我的笔记本是acer的，装上fedora16 后发现无线不能用。幸好有线能用，就在网上查相关资料说是可以通过 “ndiswrapper”模拟运行windows下的驱动，但是试了几次没有成功，可能是驱动对不上号吧。然后在windows下用驱动精灵查看无线网卡型号为Broadcom Corporation，于是乎就去官网查找这个驱动了。
网址为：http://www.broadcom.com/support/802.11/linux_sta.php
下面是我解决的过程：
首先，通过上面网址下载驱动，驱动分为64位版的跟32位的。里面有三个文件可供下载“32-bit driver”、“32-bit driver”、“README.txt”，千万别小看这个README.txt。这是官方给的说明文档，几乎所有问题人家都总结了，相当权威！本人装的是32位的linux。就以32的驱动为例了。
1、以root用户登录，或者su到root下也行。解压下载的驱动文件，例如：解压到/usr/soft/driver/hybrid-portsrc_x86_32-v5_100_82_112在终端下进入该目录，cd /usr/soft/driver/hybrid-portsrc_x86_32-v5_100_82_112
2、你会看到有个Makefile文件，我看到这个会很兴奋，就仿佛看到了终点站。终端下输入命令：make
3、完成后安装：make install，之后你会发现该文件夹下多了个 wl.ko的文件。这个就是无线网卡的驱动模块。
4、然后是卸载linux可能安装的无效驱动，因为无效驱动可能会让你的驱动失效
# lsmod | grep "b43\|ssb\|bcma\|wl"
If any of these are installed, remove them:
# rmmod b43
# rmmod ssb
# rmmod bcma
# rmmod wl
To blacklist these drivers and prevent them from loading in the future:
# echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
5、加载驱动程序--这步至关重要！
# modprobe lib80211 （我用的这个）
or
# modprobe ieee80211_crypt_tkip
然后加载刚才编的驱动，
# insmod wl.ko
停几秒钟，我竟然发现我的wifi指示灯居然亮了-说明我的驱动装成功了
6、通过“网络链接”，在无线中添加一个链接，ipv4设为DHCP就是自动获取（一般是默认的，不用修改），这时不出意外，你的网卡会自动搜索了，找到你的无线路由器就可以无线上网了。
7、重启你会发现的无线指示灯又不亮了，所以你要提前设好“开机启动”该驱动
#cp wl.ko /lib/modules/3.1.0-7.fc16.i686.PAE/kernel/drivers/net/wireless/
# depmod -a
# echo modeprobe wl >> /etc/rc.local (Fedora/SUSE)
至此已全部搞定，其实我也是部分翻译文档。我的fedora16成功链接我的无线路由器，这篇文章就是在wifi下发出的……嘿嘿

Broadcom Linux hybrid wireless driver
Version 5.100.82.1XX
DISCLAIMER
----------
This is an Official Release of Broadcom's hybrid Linux driver for use with
Broadcom based hardware.
WHERE TO GET THE RELEASE
------------------------
http://www.broadcom.com/support/802.11/linux_sta.php
IMPORTANT NOTE AND DISCUSSION OF HYBRID DRIVER
----------------------------------------------
There are separate tarballs for 32 bit and 64 bit x86 CPU architectures.
Make sure you use the appropriate tarball for your machine.
Other than 32 vs 64 bit, the hybrid binary is agnostic to the specific
versions (2.6.X) and distributions (Fedora, Ubuntu, SuSE, etc). It performs
all interactions with the OS through OS specific files (wl_linux.c, wl_iw.c,
osl_linux.c) that are shipped in source form. You compile this source on
your system and link with a precompiled binary file (wlc_hybrid.o_shipped)
which contains the rest of the driver.
PRECOMPILED DRIVER
-------------------
Some distros (Ubuntu and Fedora at the least) already have a version of
this driver in their repositories precompiled, tested and ready to go.
You just use the package manager to install the proper package. If
its available for your distro, this is usually an easier solution. See
the end of this document for further discussion.
ABOUT THIS RELEASE
-------------------
This is a rollup release. It includes and deprecates all previous releases
and patches. At the time of release there are no existing patches for this
release from Broadcom.
SUPPORTED DEVICES
-----------------
The cards with the following PCI Device IDs are supported with this driver.
Both Broadcom and and Dell product names are described. Cards not listed
here may also work.

NOTABLE CHANGES
---------------
Added Cfg80211 support (described below)
Added Monitor mode (described below)
REQUIREMENTS
------------
Building this driver requires that your machine have the proper tools,
packages, header files and libraries to build a standard a kernel module.
This usually is done by installing the kernel developer or kernel source
package and varies from distro to distro. Consult the documentation for
your specific OS.
If you cannot successfully build a module that comes with your distro's
kernel developer or kernel source package, you will not be able to build
this module either.
If you try to build this module but get an error message that looks like
this:
make: *** /lib/modules/"release"/build: No such file or directory. Stop.
Then you do not have the proper packages installed, since installing the
proper packages will create /lib/modules/"release"/build on your system.
On Fedora install 'kernel-devel' (Development Package for building kernel
modules to match the kernel) from the Package Manager (System->
Administration-> Add/Remove Software).
On Ubuntu, you will need headers and tools. Try these commands:
# apt-get install build-essential linux-headers-generic
# apt-get build-dep linux
To check to see if you have this directory do this:
# ls /lib/modules/`uname -r`/build
BUILD INSTRUCTIONS
------------------
1. Setup the directory by untarring the proper tarball:
For 32 bit: hybrid-portsrc.tar.gz
For 64 bit: hybrid-portsrc-x86_64.tar.gz
Example:
# mkdir hybrid_wl
# cd hybrid_wl
# tar xzf <path>/hybrid-portsrc.tar or <path>/hybrid-portsrc-x86_64.tar.gz
2. Build the driver as a Linux loadable kernel module (LKM):
# make clean (optional)
# make
When the build completes, it will produce a wl.ko file in the top level
directory.
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 will
automaticly build the right version for your system but it can be
overridden if needed:
# make API=WEXT
or
# make API=CFG80211
INSTALL INSTRUCTIONS
--------------------
Upgrading from a previous version:
---------------------------------
If you were already running a previous version of wl, you'll want to provide
a clean transition from the older driver. (The path to previous driver is
usually /lib/modules/<kernel-version>/kernel/net/wireless)
# rmmod wl
# mv <path-to-prev-driver>/wl.ko <path-to-prev-driver>/wl.ko.orig
# cp wl.ko <path-to-prev-driver>/wl.ko
# depmod
# modprobe wl
The new wl driver should now be operational and your all done.
Fresh installation:
------------------
1: Remove any other drivers for the Broadcom wireless device.
There are several other drivers (besides this one) that can drive
Broadcom 802.11 chips such as b43, bcma and ssb. They will conflict with
this driver and need to be uninstalled before this driver can be installed.
Any previous revisions of the wl driver also need to be removed.
Note: On some systems such as Ubuntu 9.10, the ssb module may load during
boot even though it is blacklisted (see note under Common Issues on how to
resolve this. Nevertheless, ssb still must be removed
(by hand or script) before wl is loaded. The wl driver will not function
properly if ssb the module is loaded.
# lsmod | grep "b43\|ssb\|bcma\|wl"
If any of these are installed, remove them:
# rmmod b43
# rmmod ssb
# rmmod bcma
# rmmod wl
To blacklist these drivers and prevent them from loading in the future:
# echo "blacklist ssb" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
# echo "blacklist b43" >> /etc/modprobe.d/blacklist.conf
2: Insmod the driver.
Otherwise, if you have not previously installed a wl driver, you'll need
to add a security module before using the wl module. Most newer systems
use lib80211 while others use ieee80211_crypt_tkip. See which one works for
your system.
# modprobe lib80211
or
# modprobe ieee80211_crypt_tkip
If your using the cfg80211 version of the driver, then cfg80211 needs to be
loaded:
# modprobe cfg80211
Then:
# insmod wl.ko
wl.ko is now operational. It may take several seconds for the Network
Manager to notice a new network driver has been installed and show the
surrounding wireless networks.
If there was an error, see Common issues below.
Common issues:
----------------
* After the insmod you may see this message:
WARNING: modpost: missing MODULE_LICENSE()
It is expected, not harmful and can be ignored.
* If you see this message:
"insmod: error inserting 'wl.ko': -1 Unknown symbol in module"
Usually this means that one of the required modules (as mentioned above) is
not loaded. Try this:
# modprobe lib80211 or ieee80211_crypt_tkip (depending on your os)
# modprobe cfg80211
Now re-try to insmod the wl driver:
# insmod wl.ko
* If the wl driver loads but doesn't seem to do anything:
the ssb module may be the cause. Sometimes blacklisting ssb may not
be enough to prevent it from loading and it loads anyway. (This is mostly
seen on Ubuntu/Debian systems).
Check to see if ssb, bcma, wl or b43 is loaded:
# lsmod | grep "ssb\|wl\|b43\|bcma"
If any of these are installed, remove them:
# rmmod ssb
# rmmod bcma
# rmmod wl
# insmod wl
Back up the current boot ramfs and generate a new one:
# cp /boot/initrd.img-`uname -r` somewheresafe
# update-initramfs -u
# reboot
3: Setup to always load at boot time.
The procedure to make a module load at boot time varies from distro to
distro. Consult the docs for your specific distro to see how. The
following seems to work for my setup on Fedora and Ubuntu. Check your
docs to see the procedure for your distro.
Follow these steps to have the driver load as part of the boot process:
# load driver as described above
# cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless
# depmod -a
# echo modeprobe wl >> /etc/rc.local (Fedora/SUSE)
Ubuntu ships a version of wl.ko, so those need to be disabled. On my
system the were several versions, so I searched and renamed the .ko's
like this:
# sh: for i in `find /lib /var -name wl\.ko`; do mv $i ${i}.orig; done
TX POWER EXPLAINED
------------------
'iwconfig eth1 txpower' & 'iwlist eth1 txpower' set and get the drivers
user-requested transmit power level. This can go up to 32 dbm and allows
the user to lower the tx power to levels below the regulatory limit.
Internally, the actual tx power is always kept within regulatory limits
no matter what the user request is set to.
ISSUES FIXED AND WHAT'S NEW IN THIS RELEASE
-------------------------------------------
+ Added cfg80211 API support. The choice of API is done at compile time. If
kernel version >= 2.6.32, cfg80211 is used, otherwise wireless extension
is used. (End users should notice little difference.)
+ Supports Linux kernel 2.6.38
+ Fix for problem with rebooting while wireless disabled via airline switch.
+ Fixed a kernel panic observed on some 64-bit systems
HOW TO USE MONITOR MODE
-----------------------
To enable monitor mode:
$ echo 1 > /proc/brcm_monitor0
Enabling monitor mode will create a 'prism0' network interface. Wireshark and
other netwokk tools can use this new prism0 interface.
To disable monitor mode:
$ echo 0 > /proc/brcm_monitor0
ISSUES FIXED AND WHAT'S NEW IN RECENT RELEASES
-------------------------------------------
+ Supports monitor mode
+ Supports cfg80211
+ Supports hidden networks
+ Supports rfkill
KNOWN ISSUES AND LIMITATIONS
----------------------------
#72238 - 20% lower throughput on channels 149, 153, 157, and 161
#72324 - Ubuntu 8.04: cannot ping when Linux STA is IBSS creator with WEP
enabled
#72216 - Ubuntu 8.04: standby/resume with WPA2 and wpa_supplicant causes
a continuous assoc/disassoc loop (issue with wpa_supplicant, restarting
wpa_supplicant fixes the issue)
#76739 Ubuntu9.04: unable to connect to hidden network after stdby/resume
#76793 Ubuntu9.04: STA fails to create IBSS network in 5 Ghz band
KNOWN ISSUES AND LIMITATIONS IN EXTERNAL COMPONENTS
----------------------------
wpa_supplicant 0.6.3 + nl80211 + WEP - (Note: This would only affect you if
you are using wpa_supplicant directly from the command line and specify
nl80211 interface, e.g. "wpa_supplicant -Dnl80211 -ieth1 ..". If you are using
network manager GUI to connect it should work file.)
wpa_supplicant 0.6.3 might have a bug that affect WEP connections created
through nl80211. Upgrade to wpa_supplicant to 0.7.3 would solve this problem.
Ubuntu 10.10 kernel + nl80211 + WPA/WPA2 - (Note: This would only affect you if
you are using wpa_supplicant directly from the command line and specify
nl80211 interface, e.g. "wpa_supplicant -Dnl80211 -ieth1 ..". If you are using
network manager GUI to connect it should work file.)
Some kernel versions of Ubuntu such as 2.6.35-22 (released with Ubuntu
10.10) may have problems that affect WPA/WPA2 connections created through
nl80211. Upgrade to 2.6.35-25 or later should solve this problem.
HOW TO INSTALL A PRE-COMPILED DRIVER
-----------------------------------
Some of the major linux distros already supply a version of this driver, so
you don't have to compile your own. Most of the distros keep this driver
along with other proprietary or non-GPL drivers in a separate repository.
For further information see the documentation for your specific distro.
Fedora:
------
su -c 'rpm -Uvh
http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'
su -
yum update
yum install kmod-wl
Ubuntu:
------
Go to System->Administration->Hardware Drivers
Choose the Broadcom STA wireless driver
Activate
Sometimes the driver does not show up in the Hardware Drivers choices. In
this case, try reintalling the driver from the GUI or shell like this:
From the GUI:
Package Manager (System>Administration>Synaptic Package Manager). Click the
Reload button in the upper left corner of Synaptic to refresh your index then
search for and reinstall the package named bcmwl-kernel-source.
From the shell:
sudo apt-get update
sudo apt-get --reinstall install bcmwl-kernel-source
In either GUI or text case, after reinstalling, reboot your machine.
Now go back to System->Administration->Hardware Drivers
and you should see the driver enabled and working.
