新装的10.04,不能上网,网卡是AtherosAR5001

大家好,我是新手,问题愚蠢请见笑!

一直都想用Ubuntu,但是,关于网卡的问题一直都没搞清楚。

以前装的9.10,但是上网非常慢,不知道结果,刚刚重新装了一个10.04。结果问题依旧。

装完后进入系统,系统能够识别网卡(我用无线上网)。然后我就连接到路由器了,也能成功。
但是这时,打开浏览器,输入Google.com。半天没有得到回应。

这时我打开了一个终端,ping了一下网关,结果让我大吃一惊。延迟竟然是400ms!
我在同一台机器的windows上ping网关,延迟是1-2ms!

随后,我ping了一下外网(baidu),结果更让我吃惊,刚开始的几个包是1000ms-1200ms。
返回了5-6个包后,延迟达到了10000ms。10个包后就没有返回了。

lspci了一下,结果给大家

是不是需要在哪里进行一下设置?才能让我的网卡正常工作?

PS:在windows系统下笔记本的无线网卡指示灯是亮的。
Ubuntu下指示灯不亮,但能够工作,只是速度太慢了。。。
有线网卡未测试。

是否是 IP 冲突?
