需要在 Centrino N 6200 上手动启用无线网络

当我运行 Ubuntu 时，它会自动连接到无线网络，但无法连接到互联网，直到我禁用然后启用网络，

我需要解决这个问题，帮帮忙。

我运行时得到这个输出lspci：

答案1

不幸的是，我没有答案，但我的 Vaio 笔记本电脑上也存在同样的问题，它配备了 WiMax 6250 wifi 适配器。我最近发现，我必须删除 SSID 及其配置并重新添加，然后它才能开始工作。否则，我会从路由器获得一个有效的 IP 地址，但无法 ping 通、检查路由等。什么都没有。我认为这是一个错误，但目前还不能确定它的位置。

答案2

（这完全是猜测）

尝试安装新的驱动程序反向移植，有时驱动程序的修复会反向移植到稳定版本。安装此软件包（或单击链接）：

Linux-backports-模块-cw-2.6.39-natty-通用

然后重新启动并查看是否有帮助。
