我最近升级到了 3G 无线数据连接。我的互联网连接问题是，在访问某个网站几次后，服务器停止响应。后来我在 chrome 上以隐身模式或在 Firefox 上以隐私浏览模式打开该网站，一切正常。即使我只是清除浏览器 cookie/缓存，网站也会开始响应。即使重新启动浏览器，网站也会开始正常响应。我经常访问的几乎所有网站都至少发生过一次这种情况。
由于某种原因，我将操作系统从 fedora 更改为 debian，但即使如此，问题仍然存在。
从技术上讲，我不知道为什么会发生这种情况。有人可以帮忙吗？
更新：

答案1
您的症状听起来像是缓存问题。您使用的是卡还是无线绑定到手机？要么是您的提供商的缓存服务器运行不佳，要么是 LAN 中的其他设备（调制解调器、路由器或防火墙）出现问题。（您有这样的设备吗？如果有，请移除它们，看看问题是否消失。还可以尝试连接到另一个网络，看看问题是否仍然存在；如果问题仍然存在，则问题出在您的机器上，与您的连接无关。）
但是，如果您确定问题出在您的提供商身上，并且您的网络中没有其他设备，请致电技术支持并告诉他们您在缓存服务器方面遇到了问题；他们可能会为您提供解决方案。
