我的笔记本电脑（HP 笔记本电脑 14-ck1xxx）附带RTL8821CE 网络控制器。当我跑步时，lspci | grep Network我得到：

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

我无法让 Wi-Fi 正常工作。到目前为止我做了什么：

1. 在https://github.com/tomaspinho/rtl8821ce下载 repo 。
2. 解压缩文件并将文件夹从 重命名rtl8821ce-master为rtl8821ce.
3. 在终端中运行以下命令：
   • cd Downloads/rtl8821ce/
   • sudo apt install bc module-assistant build-essential dkms
   • sudo m-a prepare
   • sudo ./dkms-install.sh

一切似乎都安装并成功执行。然后，我重新启动了我的笔记本电脑并确保禁用了安全启动。但是，Ubuntu 仍然显示：

No Wi-Fi Adapter Found - make sure you have a Wi-Fi adapter plugged in and turned on

命令uname -r返回：

5.4.0-7634-generic

命令sudo lshw -C network返回：

我究竟做错了什么？如何解决？
