- 主题:搞了张8265ac无线网卡2.4G差到令人发指
就是正常的住宅楼，楼上楼下都有很多别人的wifi，自己用无线探测app查看哪些频道冲突了，重新设置一个没人用的就行了
【 在 myspam 的大作中提到: 】
: 你家周围是不是没有太多邻居2.4gWIFI互相干扰啊

2.4G跑满200M宽带，我是不太相信的。iperf测试一下实际带宽很容易。

: 我的宽带只有200M，平时下载都可以跑满

我这WIFI只要是2.4g肯定速度跑不满,也就50m左右

试了一下，小米ax6000无线路由器，两台神舟酷睿四代i7笔记本，都是7260ac无线网卡和板载千兆有线，距离路由器2米。ubuntu 20.04系统iperf3测试，2.4g确实很慢，平均速度50Mb/s。5g平均速度250Mb/s。千兆有线基本满速
