What is the meaning of 802.11 Deauthentication Reason Codes?

Code	802.11 definition	Explanation
0	Reserved	Normal working operation
1	Unspecified reason	We don’t know what’s wrong
2	Previous authentication no longer valid	Client has associated but is not authorised.
3	station is leaving (or has left) IBSS or ESS	The access point went offline, deauthenticating the client.
4	Disassociated due to inactivity	Client session timeout exceeded.
5	Disassociated because AP is unable to handle all currently associated stations	The access point is busy, performing load balancing, for example.
6	Class 2 frame received from nonauthenticated station	Client attempted to transfer data before it was authenticated.
7	Class 3 frame received from nonassociated station	Client attempted to transfer data before it was associated.
8	Disassociated because sending station is leaving (or has left) BSS	Operating System moved the client to another access point using non-aggressive load balancing.
9	Station requesting (re)association is not authenticated with responding station	Client not authorized yet, still attempting to associate with an access poin
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	Not Used or Special Purpose
13	Invalid information element, i.e., an information element defined in this standard for
13	which the content does not meet the specifications in Clause 7
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
17	Response/Beacon frame
18	Invalid group cipher	The link speed requested by the client or AP is incompatible. (i,e. trying to operate N only speeds on a G AP)
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	Quality of Service has denied the action
33	Disassociated because QAP lacks sufficient bandwidth for this QSTA
34	Disassociated because excessive number of frames need to be acknowledged, but are not
34	acknowledged due to AP transmissions and/or poor channel conditions
35	Disassociated because QSTA is transmitting outside the limits of its TXOPs
36	Requested from peer QSTA as the QSTA is leaving the QBSS (or resetting)
37	Requested from peer QSTA as it does not want to use the mechanism
38	Requested from peer QSTA as the QSTA received frames using the mechanism for which
38	a setup is required
39	Requested from peer QSTA due to timeout
40	Peer QSTA does not support the requested cipher suite
46-65535	46--65 535 Reserved
