我刚刚安装了 Linux Mint 17.2。自从安装以来，我注意到我的 WiFi 连接断开了，但并没有断开。WiFi 在 Windows 上运行良好。在此期间，我无法 ping 任何服务器或加载任何网站。这似乎是随机发生的。

到目前为止，我忽略了 IPv6，但毫无效果。我还遇到了一个有同样问题的人，他有一张 Realtek 卡。/etc/modprobe.d/我想他被指示用与他的 Realtek 卡匹配的文件名写入以下内容。我也做了类似的事情：
nanor@teabags ~ $ cat /etc/modprobe.d/rtl8192ce.conf
options rtl8192ce fwlps=N ips=N
我已经重启了，但似乎没什么变化。如能得到任何帮助，我将不胜感激！

您可以使用兼容 Linux 的 USB 无线适配器。这解决了我旧笔记本电脑上的问题。有几个品牌效果很好，下面是一个简短的列表
TP-Link TL-WN722N 150Mbps 高增益无线 USB 适配器
潮流网 TEW 664UB
