What's New in Version 2.3
- bug fixes
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!
Must have app if you want detailed info about the WiFi networks around you
Every Mac user should have three utilities - a duplicate file remover, a password manager, and a wifi scanner app.
When away from home, this app will find all wifi networks and list detailed signal information about each access point.
At home, use this app to discover details about your wifi and nearby interfering networks.
Use information learned from app to configure your access point for the least used channels.
Good Start - Has Some Problems
Running it on a 2012 MB Pro / 10.9
It provides lots of good information but I’m experiencing the following:
-Refresh interval not editable
-History column does nothing
-No help (what’s the “History column” supposed to do?)
Goes unstable after running for a while (hours)
-Menu options grayed out (can’t quit - force quit required)
-Clicking controls / buttons does nothing
Given the price I can’t complain too much but I expect better quality from a Mac app.
Like it - looking forward to the update(s)
