Ubuntu 16.04 中 Wifi 网络不可见

我有一台戴尔 xps，带有 win10 双启动和 ubuntu 16.04。从我的 windows 启动关闭并重新启动我的 ubuntu one 后，wifi 网络不可见，甚至没有无线网络符号。

我努力了

sudo systemctl restart network-manager

sudo apt install linux-generic-hwe-16.04 linux-firmware

尽管输出rfkill list是

0: hci0: Bluetooth 
    Soft blocked: no 
    Hard blocked: no 
1: dell-wifi: Wireless LAN 
    Soft blocked: no
    Hard blocked: no 
2: dell-bluetooth: Bluetooth 
    Soft blocked: no 
    Hard blocked: no

的输出sudo lshw -C network仍然是

这真是令人沮丧，因为在启动 Windows 之前，WiFi 运行正常。任何帮助都非常感谢。
