Useful!

Honestly, this is one of the most useful things I have ever downloaded!
Not only does it show all wi-fi routers/networks in your immediate area, you get SSIDs and MAC Addresses of those devices. It shows what GHz band said networks broadcast on, and what b/g/n mode they use.
Its graphical displays/charts are amazingly handy and easy to understand, even if youre of a less-technical ilk.
So far, Ive been using this app to help not only my personal network, but my girlfriends network get up and RUNNING! So long as you know how to change the settings on your own router, you can use the information this app collects to work around all that interference that may be causing your wi-fi to be dragging!
Simply: its amazing.
Thank you, AccessAgility! Thank you, iTunes!
