Macbook Air wireless broadcom BCM4360 not functioning

[able_flosser]

Hi,

It seems that my wireless does not work, there are several conflicting solutions online some of which i used. but with no success my output is as such:
lspci -nn | grep -i net
03:00.0 Network controller [0280]: Broadcom Limited BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)
0a:00.0 Ethernet controller [0200]: Broadcom Limited NetXtreme BCM57762 Gigabit Ethernet PCIe [14e4:1682]
$

could some help explain what the best method is for solving this?

thanks!

Code: Select all

$ grep -i 14e4 /lib/modules/3.10.0-514.26.2.el7.x86_64/modules.* | grep -i 43a0
/lib/modules/3.10.0-514.26.2.el7.x86_64/modules.alias:alias pci:v000014E4d000043A0sv*sd*bc*sc*i* bcma

Says it's supported by the bcma module. What happens if you modprobe that and then look at the output from dmesg to see what it says? Also, is NetworkManager-wifi installed?

HI TrevorH,

to start with your last question first yes,Networkmanager-wifi is already installed. i assume it doesn't need to be mounted, but just guessing.

As for your the ' modprobe' i am new to linux, learning a lot but i don't know how to do this:
'What happens if you modprobe that and then look at the output from dmesg to see what it says'

could you break it down for me? sorry i am a noob...

best,

[TrevorH]

So the grep I ran says that your wireless card pci vendor/device id is supported by the bcma module. As root if you run lsmod | grep bcma it should show as loaded if it is. If not then as root again run modprobe bcma to load it and then run dmesg | less and page to the end to see if it said anything useful when it loaded.

Hi TrevorH,

here the response

$ lsmod | grep bcma
bcma 52492 0


$ modprobe bcma
$


$dmesg | less

what am i looking for?

[TrevorH]

Since it was already loaded, I'd suspect you already have an interface for it. What does ifconfig -a say?

[able_flosser]

it does seem strange, the middle one is lacking a IP adress, not sure if that is the cause of my non-wireless predicament..

$ifconfig -a

[TrevorH]

None of those are your wireless network card. I know that broadcom cards often need special action but I've always avoided them so don't know what.

[able_flosser]

hmmm, that puts me in a pickle...do you have any suggestion on where i should look?
