iwlwifi：未关联且会话保护已结束

这个错误是什么意思，

未关联且会话保护已结束...

我在我的日志中得到了这个，

wlp0s20f3: Connection to AP ee:92:90:14:8a:40 lost
wlp0s20f3: aborting authentication with ee:92:90:14:8a:40 by local choice (Reason: 3=DEAUTH_LEAVING)
wlp0s20f3: authenticate with ee:92:90:14:8a:40

什么是“会话保护”？

答案1

最近我买了一个新路由器。我的笔记本电脑（Fedora 37，内核 6.3.12，intel AX200 WiFi 控制器）顺利工作了几天，然后突然失去了 wifi 连接并且无法再次重新连接（重新启动没有帮助）。我的所有其他设备都没有问题，只是我的笔记本电脑有问题。内核日志显示：

尝试启动 Windows 10，wifi 再次正常工作。所以这不是硬件问题。也尝试过在 NetworkManager 中禁用省电功能， 还是行不通。

最后我尝试在我的路由器中禁用 WPA3 身份验证，并且有效！原来是WPA2/WPA3混合模式，现在改成WPA/WPA2混合模式后，我的笔记本又可以连接了。

不知道为什么以前可以用，但今天突然失效了。我怀疑这是 iwl 驱动程序或 wpa_supplicant 的错误。
