There are plenty of potential uses for this utility and the wireless stumbler, whether it’s optimizing networks, reducing interference and noise, or discovering those around you, but the wifi diagnostics app also includes many powerful features that allow you to capture network traffic, be it data that is sent from the computer in use or even all nearby wireless networks. The tool defaults to scanning once and displaying the found information, but you can turn on Active Scan or Passive Scan mode to constantly search for new networks by clicking on the “Scan” pulldown menu in the lower right corner. Under the Wi-Fi Scan tool, you will see all available network names and their respective BSSID, channel, band, protocol (wireless n, g, b, etc), security type, their signal strength, and the noise level of the signal. Select “Wi-Fi Scan” tab to summon the scanner and stumbler wireless networking tool.Open Wireless Diagnostics and ignore the menu, instead pull down the “Window” menu and select “Utilities”.If the app is called “Wireless Diagnostics”, to access the scanning utility is slightly different: Click the “Wi-Fi Scan” tab to get started with the wireless stumbler tool.Launch Wi-Fi Diagnostics and ignore the frontmost menu, instead hit Command+N to summon the new “Network Utilities” window (this is also where the wireless signal strength measurement tool is located now).If the app is called “Wi-Fi Diagnostics”, here is what you need to do: Outside of accessing the tool, all functionality remains the same.

This will open the wireless card to detect all possible nearby wifi networks, effectively stumbling onto available wireless routers and discovering details about those networks.Īll available wireless network names, SSID, channels, band, network protocol (wireless n, g, b, etc), the network security type, the network signal strength, and the network noise level of the signal discovered will be listed by the scan utility. Within the Scanner tool, click on the Scan button to scan for available networks.
