在无线接入点 (Netgear WAX218 - AX3600 WiFi 6 双频 PoE+) 和 Ubuntu (2022.10) 系统断网近三个月后，Ubuntu 不再能够连接到网络。相反，它会自动连接到接入点的配置 wifi。只需切换到配置的网络即可触发错误通知，内容如下：
Connection failed
Activation of network connection failed
奇怪的是：
接入点的 wifi 网络仍可与网络上的所有其他设备配合使用。只有 Ubuntu 盒子有问题。将Ubuntu 盒子连接到另一个网络（例如移动热点）也可以正常工作，因此这不是 wifi 适配器的故障，而是接入点和 Ubuntu 之间的问题。
Ubuntu 盒子用于设置接入点的 wifi 网络，这很可能是它自动连接到接入点的配置 wifi 的原因。
现在的问题是，如何在不重置接入点的情况下解决这个问题？如果你有什么想法，请分享。
除此之外，以下是两次连接尝试之间记录到系统日志中的内容：
