Netgear also recommends the best channel configuration that you should tune to. The Network Status and Channel Interference display what networks are in reach and whether they interfere on any of the available channels.

In this way you can easily convert this data into a mental/visual representation of how the waves behave. The readings will be noted in their respective entries. You can set up entries for different areas of your home (or office if you like) and perform tests for each. There isn't much else an app can do, however, Netgear features a very useful notepad. You can also set for how many seconds the app should scan. The main screen gauges the signal with a much higher detail. Netgear Wifi Analytics provides a bit more insight into how WiFi signals work locally. However, there must be an easier method to do it than walking around with pen and paper while staring at your phone's WiFi signal strength lines. Deciding on a better position for the router is not generally that hard. Too many corners may prevent the totally safe waves from reaching the most important areas of your home, such as the bathroom or bedroom. WiFi Signal Strength Explorer is a handy little utility which unlike the normal WiFi icon, shows you the strength of connection via dots/percent in the menu bar and by clicking it, you can access some basic details about your current network.Walls can be too big an obstacle for short range radio waves such as ones emitted from WiFi routers. But it also comes with a downside which is it will also disconnect you and you have to reconnect again. JamWiFi is another free little tool which can not only analyze devices connected to your wireless network, but you can also disconnect them from using your WiFi. While normally you’d need an external WiFi adapter to these kinds of things, most Macs have a network card that supports monitor mode which overall works out pretty well. WireShark is also capable of working in monitor mode, thereby letting you see what other devices are browsing/watching on your network. Although it comes with a steep learning curve, it is one of the best packet analyzer apps available. WireShark is an open source and very powerful network analyzer used mainly by network admins and developers.
