前段时间买了一台 Acer Aspire V3-371，装了 Kubuntu 14.04，大部分功能都很好，就是经常连不上 wifi。
在家里，连接太差了，即使我坐在路由器旁边，也根本无法使用它。但是，当我在大学时，它工作正常，那里有很多路由器，而且据我所知这是一个公共网络。似乎我无法在家里正确连接到路由器。
有人能提供一些有用的提示或链接吗？

我也有同样的电脑。
您必须编辑/etc/modprobe.d/ath9k.conf（或创建）
sudo nano /etc/modprobe.d/ath9k.conf
并添加以下行：
options ath9k nohwcrypt=1
然后重新启动计算机。
