适用于 Realtek b852 的 Wifi 适配器

我购买了一台配备 Ryzen 5 处理器的新笔记本电脑，并安装了 Ubuntu 20.04.5 LTS。我按照本指南设置了我的 wifi 适配器：在 ubuntu 22.04 中未找到 wifi 适配器 realtek RTL8852BE WiFi 6 802.11ax PCIe。

但是，构建之后rtl8852be，当我尝试时sudo modprobe 8852be，它给出了错误modprobe: ERROR: could not insert '8852be': Operation not permitted。

$ lshw -C network

关闭安全启动后重新启动时，我现在能够连接到 WiFi。
