In this article, we go over the most typical use cases for WiFi scanner apps. We also describe the most important feature a WiFi scanner app can’t be without. Finally, we recommend five excellent WiFi scanner apps so you can optimize your home wireless network right after you finish reading this article.

Why Should I Use a WiFi Scanner App?

We live in the era of wireless communication. Most modern electronic devices are WiFi-enabled, constantly sending and receiving packets of information to offer users interesting and useful features, to stay up to date, and to help manufacturers learn more about the likes and dislikes of their customers. Likewise, we have gotten used to accessing the web and conversing with our friends and family from anywhere and at any time.

Even though our lives now depend on wireless Internet access and its quality, we seldom bother to do anything to improve it. We defeatedly accept having a strong WiFi signal on one side of the bedroom but not on the other side. And we don’t even consider that online videos could load just a fast when our neighbors are at work as when they are at home, also streaming high-definition movies and TV shows.

Wireless scanners show what exactly must be improved to achieve shorter loading times and better coverage

Wireless scanners are an antidote to this passive attitude. They show what exactly must be improved to achieve shorter loading times and better coverage. Some do this for free, while others cost money. Some target home users, while others are designed for network professionals and IT experts. But despite their differences, all wireless scanners make it easier to understand why it sometimes takes just a few steps in the wrong direction to go from five bars to only one or none.

If you’re currently unsatisfied with the performance of your home WiFi, or if you would like to extend your WiFi coverage so that no room in your home is without WiFi, you need a WiFi scanner app. More specifically, you need a WiFi scanner app that fits your needs and your expertise level. In the next section, we cover some of the most important features that every good wireless scanner app should have.

What Features Should a Good Wireless Scanner App Have?

A good wireless scanner app is easy to use. Just because a wireless scanner app has advanced features aimed at professionals and experts doesn’t mean that its user interface has to be grossly outdated and mindbogglingly unintuitive. When developers take the lazy road and force users to study lengthy manuals just because they couldn’t make everything obvious without them, it says a lot about their attitude toward their customers and toward the software they are making.

A good wireless scanner app supports all modern WiFi standards

A good wireless scanner app supports all modern WiFi standards. While your home router may have a yellowish tint due to its age, Wi-Fi Alliance has been actively improving the WiFi technology to achieve wider ranges, fewer problems with interference, and faster speeds.

Just because your router doesn’t support the latest WiFi standard doesn’t mean there aren’t other routers nearby that do. With a good wireless scanner app, you will be able to detect them all and see how they could affect the performance of your wireless network.

Finally, a good wireless scanner app is developed by a team of experienced developers who stand behind their product and frequently release updates and bugfixes to make it even better. With these criteria in mind, we’ve select five WiFi scanner macOS apps for your convenience.
