没有找到 Wifi 适配器？

我使用的是ubuntu 18.4。我的系统死机并重新启动，从那时起我的 wifi 就无法工作了。我尝试了中建议的解决方案这个问题但无济于事。我有 Windows 双启动，但它在 Windows 中也不起作用。这是输出sudo lshw -class network

答案1

从 lsshw 的输出（其中显示网络已禁用）和 Windows 无法工作的迹象来看，很明显它与硬件有关。

您误按了硬件开关/按钮禁用了 WiFi 适配器服务。再次按下开关。 WiFi 应该会自行出现，如果没有，请稍后重新启动。

答案2

好吧，伙计们，这是一个硬件问题。无线网络卡无法使用。对不起。
