Fedora21安裝Broadcom無線網卡驅動

前兩天在舊筆記本上安裝了Fedora 21 workstation 32位版本，裝好發現無線網卡不能使用（Fedora節操高），網上查了查，在fedora論壇找到了解決辦法。

分三步：

Step 1: Identify the chipset of the wireless device

第一步：識別無線網卡型號，終端運行：lspci

我的本反饋最後一行爲 10:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
即無線網卡型號爲 BCM4312

Step 2: Choose the right driver

第二步：選擇合適的驅動，原文給的選擇表如下：（我懶的看完就選了version 4那個，然後就成功了。。）

  Install       firmware                                    rndis_wlan
 version 4
 firmware

Step 3: Install the driver

第三步：安裝驅動

1. Install b43-fwcutter. This is the software package that does the extraction of the firmware from the proprietary driver.安裝b43-fwcutter，這個軟件包是用來解壓縮後面的驅動固件的。
   Code:

   su
   yum install b43-fwcutter

2. Determine which native driver is being used by the wireless card (b43 or b43legacy). The kernel is generally good about detecting a Broadcom wireless card and loading the correct driver module for it. The following terminal command will list the loaded kernel modules in alphabetical order. Look for b43 or b43legacy.檢測無線網卡使用的驅動，命令行給出的列表是按字母順序來的，注意查找B43或B43legacy（英語一般，大致這麼翻譯吧。。）
   Code:

   lsmod | sort

3. Do this step only if you need to install version 4 firmware for the b43 driver module. Copy and execute the following command lines one after the other in a Fedora terminal.這是給b43驅動安裝version 4固件的code，終端執行即可。
   Code:

   wget http://downloads.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2
   tar xjf broadcom-wl-4.150.10.5.tar.bz2
   cd broadcom-wl-4.150.10.5/driver	
   su
   b43-fwcutter -w /lib/firmware wl_apsta_mimo.o

後面還有其他版本驅動的安裝說明，我沒用到就不翻了，原帖有詳細說明。
