我在 XPS 13 (9360) 上运行 Ubuntu 16.10，每次我合上盖子或将笔记本电脑置于挂起状态时，WiFi 都会停止工作，甚至连接到其他网络（尽管可以连接）也不起作用。它看起来好像已连接（显示信号和所有内容），但实际上并没有。我必须重新启动计算机才能修复它...
它在 Ubuntu 16.04 上运行正常。
谢谢！

我遇到了同样的问题，重新启动网络管理器也解决了这个问题。要自动执行此操作，请在 /etc/pm/sleep.d 中添加一个脚本，内容如下：
#!/bin/bash
case "$1" in
suspend)
# executed on suspend
;;
resume)
# executed on resume
systemctl restart network-manager.service
;;
*)
;;
esac
