为什么长 HTTP 请求会被切断？

我的下载速度为 768 Kbps，各种速度测试网站都说我实际的速度约为 400 Kbps，这已经足够了。Windows Wifi 质量指示器也显示“非常好”。

但这项互联网服务无法使用。连接速度超慢。网页加载中途挂起，文件下载随时可能挂起：浏览器显示下载正在进行，但进度却停止了。

该问题出现在多台计算机上，因此问题不在客户端上。

路由器是SpeedStream 4100。连接都是无线的。

答案1

造成这种情况的原因有很多，很难知道从哪儿开始。

您的系统以前能正常工作吗？如果能，您知道有什么变化吗？

其中一些原因是

Faulty router.
Interference from another Wireless router.
Too much noise on the telephone line (from within your house)
Problem with the telephone line (outside you).
Problem with your internet provider. 
Bandwidth being used up. 
Problems caused by virus.

建议（无特定顺序）

Switch off the router for a while (Maybe even overnight).
If possible, try connecting via a cable rather than wirelessly.
Ask your ISP to investigate your line quality. 
Temporarily disconnect all other equipment from your telephone line.
Connect your modem to the master telephone socket.
Move your router away from another other electrical cables/equipment
Scan for virus/spyware
Your wireless router should have an option to change channels which 
     can help avoid interference from other people's equipment.
Try a different browser.
If you have access to a good internet connection, download and burn a
   Linux LiveCD which you can boot off.
Try another router.
Check your wireless security to make sure no-one is hijacking your line.

这可能是 QoS（服务质量）问题：路由器或提供商决定应为长请求赋予较低优先级。如果您调整了路由器设置，请检查是否没有弄乱任何东西。如果此方法无效，我建议您联系提供商。
