WiFi Analyzer: Universal Windows 10 app available in Preview form
WiFi Analyzer works on PC, tablets and phones
The app is now available in a preview state for all Windows 10 devices including smartphones and tablets. WiFi Analyzer turns your device into an analyzer for wireless networks, so you can identify potential problems like what is interfering with your router.
You can also use the app to place your router in the best possible position in the building.
WiFi is currently free, but the developer could make it paid or ad-supported once it drops the preview tag. You can try the tool after downloading from the Windows Store.
