I just mentioned it in another thread but thought this useful tool might warrant a separate post. HeatMapper is a tool that can generate a map of the WiFI signal strength in your home/office etc. It runs on Windows and the basic version is free. There is also an Android version but that one you have to buy. http://www.ekahau.com/wifidesign/ekahau-heatmapper All you need is some ground plan/sketch of the area you want to check. Then you just walk around and point your positions on the plan. It has been around for a few years, so some of you might already know it. I have found it usefeul in the past to get an objective view of the WiFi in my home. It helps identifying weak spots or signal disturbances like a neighbor's WiFi for example. It is also great to find out if the WiFi on your new device is better or worse than your old one.
