gnome on my macbook air , at first start the
wireless adaptor , which is the (infamous?) BCMA4360 , seemed to work because I
was asked to choose the network and provided password, but thereafter wifi did
not appear, so I can connect to the Internet only by cable. Googling a few days
and checking on my computer I found the following:- the infamous wifi adapter
BCM4360 appears on lshw list- the driver for wifi adapter appears on lsmod list
as BCMA, and I also find the driver, bcm-pci-bridge in sys/bus/drivers- i
didn't find any file in /etc/sysconfig/network_scripts where the device is
bcma wifi adapter, or any wifi.
My idea to workaround this is: to create a file in
/etc/sysconfig/network_scripts/, in wich i inteded to pass the HWadress of the
device(BCMA4360), but I wasn't able to find a way to get this address.If
somebody can help me to find a way to get this HWaddr would be very
appreciated.Or any ideas to get wifi on my fancy macbook air with centos and no
macos at all, because at installation somehow i accomplished the performance to
format the entire disk.I also mention that I am not an IT guy, but I want to
learn a lot about the linux centos, but first things first : I need wifi.
Regards,
Cristian

Hi Cristian,

Some time ago I installed CentOS 7 on a client's MacBook Pro, with a
Broadcom wireless card.

Here's my notes (in french) :

First make sure to upgrade the kernel to ELRepo's kernel-lts

Once you have that, install the driver as described in the article.

Cheers,

Niki

On my system "lshw -C network" reports my unconfigured
wifi interface.  The mac address is reported as a
"serial number".
