Hey, I totally get the frustration of weak WiFi signals in certain areas of your home. A WiFi heat map can really help you pinpoint where the problems are and find solutions. There are some great free tools out there that can help you create a WiFi heat map for this purpose.
First off, I recommend trying NetSpot. It’s a popular tool that’s very user-friendly, even for non-tech savvy people. It offers both a free and paid version, but the free one should be sufficient for generating a heat map of your home. You just walk around your space with your laptop while it’s running, and it collects all the data you need to visualize the weak and strong areas of your WiFi coverage.
There are also other apps like WiFi Analyzer and Ekahau HeatMapper, but in my experience, NetSpot is the easiest to use and gives a clear, visual representation of your WiFi coverage. It's also frequently updated, making sure it stays compatible with the latest systems and standards.
To sum it up - if you’re looking for a free tool to create a WiFi heat map, definitely check out NetSpot. It’ll help you identify dead zones and optimize your network to ensure better coverage throughout your home.
