cipher-suite ccmp 在 iOS 14 下连接WIFI非常慢

问题描述：
当配置 cipher-suite ccmp 的时候, iPhone手机连接WIFI非常慢, 下面两句日志中间足足隔了8秒. 而使用 cipher-suite tkip 连接WIFI就非常快。
这是哪里配置有误导致的么？ 目前测试只有iOS 会这样， android， macOS， windows都是很正常的。

您好，请知：
无线网络连接慢，以下是排查要点，请参考：
1、使用不加密看下是否能链接快。
2、看下DHCP地址池的IP空间范围是否足够使用。
3、调整下信道和功率看下是否能优化。
4、看下无线设备的软件版本是否最新，可考虑升级到最新。

麻烦参考如下案例进行优化：
1. 规划信道，附件有个扫描ap信道的软件，您电脑连上无线之后，可以看到当前网络中信道使用情况，2.4g信道优化选择1 6 11 2 7 12这几个信道，软件中扫描出来比较严重的信道不要使用，相邻的两个ap间信道不要一致。测试时请关闭无线扫描软件。
【举例】
# 设置射频的工作信道为6。
<sysname> system-view
[sysname] wlan ap ap3 model WA4320i-AGN
[sysname-wlan-ap-ap3] radio 1
[sysname-wlan-ap-ap3-radio-1] channel 6
2. ap之间如果间隔较近。建议修改ap射频的功率：
【举例】
# 配置射频的最大传输功率为5dBm。
<sysname> system-view
[sysname] wlan ap ap3 model WA4320i-ACN
[sysname-wlan-ap-ap3] radio 1
[sysname-wlan-ap-ap3-radio-1] max-power 17
3. 关闭RRM低速率
【举例】
# 配置802.11g模式的射频速率（禁用速率：1、2、5.5、6、9Mbps）。
[WX5540H-wlan-ap-test-radio-2]rate disabled 1 2 5.5 6 9 //AP radio视图
[WX5540H-wlan-ap-group-ceshi-ap-model-WA4320-ACN-radio-2]rate disabled 1 2 5.5 9 //AP 组 radio视图
4. 关闭广播Probe探测回应
【举例】
# 在ap1上开启AP不回应广播Probe request报文功能。（AP视图）
<Sysname> system-view
[Sysname] wlan ap ap1 model WA4320i-ACN
[Sysname-wlan-ap-ap1] broadcast-probe reply disable
