In this article, you will learn what a good WiFi scanner can do for you and discover five great WiFi scanner Windows apps so you can say goodbye to slow speeds and mediocre signal reception.

Why Should I Use a Wireless Scanner App?

Try to remember how much your monthly Internet bill costs you. Probably more than you’d like, correct? If you’re like most people these days, you connect to the Internet wirelessly, which means that you seldom get what you’re paying for.

Yes, you might be able to reach the download and upload speeds your ISP advertises when standing right next to your router, but try to measure how fast your Internet connection is when you walk to the other side of your house or apartment. The chances are that it will be slow as a glacier.

With a reliable WiFi scanner, you can discover the source of your wireless woes and come up with a strategy how to put an end to them

Unfortunately, the WiFi signal transmitted by most home routers doesn’t travel too far. And it travels even shorter distance when it has obstructions in the way, such as walls or furniture. What’s more, your neighbor’s WiFi network and your neighbor’s neighbor’s WiFi network may have a noticeable negative impact on the strength of your WiFi signal, as well. As such, most people end up paying for an Internet they can never use to its fullest potential.

Enter the mighty WiFi scanner. With a reliable WiFi scanner, you can discover the source of your wireless woes and come up with a strategy how to put an end to them.

How Can a WiFi Scanner App Improve My Signal?

Wireless scanner won’t improve your WiFi signal strength on its own, but it will give you all the information you need to either pick a better place for your router or make a suitable adjustment to your router’s settings.

  • Router placement: You want to place your router somewhere from where it can cover your entire home with an evenly strong wireless signal. A wireless scanner can make it instantly obvious which places work and which don’t. Without a WiFi scanner app, you could spend hours or even days taking your router from place to place, trying to take your WiFi signal from one bar to five.
  • Router settings: The 2.4 GHz WiFi frequency range, which is the range most home routers use, is divided into several channels. When multiple routers transmit on the same channel, traffic congestion may occur and bring everyone’s speeds to a crawl. To prevent this from happening, you should switch your router to a channel that doesn’t see much traffic. Even a free WiFi scanner app can help you analyze wireless channels and select the optimal channel for your home router.
