1) Try removing the App DATA CACHE on the BMPRO app. DO THIS FIRST... maybe that's all you need to do.... here's the instructions:

2) Maybe the wire connection to the antenna is loose? Hmmm, along the side of the gateway box, there is a tab you 'press in' and the entire box slides the opposite direction. This allows you to drop the box down from the ceiling but will not disconnect it's attached wires. There should be 2 power, and three antenna wires. The antenna wires snap into place. Make sure they are snapped.
3) If you still haven't fixed it, I suppose you could do a factory reset on the wall panel, which is really a google tablet. That option is within the settings. After that, you would visit Google's PlayStore and reinstall BMPRO then establish your internet connection to see if that does it.
