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

make

3. 安装

sudo make install

4. 重启PC

ok，搞定！可爱的无线图标显示正常，呵呵！
