我尝试以 300Mbps 的速度连接到我的新路由器。我的新无线路由器在 2.4Mhz 下可接受 300Mbps，在 5Mhz 下可接受 450Mbps。我在路由器旁边测试，最高速度为 150Mbps。
我很清楚 150/300/450Mbps 在现实生活中意味着什么，但问题是，连接到 150Mbps 不会在网络传输文件时产生超过 8MBps 的任何效果。
我在 Windows 7 中进行了同样的测试，我可以获得 300Mbps 的链接（波动，但在这个速度下非常稳定），文件传输速度为 22MBps。
我能做些什么吗？谢谢！

答案1
IPS 经常会给你带来麻烦，我猜你把 8MB 放在了大写字母“乙“ 故意地？
兆比特 (megaBITS) 和兆字节 (megaBYTES) 之间是有区别的，你的 ISP 会说你将获得 150Mb/s 的连接速度，大约是 10+/- MB/s（兆字节）
