1、STA正常接入

actives in BSSID(0a1b.b120.6fa1): Assoc
succeed. |
关联成功 |
|
说明：STA的无线接入过程包括Auth
和Assoc两个过程，Assoc 成功后STA才算成功接入无线网络(802.11链路接入). 后续根据实际的网络应用还有可能需要进行认证等操作，最终才能真正地访问无线网络资源。 |

reason code(3). |
四次握手失败，解关联 |
|
说明：AP配置WPA2 PSK加密，STA使用错误的密钥连接，认证成功，关联成功，然后四次握手失败，解关联。因为有的网卡会发两个认证请求报文，所有会有两次认证成功。 |
|
3、STA主动断开

STA主动解关联或解认证 |
|
说明：STA主动断开是指用户主动断开网卡连接，用户断开连接时，有的网卡会发主动断开会发解认证帧，有的网卡会发解关联帧。有的网卡甚至都解认证帧和解关联帧都不发。另一个可能原因是STA未收到AP响应的auth
resp 或assoc resp报文。 |

重关联成功 |
|
说明：STA漫游是指终端从AP1漫游到另一个同SSID但是信号强度更强的AP2上。STA关联AP2的过程称为重关联。当漫游成功时，漫入AP会显示认证成功和重关联成功。 |

|
日志 |
解读 |
|

fails to active in BSSID(061b.b18e.37f4): Data from unknown station. |
目前认为是芯片无法过滤掉所有无用报文，在一些上网本上也发现部分STA也会收到不是发给他的报文。 |
|
说明： 收上来后也会马上丢弃，不会有其他负面影响 |
|
14.关联或重关联报文WPA IE 信息错误
|
日志 |
解读 |
|
"%WLAN-6-80211N: STA(7c61.9337.f036) fails to

日志 |
解读 |
|
STA(4c0f.6e8c.6e8d) leaves BSSID(0a1b.b120.0c23):
STA deauth, reason code(4) |

16、Beacon帧主信道与工作信道不一致
|
日志 |
解读 |
|
不一致点: Work channel
is 6, primary channel is 2 |
Beacon帧主信道和工作信道不一致时，提示信息。 |
|
说明：不一致点：在不同阶段打印不同的值。 WLAN-6- BEACON_INIT: beacon初始化时主信道和工作信道不一致； WLAN-6- BEACON_UPT_CHECK1: 更新beacon时主信道和工作信道不一致,这个地方会将工作信道赋值给主信道； WLAN-6- BEACON_UPT: 更新beacon开始时主信道和工作信道不一致提示，此时信道会被修订； WLAN-6- BEACON_UPT_CHECK: 更新beacon结束时主信道和工作信道不一致提示，此时信道会被修订； WLAN-6- PRIMAR_CHECK: beacon入DMA前主信道和工作信道不一致提示，此时信道不会被修订； |

17、接收到STA
ps poll帧，打印关联ID为空日志。
|
日志 |
解读 |
|
STA(7c61.93ec.aab7) is
forced to leave BSSID(061b.b122.5687): Client has NULL AID, reason code(7). |
接收到STA ps poll帧，打印关联ID为空。 |
|
说明： 由于环境原因， STA没有收到AP发的解关联帧，导致STA以为自己还在线，并向AP发送ps poll帧，而AP接收到这个帧时，找不到该STA的信息，所以会打印该日志。该日志只是正常的一个提示，不影响用户体验。 |
