fast FW150US USB無線網卡Linux驅動安裝

由於筆記本沒有自帶無線網卡，所以買了一塊fast FW150US USB無線網卡。該網卡只自帶了window下的驅動，經過一番折騰，終於安裝好了Linux下的驅動，在此記錄以便以後遇到同樣問題能夠快速解決。

首先查看網卡型號，如下：

在此看到芯片型號爲RTL8188CUS，使用google可以找到該芯片驅動下載地址：

http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&ProdID=274&DownTypeID=3&GetDown=false&Downloads=true#2742

此時剩下的就是下載代碼，編譯，安裝，重啓系統即可。

之前擔心找不到Linux下驅動，現在已經安裝好驅動並發表該博文，又一次感受到Linxu的強大，一定要學好Linux！

今天（2012-12-15）新編譯並安裝了內核2.6.34.13，直接在原來編譯基礎上make install安裝驅動，重啓系統之後發現usb無線驅動不工作。原來驅動程序都是直接依賴內核代碼的，內核換了，需要重新make纔行。卸掉原來驅動，重新make，make install之後usb無線網卡工作正常。
