Wireless

Lenovo offers different options in paragraph wireless hardware:
T400提供了两种无线硬件

Intel chipset

Wifi link 5100 and 5300

The drivers are included in the 2.6.27 kernel. However, it's important to make sure that you have the correct firmware. I installed the iwlwifi-5000-ucode. See this section for more details.

Realtek chipset

Rtl8192SE

11b/g/n Wireless Lan Mini-PCI Express Adapter II
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8172 (rev 10)

可以知道R28的无线型号为：Rtl8192SE

两种解决方案
目前没有任何in-kernel 驱动支持这个芯片组，有两种可选的方案：
1 a Linux driver available for download from Realtek
2 ndiswrapper. (Ubuntu 10.4 support it now).

方案一 Realtek r8192se_pci Driver

Get the driver from Realtek's website (r8192se_pci):

Rtl8192SE下载地址（32 & 64 bits）: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=21&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true
或http://launchpadlibrarian.net/51407658/rtl8192se_linux_2.6.0017.0705.2010.tar.gz

编译安装

1 untar; make; make install; reboot

2、解压，make

3、复制驱动文件

在HAL/rtl8192下能够找到r8192se_pci.ko文件，cp至/lib/modules/`uname -r`/kernel/drivers/net/wireless/

gwlee@lingyun:~/rtl8192se_linux_2.6.0017.0705.2010$ sudo cp HAL/rtl8192/r8192se_pci.ko /lib/modules/2.6.24-24-generic/kernel/drivers/net/wireless/

4、复制固件

将固件相关文件，即firmware/RTL8192SE目录，cp至/lib/firmware/`uname -r`/

sudo cp -r firmware/RTL8192SE/ /lib/firmware/2.6.24-24-generic/

5、执行命令depmod -a重新扫描module依赖关系

sudo depmod -a

6、加载驱动

执行命令modprobe r8192se_pci加载该module，这一步完成以后NetworkManager就可以搜到无线网络并进行连接了。

sudo modprobe r8192se_pci

问题：

I found it would not build unless I installed kernel26-headers and created a directory at /etc/acpi/events.

The reboot step is also unnecessary, it is available for modprobing immediately.

测试：

I test it with:

netcfg
standar commands:

ifconfig wlan0 up
iwlist wlan0 scan iwconfig wlan0 essid MySsid wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf dhcpcd wlan0

There is also a package available in the AUR: http://aur.archlinux.org/packages.php?ID=34281

方案二 Ndiswrapper option:

If you have a 32-bit version of arch, it should be possible to get it working with ndiswrapper:

Download this .exe file: http://www.station-drivers.com/telechargement/realtek/wifi/rtl-8191se_1080.7.0520%28www.station-drivers.com%29.exe
Install the extra/p7zip package and use the included utility 7z to extract the contents of the .exe:

7z x rtl-8191se_1080.7.0520(www.station-drivers.com).exe

Copy the files net8192se.inf and rtl8192se.sys from the 91_92_SE_Driver/Win2K directory to a location of your choosing.
Proceed with the normal ndiswrapper installation procedure.

Unfortunately, if you are running a 64-bit version of arch then it seems you are out of luck currently; the WinX64 drivers included in the above package do not work. (不支持 64-bit )
