还是无线网卡，资料齐全，大家分析下！（停止求助！）

各种驱动齐全，为什么就是不能连接无线信号呢？
无线网卡是pci的，主板集成一个网卡。
无线网卡是tp-link tl-wn510g wireless cardbus 芯片Atheros Communications.Inc
开机之后networkmanager 会自动搜索网络信号，里面有三个信号，会一个个的尝试连接，但是都不成功，最后就成了电脑小图标上一个红色的叉号。

以下信息都是没有连接有线的情况下得到的。
1，先看看硬件的信息

5，再看eth0的情况

代码： 全选

:~$ iwlist eth0 scan
eth0      Interface doesn't support scanning.
6，看lo的情况

代码： 全选

:~$ iwlist lo scan
lo        Interface doesn't support scanning.
7，在networkmanager中有三个无线网络的信号，可是点击连接之后，尝试一段时间就会失败。
8，madwifi也装了。
9，网上说的方法基本都做了一次了，但是都没有成功。
10，之前曾经无线网络连接成功2次，但是现在不能连接。

我在想会不会是集成的网卡和无线网卡之间有冲突呢？？大家帮我分析下！谢谢！

看上去无线网络已经连接成功了，可能是因为那个ap没有dhcp，自己指定ip试试。

我们学校是客户端认证的方式。我的ip我发现是固定的，已经和我的MAC帮定了吧。具体如何指定呢？我试过一些网上的方法，也没有主意了。能不能详细点？谢谢！

你试试

代码： 全选

dhclient ath0
能不能给你自动分配一个ip，不行的话用

代码： 全选

ifconfig ath0 xxx.xxx.xxx.xxx
手动指定ip，还需要

代码： 全选

route add default gw xxx.xxx.xxx.xxx
手动指定路由器ip，还需要在/etc/resolve.conf加入一行

nameserver xxx.xxx.xxx.xxx
手动指定dns服务器ip

dhcp失败了，你要自己用ifconfig手动指定ip。比如：

sudo ifconfig ath0 219.216.46.201
之后你试试

真的是要崩溃了。刚开始的时候有2次是自己连接到无线信号，然后我运行xrgsu就打开网页了。
现在是到处问题啊………………

试下sudo iwconfig ath0 essid CMU_GuolufangI
另外，怀疑楼主没有屏蔽本身的网卡驱动，ndis没生效
ndis默认的设备名是wlan0

发表于 ： 2007-03-21 17:38
由 youngcmu
谢谢回复！
ndis应该是后装的，那么原来的驱动怎么屏蔽呢？
不要嫌我笨啊，我现在实在是不愿意搜索了，一搜索全是熟悉的结果，看到了就像吐啊！！！！！！！！
而且我也是在xp下上网找东西，基本是有个方法就重启进入ubuntu 尝试一下，可怜我的电脑了，一天下来重启N次啊！

LZ,我又仔细的看了两遍你的帖子,你的网卡驱动应该是没问题的，能正常驱动的

那么，你的上网方式是什么样的？

我的上网是通过学校的无线网络。在xp下，我需要一个锐捷的客户端来输入我的用户名和密码，然后连接就可以登录了。每次我都是在xp里看回复，再去ubuntu修改……
