这个问题一开始的现象是部分station无法连接某台AP。无线抓包后发现station和AP间进行了频繁的Auth认证,即station发送Auth包,ap回复Auth包出现 Expert: Wireless Authentication Denied (13: Requested authentication algorithm not supported)这样错误提示
图1所示是STA和AP频繁进行Auth认证的情况
图2所示是Expert: Wireless Authentication Denied (13: Requested authentication algorithm not supported)错误
查看kernel log,也可以发现如下的信息saaFsmRunEventRxAuth:(SAA INFO) Auth Req was rejected by [00:03:7f:12:a9:90], Status Code = 13
关于这个错误,802.11这样解释的
