WiFi 无法使用。不知道如何修复。我的旧电脑上有同样的 WiFi 芯片，通过禁用快速启动可以正常工作。我确实禁用了快速启动，但没有成功。我已经更新了。
如何修复？
一些命令和输出：

在终端中：
sudo lshw -class network
英特尔 AX210 Wi-Fi 卡自更新至 1.196 后无法工作
将文件 iwlwifi-ty-a0-gf-a0.pnvm 重命名为 iwlwifi-ty-a0-gf-a0.pnvm.old
在终端中：
sudo mv /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm.old
