Description
WifiInfoView scans the wireless networks in your area and displays extensive information about them, including:
Network Name (SSID), MAC Address, PHY Type (802.11g or 802.11n), RSSI, Signal Quality, Frequency, Channel Number, Maximum Speed, Company Name,
Router Model and Router Name (Only for routers that provides this information), and more...
When you select a wireless network in the upper pane of this tool, the lower pane displays the Wi-Fi information elements
received from this device, in hexadecimal format.
WifiInfoView also has a summary mode, which displays a summary of all detected wireless networks, grouped by
channel number, company that manufactured the router, PHY type, or the maximum speed.
Wifi Access Points Viewer
System Requirements
- Operating System: This utility works on Windows Vista, Windows 7, Windows 8, Windows Server 2008, Windows 10, and Windows 11.
Both 32-bit and x64 systems are supported.
Windows XP is not supported because this tool is based on new Wi-Fi API that doesn't exist on Windows XP.
If you want to get wireless networks information on Windows XP, you can use the WirelessNetView utility.
- Wireless network adapter and wireless card driver that works with the built-in wireless support of Windows Vista/7/8/2008.
If you don't have a compatible wireless adapter and driver, "cannot find wireless adapter" error will be displayed.
- In order to watch 5GHz wireless networks, you have to use a wireless network adapter that supports 5 GHz channels.
- Windows 11 24H2 Update - Starting from this Windows update, you must enable location access (Windows Settings> Privacy & security> Location) in order to allow the WifiInfoView tool
to access wi-fi information. You have to enable the following options: 'Location services', 'Let apps access your location', 'Let desktop apps access your location'.
If location access is not enabled properly, you'll see 'Error 5: Access is denied' message in the bottom status bar.

Start Using WifiInfoView
WifiInfoView doesn't require any installation process or additional dll files. In order to start using it,
simply run the executable file - WifiInfoView.exe
After you run WifiInfoView, the list of detected wireless networks in your area is displayed on the upper pane and it's updated at
very high rate. You can change update rate from Options->Update Rate menu.
When you select one or more wireless networks in the upper pane, the lower pane displays the Wi-Fi information elements
of the selected items, in hexadecimal format.
Columns In the Upper Pane
- SSID: The name of the network.
- MAC Address: MAC address of the router.
- PHY Type: The PHY type for this network - 802.11a, 802.11g, 802.11n, or High-Rate DSSS
- RSSI: The received signal strength indicator value, in units of decibels referenced to 1.0 milliwatts (dBm), as detected by the wireless LAN interface driver for the AP or peer station.
- Signal Quality: A number between 0 and 100 that represents the quality of the signal.
- Frequency: The channel center frequency of the band on which the 802.11 Beacon or Probe Response frame was received. The value of this column is in units of Gigahertz (GHz).
- Channel: Channel number used by this wireless network.
- Information Size:The total size (in bytes) of all Wi-Fi information elements received from this wireless network.
- Elements Count: The total number of Wi-Fi information elements received from this wireless network.
- Company: The company that manufactured the router, according to the 3 first bytes of the MAC address.
- Router Model: The model of the router. This value is displayed only for routers that provide this information inside the Wi-Fi information elements.
- Router Name: The name of the router. This value is displayed only for routers that provide this information inside the Wi-Fi information elements.
- Security: Specifies whether the network is secured (Yes/No).
- Maximum Speed: The maximum speed (in Mbps) that you can get when connecting to this wireless network.
- First Detection: The first date/time that this network was detected.
- Last Detection: The last date/time that this network was detected.
- Detection Count: The number of times that this network was detected.
Summary Modes
When you switch to one of the summary modes, instead of showing the list of all networks,
WifiInfoView only shows the number of networks and the average/minimum/maximum of the signal quality for every group.
Wifi Channels Report
For example, in the above screenshot, you can see that there are 25 wireless networks that use channel 6, 10
wireless networks that use channel 11, and so on....
In the example below, you can see the there are 9 wireless routers of NETGEAR, 8 wireless routers of Sagemcom,
and so on... (Be aware that some companies may appear more than once, with a little different name)
Wifi Companies Report
The following summary modes are available under the Options menu:
Channels Summary Mode, Companies Summary Mode, PHY Types Summary Mode, and Max Speed Summary Mode
The 'Company' Column
WifiInfoView allows you to view the company name of each wireless device.
The company name is determined according to the MAC address.
By default, WifiInfoView uses an internal database of MAC addresses/companies which is updated from time to time.
If you want to use the most updated database, you can download it from the following link, and put in the same folder
of WifiInfoView.exe:
http://standards-oui.ieee.org/oui.txt
Be aware that you must save it as 'oui.txt'
Connect Selected Access Point
The 'Connect Selected Access Point' option (F2) allows you to connect to the desired access point from the main window of WifiInfoView.
This feature is especially useful if you have multiple access points with the same name, because WifiInfoView allows you choose the access point to connect.
, as opposed to the default wifi manager of Windows, which makes the connection according to the network name.
Export to .pcap file
Starting from version 2.90, you can export the access points information to .pcap file by using the 'Export Selected Items To .pcap file' option (Ctrl+E), and then
open and analyze the generated .pcap file with the Wireshark software.
When you use this option, a single beacon frame with all information elements is added to the .pcap file for every access point that you select.
Here's an example for .pcap file generated by WifiInfoView, and then opened in Wireshark:
Using WifiInfoView With GetNir Tool
You can use WifiInfoView together with GetNir tool to extract specific value from WifiInfoView.
Here's some example:
- Get the RSSI of 'MyNet' access point and send it to stdout:
WifiInfoView.exe /stab "" | GetNir "RSSI" "SSID=MyNet"
- Get the RSSI of access point that its BSSID is 01-02-03-04-05-06 and store it in rssi.txt :
WifiInfoView.exe /stab "" | GetNir "RSSI" "MACAddress=01-02-03-04-05-06"> rssi.txt
- Get the list of access points on channel 48, and send the result to stdout:
WifiInfoView.exe /stab "" | GetNir "SSID" "Channel=48"
- Get the name, BSSID, and RSSI of the access point you are connected to, and send the result to stdout:
WifiInfoView.exe /stab "" | GetNir "SSID,MACAddress,RSSI" "Connected=Yes"
