BCM43228 não funciona desde o kernel 3.15.xx

Question

Como yum update , meu Wi-Fi está desconectado. O comando rfkill list retorna:

0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no

Eu vi que eu tenho que rmmod hp-wmi e eu fiz isso e o Soft (visto na saída acima) não foi bloqueado depois disso, mas o problema continua.

Eu preciso fazer ifconfig wlo1 up . Seja o que for que não funcione.

o comando dmesg | grep wl retorna:

Idéia # 1

Eu começaria tentando obter os drivers mais recentes da Broadcom, que estão disponíveis aqui:

• link

Idéia # 2

Talvez este post seja o seu problema? Intitulado: Broadcom Wireless não funciona no kernel do Fedora 20 3.15 . Ele detalha 2 bugs detalhados aqui:

• link
• link

Junto com um patch detalhado no rastreador de bugs do Gentoo:

$ curl https://513156.bugs.gentoo.org/attachment.cgi?id=378836 -o patch.txt 

As outras etapas desta postagem do blog são as seguintes:

trecho

I took a chance and applied this directly to the code in /tmp/wifi. The patch succeeded and the module compiled.

$ sudo yum install patch
$ cd /tmp/wifi && patch -p1 < patch.txt 

Next I needed to copy the module to the default modules folder searched by modprobe.

$ sudo mkdir /lib/modules/'uname -r'/extra/net/wireless
$ sudo cp wl.ko /lib/modules/'uname -r'/extra/net/wireless
$ sudo depmod -a 

Next remove any other sofware and drivers that might conflict with this one. In my case this meant removing the Broadcom OpenFWWF package and removing and blacklisting the bcma kernel module.

$ sudo rmmod bcma
$ sudo echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
$ sudo yum remove b43-openfwwf.noarch

To install the new module using modprobe

$ sudo modprobe wl

To load the module on boot I simply ran

$ sudo echo modprobe wl >> /etc/rc.local  

Finally use NetworkManager to configure the new device.Oh and thanks to my ex-colleague Steve for the laptop ;-)
