为什么苹果设备连不上ROS无线设备的解决方案

今天发现一个新问题，IPAD居然连不上802.11ac，我换成802.11a/n/ac模式就好了。。

Why I can't connect to MikroTik 802.11n AP with Apple Mac devices?

This problem is only seen on Mac devices based on Broadcom wireless chipsets. In order to connect with such wireless device to MikroTik 802.11n AP make sure that you don't use 'short' preamble-mode. Use 'long' or 'both' preamble-mode and Mac wireless devices will be able to connect.

苹果的设备搜到不到SSID的情况，可以用如下的方法解决。@曹总提供方法和截图
