WiFi Monitor

Before this app I would occasionally lose wifi, As I understand there are 14 channels you can set your router to, this app showed me the best channel to use resulting in a great steady signal.

Straight forward information.. very useful in checking the strength of your router.. also lets you see who else is on your wi fi band

I have tried this type of app before and every one of them has been off by a mile. I normally test at three different places and this app hit the nail on the head.
