wifi Driver in Centos

i have installed CentOS 6.5 64 Bit OS in my Dell 1535 Laptop, my wifi device is not working, i have downloaded broadcom 64 bit driver for linux, i have installed "kernel-devel", "kernel-headers" & group of "DEVELOPMENT TOOLS", i have extracted that driver, & when i am running make command i am getting this error :

make[2]: *** [/usr/local/src/hybrid-wl/src/wl/sys/wl_cfg80211.o] Error 1
make[1]: *** [_module_/usr/local/src/hybrid-wl] Error 2
make[1]: Leaving directory `/usr/src/kernels/2.6.32-431.23.3.el6.x86_64'
make: *** [all] Error 2

This indicates compile error. Try installing wl-kmod from the EL Repository instead of compiling from source.

yum update kernel
yum install wl-kmod

Open in new window

ASKER

i have EL Repository, i have updated kernel, but there is no such package wl-kmod

Can you try the rpmfusion repository?

ASKER

i did

Can you provide the out of the following?

yum repolist

Open in new window

I see the same issue in my lab, wl-kmod no longer compatibile after 6.3.

Try kmod-compat-wireless. (Unfortunately I do have a broadcom chip to test with)

ASKER

this package is also not available, what to do now???

You need this repo for wl-kmod:
http://elrepo.org/tiki/tiki-index.php

ASKER

i got this package "kmod-r8168" from this repo, not "wl-kmod" package, how can i get this package.

You need to build RPM - elrepo provides just sources to do so
http://elrepo.org/tiki/wl-kmod
Can you show output of "lspci -n" so experts can check if no other (opensource) driver can be used?

Your card (14e4:4315) is supported by b43 driver. No need to build anything.
http://wireless.kernel.org/en/users/Drivers/b43
I think kernel-firmware package has missing bits to make it work.

ASKER

this package is already installed, my wifi still not working, help please

Letch check status of b43 driver:

dmesg | grep b43
ifconfig -a
ifconfig wlan0 up

In this output the "wlan0" is my usb wifi device, not my laptop integrated wifi

# yum install b43-openfwwf

Then
# ifconfig wlan0 down ; ifconfig wlan0 up
to trigger firmware load

(or reboot)

ASKER

this package is also already installed.

rpm -ql b43-openfwwf

i see 5 files and none is amon those wanted by driver.

So you need to extract firmware from wl driver archive.
Follow the link http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware from dmesg.
Get wl_apsta from 478.104 for firmware for card hardware v15 and install b43-fwcutter
Once you run later with -l you see supported versions and with --help you get command to extract driver to right place.

ASKER

b43-openfwwf package is already installed, what you want me to do with package ?

That package is installed with minimum system, just that is unused like 30 other firmware packages.
You need to :cut: the firmware from proprietary driver to make your card work. Probably over time your card will get open firmware, but as of now it is not like that.

ASKER

can u please tell me, how can i do that ?

follow the link. Download correct driver version extract file from tarball. run command from help tet of b43-fwcutter

ASKER

i am not getting it

Click this link:
http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware
run
b43-fwcutter -l
fw15 ... 478.104
If you are using the b43 driver from older kernel:
(follow instructions there)

The driver file is linked here:
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx (search for precise pangolin for download link)

ASKER

totally confusing, i m not getting this at all.

Which is a no-go:
* Download proprietary driver
* extract tarball
* install fwcutter
* extract firmware from files extracted from tarball

???

Sounds more like a workaround :)

One can install linux in virtualbox or vmware player in windows and do their Linux experiments.

i have installed windows
