Useful, good app.

I reviewed this once before but feel I should review the new version.

The bugs seemed to of been fixed. The only thing I can see that could be worked on a little more is the viewing locations of the wireless routers. Some show up in the correct location on Google Maps, but for my own router which was installed with the phone line yesterday, Google Maps is showing that my router is somewhat 250 miles away.

Great app that saved me a lot of hassle

I had the problem recently that my Wifi stopped working at home. I assumed this was because someone in the area set up a new base station that overpowered my little base station, but I had no tool to check this.

I found this app via a Google search, installed it on my MacBook Pro (Jan 2013 version) and it works absolutely perfectly. I found all the other base stations and the channels they are on and managed to find myself a channel that was not so congested. Now my WiFi works again.

Very happy with this product.
