Using WiFi Scanner you’ll see nearby wireless access points and their details, including channels, signal levels (RSSI), noise, channel width, and MAC address, signal quality, maximum data rate, encryption, and much more. Also includes upload and download speed testing to quickly measure and analyze WiFi Internet performance problems.
“…your wireless router is fighting for spectrum with its neighbors, potentially slowing you down and making your Internet experience less pleasurable. ...WiFi Scanner helps you solve this problem by showing you all the access point(s) nearby, and suggesting the best configuration settings to get the most out of your router.” -- MacWorld
Simple, fast wireless network discovery of 802.11 a/b/g/n/ac access points. WiFi Scanner is great for determining the best position for an access point at home or in the office. After selecting the best position, the optimal channel to use can be determined by selecting the least used channel resulting in improved WiFi speeds.
▪ Simple, fast wireless network discovery of 802.11 a/b/g/n/ac access points.
▪ Connect to detected networks using join button
▪ Full support for both 2.4 and 5 GHz networks
▪ Support for all channel bandwidths (20, 40, 80, and 160 MHz)
▪ Display detailed wireless network parameters: network name (SSID), signal level (RSSI), MAC address (BSSID), signal quality, channel, maximum data rate, encryption, etc.
▪ Display changes in signal level over time in graphical form.
▪ Filter list of detected wireless networks by specified parameters (SSID/network name, channel, channel band, signal strength)
▪ Display wireless connection statistics in the form of graphs and tables.
▪ Give each access point a custom label
▪ Export results to comma separated value (CSV) files
▪ Generate summary reports in HTML format
WiFi Speed Testing
▪ Upload and download WiFi speed testing
▪ Use speed testing feature to troubleshoot WiFi networks
▪ Auto run speed test when client roams to different access point
▪ Auto repeat speed test with wait time between tests
"Who's On My Network" (IP Scanner)
▪ Fast IP scanner that detects unknown devices connected to your WiFi network.
▪ Detects hostnames, determines the MAC address, and in some cases can auto-detect device type (phone, laptop, router, etc).
▪ Configured icon for discovered devices is saved for future scans.
▪ Scanning results can be saved to CSV file via menu export option.
▪ Great for finding WiFi "Piggybackers".
Advanced Features (supported by some access points)
▪ Display access point name if configured by network administrator
▪ Display number of devices connected to each access point
▪ Display channel utilization
▪ Display if 802.11r is enabled and type
▪ Display if WiFi protection mechanisms are enabled

More Comprehensive, Yet Easier to Use Than Wireless Diagnostics - I had been using Apple's Wireless Diagnostics program on my laptop and was looking for more information to solve a WIFI drop problem. I already knew that there are a lot of users in my neighborhood on the 2.4GHz frequency clogging up channels 1-11. But even though I am on my own channel on the 5GHz frequency, I am still losing connection. Although I still haven't figured out what's causing the dropouts, this app gave me the assurance that I am on the right track. It is so easy to use that instantly I was able to see graphically that I had the strongest signal in the neighborhood. I like the way each WIFI network is color coded. And the ability to view or not view users allows you to compare individual networks or see all of them on the same frequency. The columns can be sorted ascending or descending, so sorting the Last Seen column will cluster the network traffic by time. The Signal Rank tab ranks the networks from strongest to weakest. If you want to graphically see how the individual networks are clustered on each of the channels, the 2.4GHz and 5GHz tabs can show you just how busy your neighborhood really is (or isn't if you are lucky). The developer also has a PDF user manual on their website. Highly recommend!
Crashes and spins - Will either crash on start up or spins during scan and never shows data. Don't bother.

Stopped working, But there is a FIX! - I guess it stopped working when i upgraded to High Sierra or catalina not sure when.. But bascially i was only able to see 1 wifi network in the scan which was odd. This app always worked beautifully before. Turns out, all you had to do was enable Location Services, unders system preferences > security > Privacy.. back to 5 stars
No longer works- limited to 1 wifi network - In the past, this app always worked perfectly, showing the details of every network my laptop could see. In the past year or so, it has changed to only showing one network at a time, and a randomly selected one at that- so it's no longer useful for finding networks, or to tell if my network is on the same channel as another network. I've waited for a couple of months for an update, hoping that it was simply a bug; but the app remains useless.
Extremely useful for diagnosing Wifi issues - This app does a great job of showing all the APs near you, along with a great deal of information about each one. It graphs out signals on both 2.4 GHz and 5 GHz bands. The interface can start off pretty cluttered with tons of SSIDs, but a little tweaking will eliminate the clutter and help you see exactly what is on each channel. A great inSSIDer alternative.
GOOD... BUT KNOW THIS... - Upon downloading it seems as though it is NOT WORKING. You MUST turn on location services under the system preferences. If you do not, you well become frustrated, like real quick.
Asked for a refund - no response - They don’t respond to their email.
