Useful utility


This was very helpful for setting up and placing a Wi-Fi access point and a power line Wi-Fi extender in my house. I took before and after measurements when I installed new hardware so that I could be sure the new equipment was working and that the dead spots were taken care of. 4 stars instead of 5 because: 1.) I would like to have a choice of multiple servers for the speed test so that I could choose the fastest for my location so that hopefully server issues would be less likely to have an effect on my measurements; 2.) It would have been helpful to have a comment field for the speed test (it does have a comment field for the strength test), so that I could make a note to indicate the locations of my measurements. I used the Excel app to make a spreadsheet instead. I consider these minor issues that the author may consider for future enhancements. For a free app this is a great help for DIY'ers setting up a home Wi-Fi network.

This app works very well in a situation where you have limited control, for instance where you are dependent on a landlord supplied access point and router. I moved from a house where I set up my own LAN and could buy my own router to a senior living environment with a MAC filtered WiFi internet access provision and had to argue with the IT dude about the poor WiFi signal down at the -75 dbm level. (-45 would be good).
If you are just picking optimum locations for a router and boosters this APP also works very well. Also it’s free. Highly recommend for either technical or nontechnical folks.

Great UI and super useful


Easy to use with a great interface that includes helpful tool tips to explain the readings. Much appreciated. For the signal strength screen, it’d be nice if the info in the tooltip was on the screen itself. I found myself having to check the info in the tool tip a few times to remind myself what signal strength number I was searching for. It was great having that info in the app instead of a separate website but it’d be even better if it was on the same screen for quick comparison while searching for the right signal strength.
