答案1
我注意到一些事情：
1) 看起来您正在使用无线访问，并且您使用的任何内核都会在某些时候完全禁用该接口：
kernel: wlp58s0: failed to remove key
2）然后尝试识别硬件并连接到ssid，但找不到SSID：
failed (reason 'ssid-not-found')
3) 然后就可以正常连接到接入点了。
这里可能出了什么问题？其实有几件事：
A。我们的操作系统和内核版本是什么？您是否尝试过升级到最新的内核？
b.您的无线 AP 在该时间段内说什么？您的接入点重新启动可能会导致您的 Linux 计算机出现以下行为。
C。您是否尝试过更换无线适配器？这种情况是否发生在物理（有线）链路上？
所有日志文件中最令人担忧的错误是：
Jan 9 03:02:32 mapr04 kernel: wlp58s0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-22)
你应该注意这一点。也许尝试在这里找到答案： https://askubuntu.com/questions/967441/17-1-wlp6s0-failed-to-remove-key-1-ffffffffffff-from-hardware-22
