Install the wireless card driver manually under Linux

Install GCC with " local Yum source installation gcc " first.

HP laptop installed CentOS6.3, did not install the wireless card driver, install the driver, Google found a lot of information, finally solved the problem. Make some records here and hope to help others.

My machine is 32 bits, CentOS kernel version is 2.6.32-279.19.1.el6.i686, download the wireless card driver is hybrid-portsrc_x86_32-v5_100_82_112.tar.gz

Here are the specific steps

One: Determine the model of the wireless network card, driver download

The first step is to determine the wireless network card model is what, you can use the command

[email protected] ~]$/SBIN/LSPCI | grep Broadcom
02:00.0 Network controller:broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (Rev. 01)
Or
[[Email protected] ~] $LSPCI | grep Wireless

The corresponding driver is visible: Broadcom BCM4313

Download driver: http://www.broadcom.com/support/802.11/linux_sta.php

Where there is a README.txt file on the download page, there is a paragraph in this description:

Supported DEVICES
—————–
The cards with the following PCI Device IDs is supported with this driver.
Both Broadcom and and Dell product names are described. Cards not listed
Here is also work.

To find the Device ID ' s of Broadcom cards in your machines do:
# Lspci-n | grep 14e4

Run:
[[Email protected]ntos ~]$ lspci-n | grep 14e4

CentOS Kernel Source code is placed in the/usr/src/kernels directory; If the kernel is upgraded online, it is also placed in this directory; If there is no content in the/usr/src/kernels/in your system, the source code package Kernel-devel software package that does not have the kernel installed; Through the online installation of the kernel source package, can be installed through Yum, the kernel source will be placed in the directory under the/usr/src/kernel

[email protected] ~]# yum install kernel-headers kernel-devel gcc

If the kernel source package is not installed, an error will be reported in the following make:

[Email protected] hybird-wl]$ make-c/lib/modules/' uname-r '/build/m= ' pwd '
Make: * * */lib/modules/2.6.32-279.el6.i686/build/: No such file or directory. Stop.

Second: Set up the installation directory

[Email protected] ~]# mkdir-p/USR/LOCAL/SRC/HYBRID-WL
[Email protected] hybrid-wl]# CD/USR/LOCAL/SRC/HYBRID-WL
[Email protected] hybrid-wl]# tar xvfz/path/to/the/tarball/hybrid-portsrc_x86_32-v5_100_82_112.tar.gz (name of the Downloaded file)
[Email protected] hybrid-wl]# chown-r SOMEUSER.SOMEGROUP/USR/LOCAL/SRC/HYBRID-WL

Three: Compiling

[[email protected] hybird-wl]$ make

The first compile, reported the following error:

Kbuild_nopedantic=1 make-c/lib/modules/' uname-r '/build m= ' pwd '
MAKE[1]: Entering directory '/usr/src/kernels/2.6.32-279.el6.i686′

Google a bit, found that the CentOS6.3 version of this newspaper is the same error, find a lot of information there is no good solution. Looking back at Broadcom's REAMME.txt, the inside wrote a passage:

If your driver does not build, check to make sure you have installed the
Kernel package described in the requirements above.

This driver now supports the new Linux cfg80211 wireless configuration API in
addition to the older Wireless Extensions (wext). The makefile would
automaticly build the right version for your system but it can be
Overridden if needed:

# Make Api=wext
Or
# Make api=cfg80211

Try to recompile

[[email protected] hybird-wl]$ make clean
[email protected] hybird-wl]$ make Api=wext

The compilation passed, generated the Wl.ko this file, found that still have to look at the official documents. Install after you finish compiling

[[email protected] hybird-wl]$ make install

The installation is to copy the files to the/lib/modules/<kernel-version>/kernel/net/wireless directory.

Four: Drive Configuration

Remove all other Broadcom wireless device drivers. In addition to the drivers we have compiled, the other Broadcom 802.11 chips drive like b43, BCMA and SSB. This drive is in conflict with our new drive. So we have to remove them first.

# Lsmod | grep "B43\|SSB\|BCMA\|WL"

If any of the following drivers exist, remove it:

[[email protected] HYBIRD-WL] $rmmod b43
[[email protected] HYBIRD-WL] $rmmod SSB
[[email protected] HYBIRD-WL] $rmmod BCMA
[[email protected] HYBIRD-WL] $rmmod WL

These configurations are blacklisted to keep them from being used:

[[email protected] hybird-wl] $echo "blacklist SSB" >>/etc/modprobe.d/blacklist.conf
[[email protected] hybird-wl] $echo "blacklist bcma" >>/etc/modprobe.d/blacklist.conf
[[email protected] hybird-wl] $echo "blacklist b43″>>/etc/modprobe.d/blacklist.conf

Load a new drive

[[email protected] HYBIRD-WL] $modprobe lib80211 # because Wl.ko need to rely on the module
[[email protected] HYBIRD-WL] $insmod Wl.ko

Now your network management program should be able to find the device, you can use the wireless network! Finally add boot boot

[[email protected] wireles_smoudules]# cp wl.ko/lib/modules/' uname-r '/kernel/drivers/net/wireless
[Email protected] wireles_smoudules]# depmod-a
[Email protected] wireles_smoudules]# echo modeprobe WL >>/etc/rc.local
