Debian Bullseye + 网络控制器:Intel Corporation Cannon Point-LP CNVi 无 wifi 接口

Debian Bullseye + 网络控制器:Intel Corporation Cannon Point-LP CNVi 无 wifi 接口

经过一些更新然后崩溃(起源故事模糊),wifi消失了。当时我使用的是 Ubuntu 20.04,但使用非自由固件彻底重新安装了 Debian。

尽管如此,问题仍然存在。我在互联网上阅读了我能找到的所有问题,但到目前为止还没有成功。所以:

  • 使用 Debian 10 干净地重新安装,然后转移到 bullseye
  • firmware-iwlwififirmware-misc-nonfree已安装
  • 所见网卡lspci: 网络控制器:Intel Corporation Cannon Point-LP CNVi
  • 无软/硬块(用 进行检查rfkill
  • ifconfig仅显示以太网和环回接口
  • dmesg | grep iwlconfig

而且我在网上找不到该版本的固件。

任何帮助,将不胜感激。非常感谢。

看起来像是一个已修复的内核错误非常最近并且可能包含在内核 5.7.8 中,简单的解决方案是使用较新的内核 (>v5.7)。
