我有一台联想 P14s Gen2。我有 Windows 10 和 Ubuntu 20.04 LTS 双启动。在过去的几周里，我只使用了 Ubuntu，所以很长时间没有在 Windows 中启动了。
直到今天，我都能够使用以太网电缆和 wifi 适配器连接到互联网。但是，今天早上我遇到了“未找到 Wifi 适配器”的错误。
首先，我尝试禁用 Windows 中的快速启动，但没有帮助。
然后，我尝试使用 再次在 Ubuntu 中加载驱动程序
sudo modeprobe -r iwlwifi，但sudo modeprobe iwlwifi仍然没有任何区别。接下来，我按照这里的说明进行操作使用 Ubuntu ISO 安装驱动程序。此操作没有成功，因为将 ISO 安装为 CDRom 后，它未被检测为附加驱动程序。
似乎在启动时出现错误。以下是之后的错误消息sudo dmesg | grep iwl：

[ 3.963756] iwlwifi 0000:09:00.0: Failed to run INIT ucode: -110
- 我也尝试过更新内核。但还是没什么改善。
它似乎试图加载三个 不存在的.ucode 模块iwlwifi-ty-a0-gf-a0-60.ucode，iwlwifi-ty-a0-gf-a0-61.ucode并且。我只有 iwlwifi 版本 59 和 63，但没有 60、61、62。iwlwifi-ty-a0-gf-a0-62.ucode/lib/firmware
我没有什么主意，所以欢迎任何帮助。
答案1
我删除了/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm，所以系统不会Timeout waiting for PNVM load!再抛出这个错误。这个方法很有效。
答案2
我能够通过执行以下操作来亲自解决此问题：
- 运行
ip link以获取所需的接口（我的是 wlp9s0，仅供参考） - 然后运行
ip link <interface> up查看你的接口是否已启动（我的情况是关闭的） - 如果失败，则运行
ip link set dev <interface> up
在经过多次尝试后，这个问题终于解决了，希望其他人也能觉得它有用
