在Ubuntu上通过命令行连接到WEP无线networking

我是networking和Linux的新手。 我现在试图通过我的Ubuntu 8.10上的命令行连接到WEP无线networking，因为networkingpipe理器不支持64位WEP。

（1）首先closuresnetworkingpipe理器，然后尝试连接到无线networking，无线networking是糖果，密码为5673212741，但是失败，如下所示。 信号不是很强，但我可以在Windows 7中连接到它。我想知道为什么以及如何正确地为Ubuntu做到这一点？

$ sudo /etc/init.d/NetworkManager stop * Stopping network connection manager NetworkManager [ OK ] $ sudo iwconfig wlan0 essid candy opendo iwconfig wlan0 key 18018ce78e open $ sudo iwconfig wlan0 key 5673212741 open $ sudo dhclient wlan0 There is already a pid file /var/run/dhclient.pid with pid 9971 killed old client process, removed PID file Internet Systems Consortium DHCP Client V3.1.1 Copyright 2004-2008 Internet Systems Consortium.

（2）一个不太重要的问题：为什么在closuresnetworkingpipe理器之后扫描无线networking不起作用？

 $ sudo /etc/init.d/NetworkManager stop * Stopping network connection manager NetworkManager [ OK ] $ sudo iwlist wlan0 scan wlan0 Interface doesn't support scanning : Network is down 

感谢致敬！

• 使用Ubuntu 10.04作为接入点
• wireshark没有看到WiFi上的所有数据包
• 我需要“无线接入点”还是路由器？
• 是否有可能得到一个模块来支持（有时）报告错误的PCI ID的设备？
• Wifi主机不能互相联系（但在同一个VLAN上的有线主机可以）

 sudo /sbin/ifconfig wlan0 up sudo /sbin/iwlist wlan0 scan sudo /sbin/iwconfig wlan0 essid "candy" sudo /sbin/iwconfig wlan0 key 4104672851 sudo /sbin/iwconfig wlan0 enc on
