Windows 7上的上载速度慢 [英] Slow upload speeds on Windows 7

问题描述

我很沮丧.在工作中，我的配备Atheros AR8152/8158 PCI-E快速以太网控制器的Windows 7笔记本电脑的下载速度为10+ Mbps，但上传速度不到1 Mbps.

I was stumped. At work, my Windows 7 laptop with an Atheros AR8152/8158 PCI-E Fast Ethernet Controller was clocking download speeds of 10+ Mbps but upload speeds were less than 1 Mbps.

在我的有线互联网上，两个速度均为12+ Mbps.

At home on my cable internet, both speeds were 12+ Mbps.

顺便说一句，我用www.speedtest.com来测试我的速度.

BTW, I used www.speedtest.com to test my speeds.

推荐答案

答案是我的NIC上的大型发送卸载(IPv4)设置.默认情况下已启用.当我禁用它时，我的工作上传速度跃升至12+ Mbps.看来，如果基础结构(例如路由器，交换机)不支持此选项，则传输会变得突发"并变慢.我的家用路由器(Apple Airport Extreme)显然支持此选项.

The answer turned out to be the Large Send Offload (IPv4) setting on my NIC. It was enabled by default. When I disabled it my work upload speed jumped to 12+ Mbps. It appears that if the infrastructure (e.g. routers, switches) don't support this option the transmits become "bursty" and slow down. My home router (an Apple Airport Extreme) apparently does support this option.

要禁用，请转到开始"->控制面板"->设备管理器"->网络适配器"->"Atheros AR8152/8158 PCI-E快速以太网控制器(NDIS 6.20)"，右键单击，然后选择属性".在高级"选项卡上，找到属性大型发送卸载(IPv4)"并将其值更改为 Enabled ，然后单击确定".

To disable, go to Start->Control Panel->Device Manager->Network adapters->Atheros AR8152/8158 PCI-E Fast Ethernet Controller (NDIS 6.20), right-click then select Properties. On the Advance tab, find property Large Send Offload (IPv4) and change its value to Enabled then click OK.
