reason codes, CWAP, Deauthentication, Reason Codes Deauthentication Frame Station or AP can send a Deauthentication Frame when all communications are terminated (When disassociated, still a station can be authenticated to the cell). Deauthentication frame format is as
shown below. It is subtype 12 (0x0c) management frame (type 0) & you can filter client disassociated reason code 8 it using below wireshark filter. (wlan.fc.type == 0)&&(wlan.fc.type_subtype == 0x0c) Frame body of Deauth frame contains following 1. Reason Code (2 byte) 2. class 2 frame received from non authenticated station Vendor Specific Information (one or more) 3. 802.11w (MFP) info Here is a capture of a Deauthentication frame. In this case client station specify reason code as 3 - Deauthenticated because sending station is leaving BSS.Once AP https://supportforums.cisco.com/document/141136/80211-association-status-80211-deauth-reason-codes receive this, it should send ACK to the client station. Here is another deauthentication frame, where in this instance reason code 4 - Disassoicated due to Inactivity. In the below case due to 1- Unspecified reason client has been deauthenticated.Here is another Deauth frame captured. This is triggered when I enable client management frame protection on a SSID. This time AP sending deauth to client with reason code 6 - Class 2 frame received from https://mrncciew.com/2014/10/11/802-11-mgmt-deauth-disassociation-frames/ nonauthenticated station. Here is the complete list of Reason Codes as per IEEE 802.11-2012 standard.(table 8.36) Disassociation Frame Once a station associated to an AP, either side can terminate the association at any time by sending a disassociation frame. It has the same frame format as deauthentication frame. A station can send a disassociation frame because it leave the current cell to roam to another cell. An AP could send disassociation frame because station try to use invalid parameters.(above given reason codes applicable to disassociation frames as well). You can filter disassociation frames in wireshark using below filter (subtype 10 management frames) (wlan.fc.type == 0)&&(wlan.fc.type_subtype == 0x0a) Disassociation frame's destination address could be a Unicast MAC address or Broadcast Address. If a single station to be disassociated it can be send to client unicast MAC address. If all stations needs to be disassociated, disassociation frame can be send to broadcast MAC address. Here is a disassociation frame send by a client station with reason code 8 - Disassociated becaues sending station is leaving. Here is another disassociation frame sent by AP to client station. (This is triggered when I shut down the WLAN from controller). In this case reason code 1- Unspecified Reason.

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.

Reimage also restores compromised system settings and registry values to their default Microsoft settings. You may always return your system to its pre-repair condition.
