Code Reason
0 Reserved
1 Unspecific Reason
2 Previous authentication no longer valid
3 Deauthenticated because sending STA is leaving (or has left) IBSS or ESS
4 Disassociated due to inactivity
5 Disassociated because AP is unable to handle all currently associated STAs
6 Class 2 frame received from nonauthenticated STA
7 Class 3 frame received from nonassociated STA
8 Disassociated because sending STA is leaving (or has left) BSS
9 STA requesting (re)association is not authenticated with responding STA
10 Disassociated because the information in the Power Capability element is unacceptable
11 Disassociated because the information in the Supported Channels element is unacceptable
12 Reserved
13 Invalid information element.
14 Message integrity code (MIC) failure
15 4-Way Handshake timeout
16 Group Key Handshake timeout
17 Information element in 4-Way Handshake different from (Re)Association Request/Probe Response/Beacon frame
18 Invalid group cipher or Association denied due to requesting STA not supporting all of the data rates in the BSSBasicRateSet parameter
19 Invalid pairwise cipher
20 Invalid AKMP
21 Unsupported RSN information element version
22 Invalid RSN information element capabilities
23 IEEE 802.1X authentication failed
24 Cipher suite rejected because of the security policy
25-31 Reserved
32 Disassociated for unspecified, QoS-related reason
33 Disassociated because QoS AP lacks sufficient bandwidth for this QoS STA
34 Disassociated because excessive number of frames need to be acknowledged, but are not acknowledged due to AP transmissions and/or poor channel conditions
35 Disassociated because STA is transmitting outside the limits of its TXOPs
36 Requested from peer STA as the STA is leaving the BSS (or resetting)
37 Requested from peer STA as it does not want to use the mechanism
38 Requested from peer STA as the STA received frames using the mechanism for which a setup is required
39 Requested from peer STA due to timeout
45 Peer STA does not support the requested cipher suite
45-65 Reserved
535 Reserved
