我看了一下，10.4的无线连接最高也只有wpa及wpa2，那么，WPA-PSK/WPA2-PSK加密有什么办法可以连接么？
谢谢

在无线路由器里设置使用WPA-PSK/WPA2-PSK加密连接就行了吧。我就是这样操作的，本本上没有做任何设置，自动转成WPA-PSK/WPA2-PSK加密连接了。（在本本上显示是WPA/WPA2连接，但在路由器上显示是WPA2/PSK连接）

呃，但是死活连不上。

恭喜你！遇到 通病了。。。不是 你一个人出这样的故障。。。

俺参考这里http://www.codealias.info/technotes/wir ... inux_setup ，配置成功
俺用的是kubuntu 10.0.4,默认已自带wpa_supplicant 命令，所以跳过了安装步骤

为防止以后访问出错，先copy下来


Steps for configuring and using WAP2/PSK on your wireless device

1. Install wpa_supplicant
wpa_supplicant is an EAP/WPA/WPA2 supplicant available for Linux, Windows and Unix systems. Windows binaries are available from the website. The following are two methods for installing wpa_supplicant under linux and FreeBSD.

Install using package managers

Under debian compatible linux distributions, wpa_supplicant can be installed by typing
Under FreeBSD
or
Compile from source

* Downloaded wpa_supplicant from here here
* Extract the archive
* Create a .config file
* Build and install


2. Configure

Edit the wpa_supplicant configuration file (e.g. /etc/wpa_supplicant.conf), ant put the following
* “PSK” is the PSK generated from the password shared with the wireless access point
* “YOUR-SSID” is the (B/E)SSID of the wireless access network.

To generate the wpa_supplicant.conf file, the wpa_passphrase tool can be used as follows.

3. Run the wpa_supplicant daemon
Where IFACE is the name of your wireless interface.

* Check that you are associated
* Get an IP address

4.Automating

In order to avoid typing all these commands each time you reboot or want to connect to your wireless network, you can (under linux) use the /etc/network/interfaces file to automatically handle network association and IP address acquisition. For this purpose, put the following in /etc/network/interfaces

我用的是ubuntu910，安装wpasupplicant时提示已经是最新版本了，但就是配置不成功，执行完wpa_supplicant -B -i wlan0 -Dwext -c /etc/wpa_supplicant.conf，总是提示not assoisated，不知道是什么原因？网卡是broadcom4318芯片，dell 1370 mini pci 无线网卡。

将执行的命令贴上来。
hao@lihao-laptop:~$ sudo wpa_supplicant -B -i wlan0 -Dwext -c /etc/wpa_supplicant.conf
lihao@lihao-laptop:~$ iwconfig wlan0
wlan0 IEEE 802.11bg Mode:Managed Frequency:2.437 GHz

lihao@lihao-laptop:~$
其中wpa_supplicant.conf，用sudo wpa_passphrase YOUR-SSID PASSWORD命令其中YOUR－SSID分别用ESSID和BSSID生成过配置文件试过都是相同的结果。

看来我的w311u网卡的问题很快就要见到曙光了。maybe，= 我回到office 试试看。 thx

斗胆说一句，如果还是这么多的无线网卡问题，换回 debian testing/sid 吧，如果还是不行，就换卡吧

在debian不会让你配置wapsupplicant的，因为那不需要

我现在用红旗桌面7.0版，直接就可以连上wpa-psk/wpa2-psk的无线网络，什么都不需要配置，等ubuntu哪个 版本解决了这个问题再考虑使用吧！

测试表明，我之前的910之所以连接不上wpa/psk-wpa2/psk的网络，是由于我在rc.local中修改了网卡mac地址的原因，将mac地址改回来之后就可以顺利连上了！

我执行完命令之后就这样了..
什么回事..

都11.04了，还存在这个问题，真是悲剧啊

我的之前也是链接不上，不过事因为隐藏了ssid，先打开ssid使ubuntu能够搜索到就连上去了，之后再隐藏就好了
