Scan, monitor, and troubleshoot wireless networks with WiFi Explorer.

Quickly identify channel conflicts, signal overlapping or configuration problems that may be affecting the connectivity and performance of your home, office or enterprise wireless network.

Get an insight into the network details: name (SSID), MAC address (BSSID), device manufacturer, signal strength (RSSI), noise, channel, band, security configuration, supported data rates, 802.11 information elements (IE), and much more.

• Suitable for home, small office, or enterprise networks
• Easy-to-use, intuitive user interface
• Graphical visualization of the Wi-Fi environment
• Supports 2.4 GHz and 5 GHz frequency bands as well as 20, 40, 80 and 160 MHz channels
• Works with 802.11a/b/g/n/ac networks


• Comprehensive app's help
• Signal quality ratings based on signal-to-noise ratio (SNR)
• Accurate conversion from dBm to percentage (%) for easier analysis and optimization
• Detailed description of information elements (IE) advertised by the access point for advanced troubleshooting
• Export metrics and network details to CSV file format
• Save results for later review and analysis
• Access point name discovery (if supported)
• Editable column for labels or annotations
• Selectable and sortable columns
• Adjustable graph timescales
• Quick filtering
• Customizable colors for easily tracking particular networks

Beautiful, full of information, but there’s a problem


Please label your left axes. Percent of what? This is a common problem in the sciences, too. /Always label your axes/. I can see where there is a problem, but if I showed it to someone else I imagine their reaction would be, “Pretty. You’re my favorite nerd, and I have no idea what this means.” However, it is great, so five stars.
Feature suggestion: Interface with popular routers and use this information to automatically optimize. If the major companies won’t give you an API, offer suggestions for tuning.

Developer Response

Hi caburlingame, I fully agree that labels are important, however, labels are not being used to save space. It is understood the app is showing signal levels, which are measured in decibels relative to 1 milliwatt (dBm). Nevertheless, to simplify the user's perception of how strong the signal is, the app also offers, by default, the option to display the signal level as percentage (see WiFi Explorer > Preferences > General). Thus, for example, 100% corresponds to full signal strength, 50% to half signal strength, and so on. Conversion from dBm to % is not linear (e.g. -50 dBm != 50%) and assumes certain max and min values for scaling. You can find more details on how the conversion is done in this blog post:

Useful, Attractive Tool, Well-Maintained!


I am a netwrk technician, and I use this software often in my work. The feature set is solid, I use the graphs to help my customers understand their networks, and the author looks after his product with regular updates and feature-adds. Customers are impressed by this software too. If you think this software might be useful to you, I say go for it.

Go-to for interference


This is always the first app I launch whenever I get complaints of “wifi problems,” and 99% of time time I’m able to immediately identify nearby rogue access points that are screaming over my channels. It’s also amazing for wifi planning and optimisation. I end up running this app on at least a weekly basis, sometimes more.
