最近在新买的笔记本上安装了Ubuntu20.04，但是无法连接wifi，提示“未找到wifi适配器”。
以下是一些可以帮助您更好地理解该问题的信息。
无线适配器：英特尔® Wi-Fi 6 AX210 160MHz（购买时预装）
笔记本电脑：Galaxy Book Flex 2
(*** 我去了三星服务中心，担心是硬件问题，但结果发现无线适配器本身没有问题。***)
操作系统：Windows 10 和 Ubuntu20.04 双启动
内核版本（
# uname -r）：5.13.0-051300-generic驱动固件（保存在/lib/firmware中）：iwlwifi-ty-59.601f3a66.0.tgz
(*** 由于当我第一次注意到此问题时我的无线适配器没有正确的 Linux 固件，因此我将内核从 5.8 升级到 5.13，并将最新的驱动程序放在 /lib/firmware 中，然后使用命令 #sudo modprobe iwlwifi 加载驱动程序 ***)
不同操作系统上的无线性能：WiFi 在 Windows 10 上运行良好，但仅在 Ubuntu 上，从一开始就不行。
其他设置：
禁用 Windows 上的“快速启动”选项
从 grub 禁用“安全启动”

几天来，我尝试了网上的很多方法，但似乎都没有用。任何建议都将不胜感激。非常感谢。
最好的，
