我的网络与 Windows 7 上的这台计算机以及各种其他计算机和设备完美配合。我今天安装了 Ubuntu 14.04,它完美运行,除了 wifi。

当我尝试连接(wifi 图标,name_of_network)时,每隔一分钟左右就会出现一个要求输入密码的弹出窗口,但它无法连接。密码正确。

我尝试从连接列表中删除网络(wifi 图标、编辑连接),重新启动计算机并重试,但无济于事。

以太网工作完美。

我必须假设它与 Ubuntu 相关,因为无线网卡被识别并且可以扫描可用的不同网络。

我不太了解 Ubuntu 14.04,甚至无法尝试任何东西。

有什么建议?

所以,我的问题得到了解决。我不太确定如何,但这是我所做的:

sudo service network-manager restart
