新买的小欧24一体机无线网络慢

[漫步云端]

今天新买的小欧24I9100的无线网卡RTL8821CE，；连接200M电信网络时状态显示速率只有57M。在网页上测试只有40多，有线测试2百多，请问有什么办法解决？（微信咨询过说是单天线AC，实测只有双天线的一半，这是正常值）

只能换无线网卡

RTL8821CE 官方数据是 1T1R

Eight-antenna AP, four 2-antenna STAs, 160 MHz (MU-MIMO)	Digital TV, tablet, laptop, PC	1.69 Gbit/s to each STA	6.77 Gbit/s

80MHz 时，是 433 Mbit/s，除以8，就是 54.125‬MB/s

160 MHz 现在基本上没有路由器可以支持，当然以后会有支持的路由器。

1天线相当于单车道，2天线相当于2车道。理论上确实，相对只有一半速度。
