这应该是country code不对
WLC: show country
AP: show inventory
(wireless-vwlc-2) >
(wireless-vwlc-2) >config 802.11a disable network
Disabling the 802.11a network may strand mesh APs. Are you sure you want to continue? (y/n)y
802.11a network is already disabled.
(wireless-vwlc-2) >config 802.11b disable network
Disabling 802.11b network may strand mesh APs. Are you sure you want to continue? (y/n)y
802.11b network is already disabled.
(wireless-vwlc-2) >
(wireless-vwlc-2) >config country ?
Enter the country code list (e.g. US,CA,MX) max per command = 30.
(wireless-vwlc-2) >config country CN,US          << 这里需要改成和AP对应的国家码
Changing country code could reset channel & RRM grouping configuration.
If running in RRM One-Time mode, reassign channels after this command.
Check customized APs for valid channel values after this command.
Are you sure you want to continue? (y/n) y
另外可以顺便看一下License
(wireless-vwlc-2) >show license summary

WLC 的日志也导出来看看,检查国家代码、检查WLC AP版本是否兼容,检查时间是否正常

WLC在初始化配置的时候会有国家代码一般给中国的都是CN,然后是AP的型号-C代表的就是中国,-X代表不通的国家,型号要和初始化时候的国家代码对应,否则AP会注册失败

请问a代表的是美国吗?
