hp nc6000的w500无线网卡驱动问题,在线等。

[ty3247]

大家好，我是一个ubuntu的新手，昨天费了半天得劲将中文输入搞定，但是今天想驱动无线的网卡，该网卡在系统中已经被识别了，由于我的AP是linksys的wrt54g，是加了密的，我的web密码是对的，目前的问题是不能获的ip,但在 windows中是正常的，我用命令看到如下的信息：
ifconfig ath0

请各位大虾帮我看看，问题大概在哪，小弟在线等啊，谢谢了！

调试无线网络：
1、首先我们要在系统－－》系统系统管理－－》联网的连接中看到自己的无线设备，就像我的无线设备是ath0,选择其属性，在打开的对话框中选上启用该连接，连接设置的配置中选为dhcp，不用填其他的项目，然后将其激活。

2、用sudo iwlist ath0 scan命令扫描所有的无线网络。
ath0 Scan completed :
Cell 01 - Address: 00:0C:41:9D:3D:2D
ESSID:"linksys"
Mode:Master
Frequency:2.437 GHz (Channel 6)
Quality=48/94 Signal level=-47 dBm Noise level=-95 dBm
Encryption key:on
Bit Rates:1 Mb/s; 2 Mb/s; 5 Mb/s; 6 Mb/s; 9 Mb/s
11 Mb/s; 12 Mb/s; 18 Mb/s; 24 Mb/s; 36 Mb/s
48 Mb/s; 54 Mb/s
Extra:bcn_int=100
3、用获得的AP信息来对ath0进行设置：
ty@tonylinux:~$ sudo iwconfig ath0 essid linksys
ty@tonylinux:~$ sudo iwconfig ath0 mode managed
ty@tonylinux:~$ sudo iwconfig ath0 channel 6
ty@tonylinux:~$ sudo iwconfig ath0 enc 15ADE315F326F**********
其中channel必须与你用扫描命令看到的通道一致。
4、获得dhcp client ip
sudo dhclient ath0

DHCPACK from 192.168.1.1
bound to 192.168.1.108 -- renewal in 34542 seconds.
5、用ifconfig就可以看到获得ip
ty@tonylinux:~$ ifconfig
ath0 Link encap:Ethernet HWaddr 00:0F:20:95:67:9E
UP BROADCAST MULTICAST MTU:1500 Metric:1

到此网卡正常。
