[问题]高手...看看这个无线怎么了.

帖子 爱上那只猪 » 2008-07-27 10:56

我是一个ubuntu爱好者,现在我遇到一个问题,找了好几天资料都没办法解决.我在QQ群里也问了,可惜没人帮得上我啊!

我装了ubuntu之后,我自己的linksys G24的无线网卡可以驱动,并且能够找到无线网络.我能连接上去..给自己配置好IP,网关,DNS之后,我只能拼通自己的IP,怎么也拼不到网关.就是无线AP这样我就不能上网...

下面给你看一些我拿出来的信息:
我的网卡MAC地址: 00:18:f8:32:44:47 无线路由的MAC:00:1e:8c:93:ca:dc
这是interfaces里的内容:
auto lo
iface lo inet loopback

iface wlan0 inet static
address 192.168.10.200
netmask 255.255.255.0
gateway 192.168.10.254
wireless-key 827d378648ec516fc67c12e65d7782aba23db19adf8d1320273005b6093d6c41
wireless-essid yishion

auto wlan0

然后我用了一些命令找出些东西:
beyoung@beyoung-ubuntu:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
wmaster0 no wireless extensions.

楼主用下面的方法试一试:

把interfaces里的
wireless-key 827d378648ec516fc67c12e65d7782aba23db19adf8d1320273005b6093d6c41
wireless-essid yishion
两行删掉

/etc/rcS.d/S40networking restart

然后
sudo iwconfig wlan0 essid "yishion" key (你的密码)
启动接口
sudo ifconfig wlan0 up

在上面的key处,如果你用的是ASCII的密码的话,在你的密码前面加's:'

iwconfig
查看Link Quality:这里,还是0的话就没连上。
可以

sudo iwlist wlan0 scan
扫描无线接入点的信标桢
看看channel项,把channel参数也传给wlan0

sudo iwconfig wlan0 channel n
