AP 无法加入到WLC

[yujun]

之前WLC 2504和AP在另外一个办公室正常使用的，因为办公室搬迁，将AP 和WLC 迁移到另外一个办公室，AP和WLC连接后，登录WLC发现没有一个AP加入，AP指示灯红色橙色和蓝色交叉闪烁。
用控制线登录AP 提示以下信息：

已经解决了，是因为WLC断电后时间被恢复到2000年的缘故，重新手动设置时间，AP重新上线了。

已解决了，是时间问题。

谢谢楼主分享，今天刚好也碰到这个问题，修改了WLC时间，问题解决了:lol

现在又有个问题，显示AP已经加入到WLC，WLC上面也可以看到加入成功，但是AP指示灯还是红-绿-蓝，而且也没有广播SSID
