![]() ![]() Also moving the AP up from the floor and positioning antennas vertically (in case of moveable antennas) can change the situation to the better. Is there a concrete wall or a large metal cabinet or a fridge that is blocking the signal from access point? Something like this can be fixed by simply moving the access point further along to the other corner. For example, when the signal is weak off the particular side of the AP, examine the structure of the building in that direction. Move the Access Point: The first thing to try, and the easiest, is moving the access point around. Studying the heat map thoroughly helps you see the weaknesses of your WiFi coverage and gives an idea where to start to fix the issue. Now that you have a WiFi heatmap of your home or office you can take every benefit out of it. Studying the heat map thoroughly helps you see the weaknesses of your WiFi coverage At the very least, create one WiFi heatmap before deploying a new access point or changing the configuration/location and one after. Create multiple WiFi heatmaps: Since WiFi heatmapper tools like NetSpot can create a comprehensive WiFi heatmap in just a couple of minutes, depending on the size of the surveyed area, you shouldn’t hesitate to create multiple WiFi heatmaps so that you have plenty of information upon which to base your decisions.This is especially important when measuring the coverage of a mesh network, which may consist of dozens or even hundreds of wireless mesh nodes talking to one another. Mark all AP locations: It may seem trivial, but experience tells us that people often forget to mark the exact locations of all access points when creating a WiFi heatmap, only to later struggle when interpreting the results.Instead, measure during regular work hours so that you can see what the worst-case situation looks like. If you want to, for example, cover a large office with a strong WiFi signal, it makes little sense to measure after work, when everyone’s at home and there’s far less radio frequency interference. Know when to measure: Your measurements should reflect real-life conditions as closely as possible.The good news is that learning this skill can be easy-you just need to pick the right WiFi network scanner. With WiFi connectivity becoming increasingly ubiquitous and integrated into more and more devices and appliances, knowing how to use a WiFi scanner to optimize wireless performance is quickly becoming an important skill to have. Since NetSpot is a software scanner, we’ll be using the term WiFi scanner to describe software scanners.Īs will become obvious later in this article, many leading WiFi scanners are so intuitive that even people with no previous experience with them and little to no technical knowledge can use them to discover causes of WiFi issues, such as co-channel interference and poor signal coverage. In terms of features, however, software scanners typically exceed hardware scanners, and the same can be said about their ease of use. Because different laptops and mobile devices have different WiFi modules, the same software scanner may provide vastly different results when used on two different devices. Software scanners On the other hand, software scanners depend on a laptop or mobile device and its WiFi module.Hardware scanners are most commonly used by technicians in the field because they free them from having to carry a heavy laptop with limited battery life. Hardware scanners: As the name implies, hardware WiFi scanners are physical devices, typically of the handheld variety.WiFi scanners can be divided into two categories: The collected information includes everything from network names and their security settings to signal strength, noise level, interference, and more. The purpose of a WiFi scanner is to discover all nearby WiFi networks and collect as much information about them as possible. ![]()
