- Wireless net view free download - NET TV, LaView NET, iStat wireless, and many more programs.
- For those in Windows 10 and 6, an update patch is needed and can be downloaded from the website. WirelessNetView is compatible with wireless card drivers and wireless network adaptors supported by Windows XP, Vista, and 7 with the latest Service Packs.
- After the windows 10 update, when i go to show available networks, it only has the option for airplane mode and does not have any available wi-fi networks. Ive reset the modem, ive enabled network discovery.
Overview
This is a general troubleshooting of establishing Wi-Fi connections from Windows clients.Troubleshooting Wi-Fi connections requires understanding the basic flow of the Wi-Fi autoconnect state machine. Understanding this flow makes it easier to determine the starting point in a repro scenario in which a different behavior is found.This workflow involves knowledge and use of TextAnalysisTool, an extensive text filtering tool that is useful with complex traces with numerous ETW providers such as wireless_dbg trace scenario.
Scenarios
This article applies to any scenario in which Wi-Fi connections fail to establish. The troubleshooter is developed with Windows 10 clients in focus, but also may be useful with traces as far back as Windows 7.
This troubleshooter uses examples that demonstrate a general strategy for navigating and interpreting wireless component Event Tracing for Windows (ETW). It is not meant to be representative of every wireless problem scenario.
Wireless ETW is incredibly verbose and calls out a lot of innocuous errors (rather flagged behaviors that have little or nothing to do with the problem scenario). Simply searching for or filtering on 'err', 'error', and 'fail' will seldom lead you to the root cause of a problematic Wi-Fi scenario. Instead it will flood the screen with meaningless logs that will obfuscate the context of the actual problem.
It is important to understand the different Wi-Fi components involved, their expected behaviors, and how the problem scenario deviates from those expected behaviors.The intention of this troubleshooter is to show how to find a starting point in the verbosity of wireless_dbg ETW and home in on the responsible components that are causing the connection problem.

Data Collection
- Network Capture with ETW. Enter the following at an elevated command prompt:
- Reproduce the issue.
- If there is a failure to establish connection, try to manually connect.
- If it is intermittent but easily reproducible, try to manually connect until it fails. Record the time of each connection attempt, and whether it was a success or failure.
- If the issue is intermittent but rare, netsh trace stop command needs to be triggered automatically (or at least alerted to admin quickly) to ensure trace doesn’t overwrite the repro data.
- If intermittent connection drops trigger stop command on a script (ping or test network constantly until fail, then netsh trace stop).
- Stop the trace by entering the following command:
- To convert the output file to text format:
See the example ETW capture at the bottom of this article for an example of the command output. After running these commands, you will have three files: wireless.cab, wireless.etl, and wireless.txt.
Troubleshooting
The following is a high-level view of the main wifi components in Windows.
The Windows Connection Manager (Wcmsvc) is closely associated with the UI controls (taskbar icon) to connect to various networks, including wireless networks. It accepts and processes input from the user and feeds it to the core wireless service. |
The WLAN Autoconfig Service (WlanSvc) handles the following core functions of wireless networks in windows:
|
The Media Specific Module (MSM) handles security aspects of connection being established. |
The Native WiFi stack consists of drivers and wireless APIs to interact with wireless miniports and the supporting user-mode Wlansvc. |
Third-party wireless miniport drivers interface with the upper wireless stack to provide notifications to and receive commands from Windows. |
The wifi connection state machine has the following states:
- Reset
- Ihv_Configuring
- Configuring
- Associating
- Authenticating
- Roaming
- Wait_For_Disconnected
- Disconnected
Pdf reader 1 3 2 – pdf document viewer. Standard wifi connections tend to transition between states such as:
Connecting
Reset --> Ihv_Configuring --> Configuring --> Associating --> Authenticating --> Connected
Disconnecting
Connected --> Roaming --> Wait_For_Disconnected --> Disconnected --> Reset
Filtering the ETW trace with the TextAnalysisTool (TAT) is an easy first step to determine where a failed connection setup is breaking down. A useful wifi filter file is included at the bottom of this article.
Use the FSM transition trace filter to see the connection state machine. You can see an example of this filter applied in the TAT at the bottom of this page.
The following is an example of a good connection setup:
The following is an example of a failed connection setup:
By identifying the state at which the connection fails, one can focus more specifically in the trace on logs just prior to the last known good state.
Examining [Microsoft-Windows-WLAN-AutoConfig] logs just prior to the bad state change should show evidence of error. Often, however, the error is propagated up through other wireless components.In many cases the next component of interest will be the MSM, which lies just below Wlansvc.
The important components of the MSM include:
- Security Manager (SecMgr) - handles all pre and post-connection security operations.
- Authentication Engine (AuthMgr) – Manages 802.1x auth requests
Each of these components has their own individual state machines which follow specific transitions.Enable the FSM transition, SecMgr Transition, and AuthMgr Transition filters in TextAnalysisTool for more detail.
Continuing with the example above, the combined filters look like this:
Note
In the next to last line the SecMgr transition is suddenly deactivating:
[2] 0C34.2FF0::08/28/17-13:24:29.7512788 [Microsoft-Windows-WLAN-AutoConfig]Port[13] Peer 8A:15:14:B6:25:10 SecMgr Transition DEACTIVATE (11) --> INACTIVE (1)
This transition is what eventually propagates to the main connection state machine and causes the Authenticating phase to devolve to Roaming state. As before, it makes sense to focus on tracing just prior to this SecMgr behavior to determine the reason for the deactivation.
[2] 0C34.2FF0::08/28/17-13:24:29.7512788 [Microsoft-Windows-WLAN-AutoConfig]Port[13] Peer 8A:15:14:B6:25:10 SecMgr Transition DEACTIVATE (11) --> INACTIVE (1)
This transition is what eventually propagates to the main connection state machine and causes the Authenticating phase to devolve to Roaming state. As before, it makes sense to focus on tracing just prior to this SecMgr behavior to determine the reason for the deactivation.
Enabling the Microsoft-Windows-WLAN-AutoConfig filter will show more detail leading to the DEACTIVATE transition:
The trail backwards reveals a Port Down notification:
[0] 0EF8.1174:: 08/28/17-13:24:29.705 [Microsoft-Windows-WLAN-AutoConfig]Received IHV PORT DOWN, peer 0x186472F64FD2
Port events indicate changes closer to the wireless hardware. The trail can be followed by continuing to see the origin of this indication.
Below, the MSM is the native wifi stack. These are Windows native wifi drivers which talk to the wifi miniport drivers. It is responsible for converting Wi-Fi (802.11) packets to 802.3 (Ethernet) so that TCPIP and other protocols and can use it.
Enable trace filter for [Microsoft-Windows-NWifi]:
In the trace above, we see the line:
This is followed by PHY_STATE_CHANGE and PORT_DOWN events due to a disassociate coming from the Access Point (AP), as an indication to deny the connection. This could be due to invalid credentials, connection parameters, loss of signal/roaming, and various other reasons for aborting a connection. The action here would be to examine the reason for the disassociate sent from the indicated AP MAC (8A:15:14:B6:25:10). This would be done by examining internal logging/tracing from the AP.
