![突然无法访问互联网 - Windows 10](https://linux22.com/image/1585404/%E7%AA%81%E7%84%B6%E6%97%A0%E6%B3%95%E8%AE%BF%E9%97%AE%E4%BA%92%E8%81%94%E7%BD%91%20-%20Windows%2010.png)
我花了一天中的大部分时间来审查这里报告的类似问题,但遗憾的是,我无法确定任何与此案例中的独特方面相对应的问题。
问题:
在应用 Windows 更新 KB4486553(可能与此有关,也可能无关)并重新启动后,PC 通过以太网连接和 USB Wi-Fi 连接丢失了所有互联网连接。网络上的所有其他设备(包括另一台同样更新的 X99 Windows 10 PC)均不受影响。
不同寻常的是,这也许只是因为 PC 是一台旧的 X58(华硕 P6T7 主板),因此启动缓慢,每次重新启动时,互联网最初都是连接的(Google 页面、Outlook 2016、TeamViewer 连接、WhatsApp 访问、OneDrive、Dropbox 等都证明了这一点)。然而,在几分钟内(启动顺序期间),所有连接都丢失了。但是,网络设置“状态”继续报告“您已连接到互联网”(虽然显然没有),任务栏(或其他地方)上没有显示任何警告三角形。
故障排除步骤(据我记忆所及,已尝试过):
- 卸载问题发生前的 Windows 更新
- 重新启动电脑(多次)
- 重新启动路由器(多次)
- 交换两条以太网线(已知良好的)
- Wi-Fi 网络报告(图表显示连接/断开连接)
- Ping(网关 IP)– 始终成功
- Ping(互联网)——总是失败(公平地说,当我能够 Ping 时,连接总是断开了)
- 运行网络疑难解答(Windows 无法自动检测此网络的代理设置)
- 重置 TCP/IP 堆栈 (
netsh winsock reset
/netsh int ip reset
) - 释放/续订 IP 地址 (
ipconfig /renew & ipconfig /renew
) - 刷新并重置 DNS 客户端解析器缓存 (
ipconfig /flushdns
) - 卸载、更换并随后(作为进一步的步骤)更新网络适配器驱动程序至最新发布的
- 禁用(用于测试)防病毒和防火墙软件
- 尝试将系统还原到三个单独的最近还原点(由于防病毒软件在还原尝试之前已被禁用,因此所有还原均失败)
- 在 Windows 10 设置中执行网络重置
- 重新启动至带网络连接的安全模式,并选择性启动(
msconfig
)以进行诊断 - 将网络设置与正常运行的 Windows 10 计算机进行比较,以查找异常
- 审查事件查看器日志(应用程序和服务日志)
- Microsoft/Windows/通用遥测客户端
Event 55 Reports: "Is the Internet available:true"
Error 29 Reports: "Connection state - Some connections have failed since the previous period."
尚未尝试(因为可能会丢失为方便使用而应用的大范围复杂菜单调整)
- 就地系统修复安装
尽管应用了上述故障排除步骤,上述情况仍在所有场景中继续发生,通常是多次和以各种组合发生。
因此,我欢迎任何关于我还可以尝试什么以及如何解决这个问题的想法。

快速更新解决方案,希望它能帮助其他遇到同样问题的人。终于找到了原因。
尽管 Q 中描述了 10 天内采取了无数的故障排除步骤,包括从“安全模式”开始并禁用启动项,但奇怪的是,罪魁祸首竟然是 IPVanish VPN Windows 应用程序(我只能推测在 Windows 更新重启期间经历了某种形式的损坏)和一个名为“终止开关”的复选框设置,该设置被发现在应用程序深处被神秘地启用。
IPVanish 始终配置为随“Windows”启动,但处于 VPN 断开状态。看来 IPVanish 深深嵌入启动序列中。它被设置为断开启动(因为在使用 Outlook 时连接到 VPN 时无法访问电子邮件服务器,而 Outlook 本身设置为随 Windows 10 自动启动,因此会在后台收集我的电子邮件)这一事实触发了(现已启用的)终止开关提供的保护。
IPVanish 提供了以下有关“Kill Switch”的有用摘要:
什么是 Kill Switch?如果/当您当前的 VPN 连接停止工作时,Kill Switch 会关闭所有互联网流量。如果您想最大限度地保护您的隐私和匿名性,这是一个很棒的功能,因为如果您没有受到 VPN 的保护,Kill Switch 会切断您的互联网。这意味着即使与我们的 VPN 的连接断开,您的隐私仍然是安全的。
IPVanish 继续发表了以下有趣的评论:
如果您在连接互联网时遇到任何问题,请仔细检查以确保 Kill Switch 尚未启用。
