在 HP 840 G6 笔记本电脑上全新安装 Ubuntu 22.04。在 BIOS 中关闭快速启动。无双启动；未安装 Windows；安装 Ubuntu 时格式化硬盘。我读到的似乎是双启动错误 - 但我没有这个：https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled
飞行模式已关闭。我按照此页面上的说明安装了英特尔驱动程序：https://itslinuxfoss.com/install-intel-wifi-6-ax200-driver/。以太网（有线）工作正常。我甚至在系统管理器中都看不到 Wifi 图标。
以下是我检查的内容：

答案1
认为这个问题已经解决。我不确定发生了什么，但大约两周后我重启了电脑，然后就能使用 Wifi 了。
