Excellent Utility every WifFi user should have

This application is almost identical to a Windows application named "inSSIDer".

It gives you a clear picture graph view of which channels are being used by other WiFi access points in the area, and their relative signal strength. This will help you pick the best channel to set for your WiFi router, and do a better job than the "auto" channel selection feature of most routers.

The ability to watch and/or log WiFi information over time allows you to deal with interference issues that may not exist at every moment in time. I used this program to solve a problem with the free WiFi at my local coffee shop. Their WiFi would become unresponsive several times per week to several times per day. By monitoring their WiFi environment over time, I learned that another WiFi access point was popping up occasionally, using the same channel and having a strong signal. This would knock the coffee shop WiFi offline until they rebooted their router. In other words what looked like the best channel most of the time, would become an unuseable channel when this 3rd party access point would kick in. Using this information I switched to the coffee shop router to a different channel, and they have not had a problem since.

One suggestion to make this program even easier to use, is to incorporate a feature offered by a program also called "WiFi analyzer" that is available for jaiil broken iPhones. That program has a simple info page which gives a 1 to 5 star rating to each available channel, the 5 star ratings being the most recommended channels for you to use.

It is unfortunate that to use a tool like this on the iPhone one can not do so through the official app store.
