我已经在双启动系统上使用 Ubuntu 18.04 大约一个月了。我以前遇到过 WiFi 问题，但重启一下就能解决。然而，最近我根本无法连接到 WiFi。
输入后lspci，我得到以下信息：

如您所见，计算机使用英特尔 WiFi 驱动程序。有时，使用此命令根本不会显示它们。
我已经尝试了该答案中的所有步骤，但没有取得太大成功： 联想 X1 Carbon 第 7 代中未找到 WiFi 适配器
我刚刚安装了 Ubuntu 19.10，希望问题能够得到解决，但这也无济于事。我目前使用的是 19.10
但是我可以通过 USB 网络共享进行连接，并且过去几天 WiFi 可以工作 5-10 分钟。
此外，当我启动 Windows 时，WiFi 就可以正常工作。
任何帮助将不胜感激！
编辑 1：这是输出sudo modprobe iwlwifi && dmesg | grep iwl
输出太长，因此这里是开头和结尾的几行：
