我刚买了一台华硕 tuf gaming a15，想安装 ubuntu 18.04（不是 20.04，因为 tensorrt 等一些程序还不支持）。我使用可启动的 usb 进行安装，安装后由于这个问题我无法启动无法在 ASUS Tuf a15（ACPI？）上安装 Ubuntu 20.04 因此，按照推荐的答案 (GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset") 我成功启动了。但随后我意识到，虽然 wifi 似乎可以工作，但它无法找到周围的任何网络。

我不认为这是适配器的问题，因为 Windows 10 似乎能很好地找到适配器。这是我第一次发现这样的问题，所以我不知道该怎么办，如果有人从未处理过这样的错误，请告诉我。
（我可以通过以太网连接到互联网，运行良好）
答案1
Ubuntu 18.04 存储库linux-firmware中不包含rtw8822c_wow_fw.bin文件。在 20.04 中已添加。
你可以通过这种方式获取它。在终端中运行：
sudo apt install git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp linux-firmware/rtw88/rtw8822c_wow_fw.bin /lib/firmware/rtw88
重新启动后 Wi-Fi 就可以正常工作了。
linux-firmware您可以根据需要删除该目录。安装固件后就不再需要它了。
