我可能应该直接说我是 Ubuntu 新手。几天前,我安装了 13.10 和 Windows 7,除了 wifi 之外,我已经设法解决了所有小问题。
使用以太网电缆,我的互联网连接正常。我可以连接到 wifi,它告诉我信号良好,但大多数时候我无法加载任何内容,系统监视器告诉我我没有发送和接收任何内容。
问题出在 Ubuntu 的某个地方。它在 Windows 7、我的 Android 手机和我室友的所有笔记本电脑上都运行良好。我知道我不是唯一遇到这个问题的人,但我看到的修复方法要么不起作用,要么我对它们了解不够,无法执行。帮忙吗?
编辑:sudo killall NetworkManager
有时有效,谢谢你的提示,但我必须每隔几分钟就这样做一次,这真的不切实际。
