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/ax 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

Ratings and Reviews
I’ve been using this utility for years. Anyone who has been profesionally trained on wireless installations knows that it is a practiced science, not an excact science. What works for one enviornment may not work for another. What works at one location in a building may not work 50 feet away in the same building. I use this software as a systems administrator to diagnose wireless performance from my laptop as I walk around the floor in our offices. This utility makes it very quick and easy to identify performance, and see how performance fluctuates as I wander from here to there, identifying deadzones, or areas impacted by high EMI and low SNR. I’d recommend this utility. The author does a good job deploying consistent and regular bugfixes in addition to feature improvements — updating it year after year and keep this program running reliabily as Apple releases their OS X platform changes. This app is great. I’d absolutely recommend it.
BEST WiFI Scanner? Yes! Worth twice the price?! Yes!!!
I can't say enough good things about this app. NOTHING, and I mean NOTHING in this bracket does what WiFIExplorer (WE) does, or as well. I have been using WiFiExplorer for I think 4-5 years.
Besides scanning networks, you can read the Ins (Information Elements) if the beacons under the “Advanced” tab, you can find hidden network. You can switch between Passive and Active scanning. The displays filters are great and super useful for finding things quickly.
As a wireless professional, WiFiExplorer is one of my main GO TO tools. For quick analysis of the environment I pull out WE first on site. With the Pro version (which I use) you can even performe Spectrum Analysis using 3rd party hardware devices such as MetaGeek's WiSpy. This is truly a professional tool. Even the Standard version of WE is a fantastic tool.
Lastly, the developer of this app is SUPER responsive - adding featuers and fixing (the few) bugs that inevitabley come up on a consistent basis. For quick, PROFESSIONAL analysis, cannot go wrong with this app.
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.
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: https://www.adriangranados.com/blog/dbm-to-percent-conversion
With Family Sharing set up, up to six family members can use this app.
