最近我遇到了一个奇怪的问题。每隔约 15 分钟左右，我就会与家庭 wifi 网络断开连接。最奇怪的是，要解决这个问题，我只需单击“连接”，然后我就会重新连接。我试过多个无线网卡，它们都有这个问题。有什么想法吗？
编辑：我复制了 /var/log/syslog 三次 - 一次是在我被踢出之前，一次是在我被踢出之后，一次是在我重新连接之后。
在我被踢出之前，有一些有趣的消息......

另外，我将所有网络名称改为“Noon 的网络”，但这个“Noon 的网络 1”并不是我审查的产物——到处看到的“Noon 的网络 1”，原文都是 [真实网络名称] 1。（此外，真实网络名称有一个撇号。）
我不知道那是怎么回事。
