Preparation
Before You Connect with Your Smartphone
Monitor and control your garage door from anywhere using the myQ
smartphone or other mobile device. Make sure your mobile device is connected to your Wi-Fi network. Hold your
mobile device in the place where your garage door opener will be installed and check the Wi-Fi signal strength.
Check Signal Strength. If you see:
Wi-Fi signal is weak.
The garage door opener will likely connect to your Wi-Fi
network. If not, try one of the options below.
No Wi-Fi signal. Try one of the following:
• Move your router closer to the garage door opener to
minimize interference from walls and other objects
• Buy a Wi-Fi range extender
• Buy an Internet Gateway (828LG) see page 41
