移动光猫+软路由拨号DHCP+水星千兆POE交换机+ARUBA IPA 303RW

情况概述：

1，设备：移动光猫（已桥接），3205J 四口软路由【OpenWrt R21.12.1 / LuCI Master (git-21.335.48743-5f363d9)】，水星SG105P千兆POE交换机，ARUBA IPA 303RW（支持KVR无缝漫游）；
2，目前运行状态：有线一切正常，无线每隔几分钟掉线一次（表现为N1电视盒子WIFI间歇性失去连接，大概3分钟断一次，1分钟后重连）；手机不明显，但常会显示不在WIFI状态下；
3，openWRT系统日志如下：个人判断可能是几个原因：1，OPENWRT固件有问题（50%，N1电视盒子有线接入没问题，但系统日志显示eth2 link is down）；2，水星交换机有问题（10%，N1电视盒子有线接入没问题，我家云NAS有线接入没问题）；3，ARUBA 有问题（40%，已重置，但130平的房子吸顶安装，信号极差，距离1米左右偶尔信号测试显示极差）

水星交换机有线测一下，正常的话就是AP问题了

把水星交换机换成Arbua 2530-8G Poe+

Openwrt看看有无多wan服务，如有删除，如果没有类似Mwan负载均衡，换官方固件试试。

大概率在软路由的固件问题上。

ap改成固定信道
