未找到 WiFi 适配器、Dell XPS 9570、Killer 1350 卡

Dim*_*kis 3 wireless networking dell drivers

Linux 新手在这里。我已经在我的机器上安装了 Ubuntu 18.04.1 和 Windows 10。一切都顺利运行了大约一个星期,然后突然之间,网卡就决定要死在我身上了。安装固件并重新启动网络管理器后,仍然无法通过 BIOS、Windows 或 Ubuntu 访问该卡。我什至看不到它。

所以我从戴尔那里买了一张新卡(因为笔记本电脑还在保修期内),但他们只能用同一张卡来替换它。现在,我有蓝牙,并且当我启动到 Windows 时该卡可以工作。但是,在WiFi下,它仍然说没有WiFi适配器。

有人可以帮忙吗?

一些进一步的信息:
