在 DELL precision 电脑上安装 ubuntu 18.04 时出现“未找到 Wifi 适配器”

我使用DELL Precision 3541。Wifi Adapter 是 [Intel's Wireless-AC 9560]

重启笔记本电脑后，我收到“未找到 Wi-Fi 适配器”的提示。因此我尝试了 StackOverflow 中提到的几种解决方案。但当我输入 sudo lshw -C network 时

我收到了这个回复

此外，击中后rfkill list我得到了不在硬阻断用于无线局域网。

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

没有逻辑名称我的 wifi 适配器不支持该命令。因此我无法使用该ip link set <logical name> up命令。

有什么方法可以启用我的笔记本电脑上的 Wi-Fi 适配器吗？

运行后更新 dmesg | grep iwl

答案1

我尝试了一些随机方法。不知道效果如何。只需按照步骤操作即可。

1.重新启动我的笔记本电脑。

2.进入BOIS设置（F12）。

3.然后在无线部分内，我完全禁用了 WLAN。

4.启动成功后，再次重启笔记本电脑。

5.进入BOIS设置并启用WLAN。

最后，当笔记本电脑打开时，一切又恢复正常。
