ubuntu10.10下更新无线网卡驱动
说来，今天很郁闷。
自己很讨厌ubuntu的自动升级，于是在Synaptic中禁止linux内核升级。但是天算不如人算，不知道哪天我的ubuntu内核居然升级了。
哎，原来的linux-2.6.35-22变成了旧内核。看看我的ubuntu里面有很多旧内核：
mark@mark:~$ sudo dpkg --get-selections|grep linux libselinux1 install linux-firmware install linux-generic-pae install linux-headers-2.6.35-22 install linux-headers-2.6.35-22-generic install linux-headers-2.6.35-24 install linux-headers-2.6.35-24-generic install linux-headers-2.6.35-24-generic-pae install linux-headers-2.6.35-30 install linux-headers-2.6.35-30-generic install linux-headers-2.6.35-30-generic-pae install linux-headers-generic install linux-headers-generic-pae install linux-image install linux-image-2.6.35-24-generic install linux-image-2.6.35-24-generic-pae install linux-image-2.6.35-30-generic install linux-image-2.6.35-30-generic-pae install linux-image-generic install linux-image-generic-pae install linux-libc-dev install linux-sound-base install pptp-linux install syslinux install syslinux-common install util-linux install
顺便说一下，http://www.itmop.com/network/system/linux/12224227.html提示如何卸载旧的内核。
一直发现，我的无线网卡不是很稳定。时而连接失败时而成功，前段日子，即使掉线，也可以再连一次。但是现在掉线，需要重启电脑。其它招数一概不好使。很有可能是网卡驱动问题，于是我这样做：
mark@mark:~$ sudo lshw -C network

在-network中，看到这样一条记录，product: RTL8191SEvB Wireless LAN Controller，可以看出驱动是RTL8191SEvB。带着疑问，我又这样：
iwconfig看到，rtl8191SE-VA2的信息。这次确定驱动的版本了。
好嘞，去RTL官网下载最新驱动，下载地址：http://218.210.127.131/downloads/searchView.aspx?keyword=rtl8191se
当然，根据你自己的操作系统以及实际网卡驱动来选择下载。不要盲目下载。我下载的是：
接下来的工作，就是编译安装。
1. 解压下载的文件
解压到/home/mark/Download
2. 编译
cd Download make3. 安装
sudo make install4. 重启PC
ok，搞定！可爱的无线图标
显示正常，呵呵！
