WiFi Analyzer and Surveyor: How to monitor Wifi Networks and Create Maps

Let’s start by downloading this app from the developer ManageEngine to monitor Wi-Fi networks from here:

Before we start, let’s make a brief summary of what this application can offer us:

• Channel chart.
• Possibility of classifying the networks that have more interference.
• A graph of the intensity of the WiFi networks around us.
• Know in detail the WiFi networks within our reach.
• It works with both 2.4 GHz and 5 Ghz networks.
• Possibility of working with plans.

The first time we use WiFi Analyzer and Surveyor we will get a screen like this.

In this case, it is best to choose ANALYZER , unless the main priority for using the app is to use it with plans. Then I would click on the box below to remind you of the choice.

The next thing you ask us is to be able to use location services. In this case we give you permission since its use is necessary for it to work properly and to give us more detailed information.

Here we have the initial screen of the application.

As you can see, we started in the Channel section, and to the right we have other functions that will be discussed later. The red box in the middle will allow us to choose to be classified between the 2.4 GHz or 5 GHz networks.

Then, in the last box that I have framed it will allow us to see all the networks, the best, the ones that are good and the weak. In the image above you can see which are the best. Here it would show all available networks:

These would be the ones with good coverage:

And finally, with Channel, these would be the networks that arrive weakest at our position.

Now, if we click on the tool wheel we will see the settings offered by WIFi Analyzer and Surveyor.

Among the most important we have Scan , in case we just start the app, start scanning and Refresh Interval so that it refreshes the information every X seconds. It also allows us to share the screen we are seeing in the gallery, Dropbox or by email.

To be able to do it you would have to grant the corresponding permissions, for example the gallery needs the storage. If we click on the three horizontal lines that are in the upper left corner, the main menu will not appear.

Here we have to talk about three sections:

1. Analyzer: for the analysis of Wi-Fi networks that is where we are.
2. Surveyor: to work with plans.
3. Help: with some basic notes on the use of the app.

Now it is the turn of Interference that shows us the interferences with neighboring networks by presenting a graph.

One of the things I mentioned before is that in the different sections we could see the results of the 5 GHz networks.

Click on 5 GHz and it will make the change as you can see in the following image.

The next section of the WIFi Analyzer and Surveyor that we are going to see is Signal , which classifies networks based on signal strength.

To do the test I have chosen the 5 GHz networks that had a weaker signal. If you move your finger to the right you can see the name of other networks that do not enter by space. The last section of the Wifi Analyzer is WiFi details .

In this section, both the 2.4 GHz and 5 GHz networks appear, in addition to their channel, MAC, etc. From my point of view it would not have hurt if they added a way to classify the results. To finish with WIFi Analyzer and Surveyor, now it is the turn of the Surveyor section and to be able to work with plans.

If we click on Add Plan we can start working. We have the possibility to use jgp file and other extensions, in addition to downloading it from Dropbox or creating our own plan. Finally, here we have an open plan.

Above we select the network that we want to include and we press in a sustained way in the area where that router or equipment is located.

As you have seen, this application provides us with a lot of information about Wi-Fi wireless networks, and it also allows us to upload floor plans to create WiFi heat maps, where we can easily see the coverage we receive on different devices.
