我是 Ubuntu 新手。我买了一台戴尔 3537 - 预装了 ubunbtu。升级到最新更新后，我的 wifi 停止工作了。我发现https://www.kernel.org/pub/linux/kernel...able/v3.9-rc4/并安装了驱动程序。但是，我观察到以下情况：
互联网几分钟内工作正常，然后几秒钟就断开了。这种情况一直在发生。我很确定与 wifi 的连接也断开了，但这并没有反映在我的网络管理器中。我的另一台运行 Windows 7 的笔记本电脑在连接到同一网络时没有任何问题
我尝试收集一些信息，这些信息可能有助于解决我的问题。任何帮助我都会感激不尽。
它有帮助，我已经运行了 Wild Man 和 Krytarik 开发的脚本，得到了 anewguy、chili555、llua 的帮助，并提到这里 输出为 -http://pastebin.ubuntu.com/7101870/
