最近安装了openEuler24.03,但是开机以后没有无线网卡的驱动，但是好在github上有个项目提供了rtl89代码的存储库，包含了以下网卡的驱动程序：Realtek 8851BE, 8852AE, 8852BE, 8852CE, and 8922AE。

安装前需要安装 “make”、“gcc”、“kernel headers”、“kernel build essentials” 和 “git”。

git clone https://github.com/lwfinger/rtw89.git
cd rtw89
make
sudo make sign-install

但是安装好后重启发现还是没有无线网卡选项，使用dmesg | grep firmware 查看内核缓冲区是否有报错信息：

[sea@localhost ] sudo dmesg | grep firmware

发现缺少rtw89/rtw8852a_fw.bin文件，直接去另一个系统的/lib/firmware/rtw89目录下复制一份过来，然后：

sudo chmod 644 /lib/firmware/rtw89/rtw8852a_fw.bin
sudo modprobe -r rtw_8852ae
sudo modprobe rtw_8852ae

然后重启解决。
