我的 Synology TC1900ac 出现了一个奇怪的问题。WiFi 大部分时间都运行正常，但有时所有无线连接设备都会失去连接。它们似乎仍有连接，但甚至ping 192.168.1.1会失败。新设备根本无法连接到 Wifi。
我在 Web 界面中找不到任何错误消息。有时，禁用并重新启用 Wifi 可以解决问题。
幸运的是，Synology 通过 SSH 提供了 root 访问权限，因此我能够查看设备上的日志。以下是我发现的可能相关的内容：

我尝试找出TX Deauth pkt可能的原因，但却找不到能提供清晰解释的资源。
我怎样才能找出问题所在？
答案1
这个日志没有任何问题，Synology 路由器的最新固件中有一个错误（RT1900ac 和 RT2600ac 都受到影响）。
