Ubuntu 14.04 - Hp pavillion dv5-2239la 无法加载网页

我最近在我的笔记本电脑上安装了 Ubuntu(Linux Mint 17.1 Cinnamon x64)

现在,我通过接入点连接到路由器来扩大我家里的区域。

注意:Ubuntu 直接连接到路由器即可正常工作。

因此,当我尝试加载任何网页 Firefox(尝试连接)时,但不会有网页响应。

通知区域图标标记信号良好,没有问题。

我认为可能是代理、IP、DCHP 问题,但我不知道如何诊断它。

任何想法?

答案1

由于您有两个无线适配器(一个内置,一个 USB),并且它们同时处于活动状态,因此您需要在给定时间选择其中任何一个。

由于我们已经将内置适配器标记为非托管,因此可以通过以下命令来找到问题的根源:

echo -e '\n[keyfile]\nunmanaged-devices=mac:CC:52:AF:10:27:41' | sudo tee -a /etc/NetworkManager/NetworkManager.conf
sudo service network-manager restart

network-manager现在,我们首先需要通过以下命令重新激活内置适配器(或任何其他先前标记为未管理的适配器)作为可管理的适配器:

sudo sed -i -e '/keyfile/d' -e '/unmanaged/d' /etc/NetworkManager/NetworkManager.conf
sudo service network-manager restart

现在所有设备均可使用,如果您不连接 USB 适配器,则将使用内置适配器,您无需更改任何内容。

如果您连接了 USB 适配器,那么我们可以假设您想要使用它并关闭内置适配器。要禁用内置适配器,请运行以下命令:

sudo nmcli con down uuid "f6f68a63-9e7d-43d0-8097-efcd0ccc230e"

现在,当您使用完 USB 适配器后,您需要发出以下命令来再次启用内置适配器:

sudo nmcli con up uuid "f6f68a63-9e7d-43d0-8097-efcd0ccc230e"

请记住,内置程序将在重启时自动启动。

答案2

两周后。但我解决了这个问题:)。

如果有人遇到同样或类似的问题。

我停用了私有的博通驱动程序并重新启动了 ubuntu,显然默认内核驱动程序在这种情况下似乎更有用,我一直在使用博通的私有驱动程序,因为系统设置中的驱动程序应用程序建议我升级到私有的。

因此,只需恢复默认的 Broadcom 驱动程序,它就可以与我家和学校的路由器和接入点一起使用。
