Realtek RTL8188CU芯片无线网卡的Linux驱动如何安装？（已解决）

[宇文拓]

如题，本人购买了傻多（Sapido，台湾品牌）的迷你型无线网卡AU-4912，产品官网如下：http://www.sapido-china.com/productau4912o.htm，之所以选择该产品是因为产品介绍中是支持Linux的，而且在官网的驱动下载页面也有Linux版本的驱动可以下载，但是本人是Ubuntu菜鸟，不懂如何在Ubuntu下安装该驱动，现将下载的驱动中的说明文档发上来，请教各位高手，谢谢！！





===============================================================================
Software Package - Component
===============================================================================
1. ReleaseNotes.doc

2. document/

3. driver source code

3.1 Makefile - to build the modules

3.2 Script and configuration for DHCP:
"wlan0dhcp"
"ifcfg-wlan0"

3.3 Example of supplicant configuration file:
"wpa1.conf"

3.4 Script to run wpa_supplicant
"runwpa"

3.5 Script to clean relative modules
"clean"

4. wpa_supplicant/wpa_supplicant-0.6.9_wps_patch_20100201.zip
The tool help the wlan network to communicate under the
protection of WPAPSK mechanism (WPA/WPA2) and add WPS patch


==================================================================================================================
User Guide(1) - connecting wireless networking using "Network Manager" GUI utility (For PC Linux)
==================================================================================================================
(1) Network Manager is a utility attempts to make use of wireless networking easy.

(2) Notes: if you want to use the following command-line method to connect wireless networking,
please disable the "Network Manager", because "Network Manager" will conflict with method of command line .

==================================================================================================================
User Guide(2) - Using the wpa_cli & wpa_supplicant tools (For embedded Linux)
==================================================================================================================

Please refer to the document/wpa_cli_with_wpa_supplicant_20091227.doc

==================================================================================================================
User Guide(3) - Set wireless lan MIBs in Command Line (Legacy command - Not recommend)
==================================================================================================================
This driver uses Wireless Extension as an interface allowing you to set
Wireless LAN specific parameters.

Current driver supports "iwlist" to show the device status of nic
iwlist wlan0 [parameters]
where
parameter explaination [parameters]
----------------------- -------------
Show available chan and freq freq / channel
Show and Scan BSS and IBSS scan[ning]
Show supported bit-rate rate / bit[rate]

For example:
iwlist wlan0 channel
iwlist wlan0 scan
iwlist wlan0 rate

Driver also supports "iwconfig", manipulate driver private ioctls, to set
MIBs.

iwconfig wlan0 [parameters] [val]
where
parameter explaination [parameters] [val] constraints
----------------------- ------------- ------------------
Connect to AP by address ap [mac_addr]
Set the essid, join (I)BSS essid [essid]
Set operation mode mode {Managed|Ad-hoc}
Set keys and security mode key/enc[ryption] {N|open|restricted|off}

For example:
iwconfig wlan0 essid "ap_name"
iwconfig wlan0 ap XX:XX:XX:XX:XX:XX
iwconfig wlan0 mode Ad-hoc
iwconfig wlan0 essid "name" mode Ad-hoc
iwconfig wlan0 key 0123456789 [2] open
iwconfig wlan0 key off
iwconfig wlan0 key restricted [3] 0123456789
Note: Better to set these MIBS without GUI such as NetworkManager and be sure that our
nic has been brought up before these settings. WEP key index 2-4 is not supportted by
NetworkManager.

===============================================================================
Getting IP address (For User Guide(2) & User Guide(3))
===============================================================================
After start up the nic and connect to AP successfully, the network needs to obtain an IP address
before transmit/receive data.
This can be done by setting the static IP via "ifconfig wlan0 IP_ADDRESS"
command, or using DHCP.

If using DHCP, setting steps is as below:
(1)check if the WiFi had connected to an AP via "iwconfig" command
$> iwconfig

(2)run the script which run the dhclient
$> ./wlan0dhcp
or
dhcpcd wlan0
(Some network admins require that you use the
hostname and domainname provided by the DHCP server.
In that case, use
dhcpcd -HD wlan0)


===============================================================================
WPAPSK/WPA2PSK - using wpa_supplicant (For User Guide(3))
===============================================================================

Wpa_supplicant helps to secure wireless connection with the protection of
WPAPSK/WPA2PSK mechanism. Please refer to the document/wpa_cli_with_wpa_supplicant_20091227.doc

===============================================================================
WPS - PIN & PBC methods
===============================================================================

(*) Please refer to the document/wpa_cli_with_wpa_supplicant_20091227.doc

===============================================================================
Power Saving Mode
===============================================================================

(1) in order to enter PS Mode, you need to add the parameter of "power_mgnt=1" when executing "insmod 8192cu.ko" :
$>insmod 8192cu.ko power_mgnt=1
or
$>insmod 8192cu.ko power_mgnt=2

(2) Notes:
power_mgnt=0 ;//default, disable PS
power_mgnt=1 ;//enable PS, MIN_PS Mode
power_mgnt=2 ;//enable PS, MAX_PS Mode

3.2 Script and configuration for DHCP:
"wlan0dhcp"
"ifcfg-wlan0"


这个步骤是什么意思，具体怎么操作？？

[宇文拓]

等待答复。。。。

[宇文拓]

高手在哪里哦。。。

[宇文拓]

一夜过去了，还没有等到高手现身啊。。。

[宇文拓]

气愤！！上厂家官网的线上服务，一个是通过MSN的，一个是通过QQ的，MSN的是台湾的工程师，QQ的是大陆的工程师，都不会在Linux下安装驱动！还当我皮球一样踢来踢去！！！本来对傻多的印象挺好的，因为之前家里购买的无线路由器就是用这个牌子的，现在觉得太烂了！！！！还不如买TP-Link的无线网卡，大个一点就大个一点，至少Ubuntu 10.10已经可以支持了。郁闷！！！

[宇文拓]

刚刚在Ubuntu下用Teamviewer让台湾的工程师远程过来安装，结果也是没有结果，答复得让他们在公司搭建测试环境，下周再给我答复，唉，只能再等等了。

[宇文拓]

很纳闷的一件事情，为什么我从昨天发到现在，没有高手可以回复，不求给答案，哪怕一点提示都OK，唉，心凉。。。

[lijiwe24]

realtek的芯片，解压后，编译安装：
make
sudo make install
sudo reboot

重启后应该就可以用了，不过提醒你，realtek的官方驱动就是个杯具

如果发现不行，安装ndiswrapper，在ndiswrapper里面调用这个网卡的XP驱动应该可以

其他命令就不要搞了，安装重启后直接用系统的网络管理器进行管理就好了

[宇文拓]

感谢9楼的答复，不过我后来和厂家联系上之后，由台湾的工程师帮我远程协助安装成功了。具体的安装方法如下：

1、使用root账户登录，将下载的驱动程序解压到某临时目录下；
2、在终端下进入驱动的文件夹，然后执行“make”；
3、执行“.clean”；
4、执行“insmod 8192cu.ko”，完成。


附整个操作步骤的终端命令如下：
注：我的驱动程序解压在/mnt目录下，红色字体为输入的命令。
