Wifisolitions.com have launched a really useful free app on Google Play called WiFi Heatmap, that gives you a great little map showing the strength of wifi coverage around your home or office.

It will show the signal level, the link speed, if there are any interfering networks that may be causing issues for your connectivity, and the coverage map(assuming you can load-up a floorplan of your house or business).
From this, you’ll be able to see which rooms of your house, or office, have good or bad signal in easy-to-see red, yellow, or green patches.

The app helps you manage your router, find out your sync speed, and gives you additional tools to maintain the best Wi-Fi signal between your router and devices. To download the app, go to the Google Play store https://play.google.com/store/apps/details?id=ua.com.wifisolutions.wifiheatmap.

If you want some help to improve coverage, then contact NTEC for a no-pressure/impartial chat.
