Test WI-FI Strength

To measure Wi-Fi signal strength on your phone or tablet, you can use the Airport Utility App for iPhone and iPad, or Wi-Fi Analyzer for Android

Both are easy to use and show results for any wireless networks in your area

On the App you are looking for dBm

The scale runs from -30 to -90

If you see -30, you have a “perfect connection,” and likely, are standing next to the Wi-Fi router

However, if you spot a Wi-Fi signal listed at -90, the service is so weak you probably can’t connect to that network

An excellent connection is -50 dBm, while -60 dBm is likely good enough

Stand at the location you would like the controller to be and see what results you get
