Dell 7480,Linux 新手。我安装了 Ubuntu 20.04 和 Win10,除了 Ubuntu 中的 Wifi 之外,它似乎可以正常工作。安全启动和快速启动被禁用。
我以为只有当我在 Windows 上执行“重启”而不是“关机”时才会出现问题(在 Windows 上 Wifi 总是可以正常工作),但现在情况已经不同了。虽然它工作了一段时间,所以我在 Ubuntu 中多次使用 Wifi。它也可以很好地通过 USB 实时运行。如果我在启动 Ubuntu 时插入网线,然后将其拔掉,Wifi 就可以正常工作。
我想我在某个地方看到过有关此类问题的内容,但现在找不到了。我运行了以下命令/诊断程序:
