每隔几分钟,我的 Lenovo Yoga X1 20FR 笔记本电脑的 Wi-Fi 接口就会出现暂时中断。以下命令的输出记录了ping一次此类事件。每秒都会添加一行新内容,以便您可以看到问题通常持续多长时间。

ping 192.168.1.1 -t  (this is a router to which the laptop is connected)

故障每 10 分钟重复发生一次。在事件日志系统中,可以看到以下两条消息:

• Name resolution for the name _ldap._tcp.Site-AAAA-RA._sites.dc._msdcs.AAAA.com. timed out after none of the configured DNS servers responded.  (AAAA-real name masked)
• NtpClient was unable to set a domain peer to use as a time source because of discovery error. NtpClient will try again in 15 minutes and double the reattempt interval thereafter. The error was: The entry is not found. (0x800706E1)

在我看来,好像有什么东西正在“玩”Wi-Fi 网络适配器,而上述两条消息只是其重新初始化的结果。

是什么原因造成的?如何解决?

答案1

定期的失败安排让我检查任务计划程序,在这种情况下,它的一项任务(自定义任务)是罪魁祸首。

这似乎是我雇主的 IT 安装的一些 PowerShell 脚本。我在任务计划程序中发现了一个任务上次运行时间总是与最近一次故障的时间相对应。我现在只是调整一下,但一般来说,这是向 IT 部门提出问题的时候了。

更新:后来我还发现,当 DNS 租赁期的一半到期,因此有时间续订租赁时,也会导致类似的行为。例如,如果路由器上的 DNS 租赁期设置为 20 分钟,则每 10 分钟就会发生一次此问题。我将租赁期延长至 3 天以缓解此问题。
