我的新联想 Legion 5 Pro 16ach6 的 wifi 卡出现问题：Realtek RTL8852AE - PCIe 2.0，带有 ubuntu 20.04 和 5.12.9 内核（可在 Windows 10 上运行）。
我关注了这个主题：Realtek 8852 20.10 网络驱动程序但是 Modeprobe 找不到模块“rtw_8723de”（它不存在，我认为这是 rtw88 存储库的一个错误）并且创建的 2 .ko 不起作用：rtw89core.ko 或 rtw89pci.ko（我们可以在 lspci 中看到它）。
我尝试了不同的内核，例如 5.8、5.11、5.12，但遇到了同样的问题。Ubuntu 20.04、21.04、带有 gnome 的最后一个 Manjaro...我认为在 bios 中没问题：我禁用了安全启动和 AMD CPU 保护，但没有结果！有一个带有“独立”和“动态”图形的选项，但除了在 AMD 图形芯片组和 NVIDIA 显卡之间进行选择外，我没有发现任何区别。
当我尝试这个解决方案时：https://github.com/lwfinger/rtw89， 我有这个 ：

更新 3在 Windows 上禁用快速启动不起作用。我powercfg.exe /hibernate off曾经使用过禁用此模式（选项消失）。但我尝试启用它以取消选中快速启动选项，但这并没有改变一切。
更新 4好的，当我在 BIOS 中选中“重置为设置模式”时，我在会话开始时删除了一个错误。但没有 wifi。之后，为了安全起见，我重新安装了 Ubuntu，并继续使用内核 5.8.0.43（20.04 有 2 个内核：默认情况下 5.8.0.55 不起作用，无法启动）。
完整性：加载 X.509 证书时出现问题 -65
更新 5许多人都遇到了同样的问题（主要是在 arch 上：这并不奇怪，因为它在 Manjaro 上不起作用）。对话在这里继续（如果有有趣的消息，我会继续告诉你）：https://github.com/lwfinger/rtw89/issues/2
更新 6rtw89 的新版本在 Ubuntu 20.04 和 21.04 上运行良好。问题解决了。
答案1
构建的模块称为 rtw89pci。
LD [M] /home/user/Documents/git/rtw89/rtw89pci.ko
请尝试：
sudo modprobe rtw89pci
如果您的无线网络没有立即启动，请检查日志：
sudo dmesg | grep rtw
并发布结果。
编辑：您缺少所需的固件：
rtw89/rtw8852a_fw.bin 的直接固件加载失败，错误为 -2
除了 Jeremy 在上述评论中提出的出色方法之外，我还建议：
sudo mkdir /lib/firmware/rtw89
sudo cp ~/Documents/git/rtw89/rtw8852a_fw.bin /lib/firmware/rtw89
sudo modprobe -r rtw89pci
sudo modprobe rtw89pci
有沒有改善？
