AIR-CT2504-K9 的速度上限

问下大佬这个AC  可以支持802.11AC吗

[ilay]

是否支持802.11ac取决于WLC的软件版本，8.0.x之后的软件版本都支持802.11ac的协议，但是否能跑满ac的上限速率取决于ap的性能、连接人数、无线环境的质量，信号强度、及频宽设置等等。理想状况下是没啥问题的

再者2504总共只有4个1G接口，最大也就4G的带宽，太大的吞吐其实也撑不住

大佬，选的时候没有.11ac  。。还需要配置哪里吗

[ilay]

1.ap得支持ac

2.控制器上面WIRELESS--802.11a/n/ac里面得把ac启用起来可以

3.你截图的那个位置是无线ssid的射频选项，选择该ssid工作在哪个频段，不涉及ac的设置

谢谢大佬，发现是Channel Width 值设得太低   修改提示 failed to set channel width network must disabled to update channel width 这里的关闭网络是指关闭SSID吗

[ilay · Accepted solution]

还是相同的位置，切换到Network菜单，然后将802.11a network status 的enabled勾选去掉，apply之后就可以调整了，调整完之后再在该处重新开启即可。

大佬 ，再咨询一下，把AC 4个接口都接在3层上，需要做啥配置吗

明白了！！！再好好学习！
