概述
事件起因是:电信说可以免费提速至200M,我就把自家的宽带从100提到了200。但网速测试发现仍是100M没有变化。
然后就想着用iperf3 测一下内网速度,看看有没有线索。
结果大跌眼镜。5G比2.4还要慢。5G带宽:254Mb; 2.4G带宽:437Mb.
请教大神:这是几个意思?
测试环境:
1.PC和手机(iphone-8P) 都在同一副路由(AC66U B1)下面。主路由AC1900P 进行拨号,光猫桥接。
2.手机下载WiFiPerf Endpoint,作为iperf3的服务器端。(不知道是不是因为防火墙的原因,PC作服务器端,手机上的iperf 就是连不上。只能反过来用。)
测试结果:
