Once you install Plume's smart Wi-Fi products throughout your St. Louis home, you won't want to rely on a single router again. This adaptive technology streamlines your internet connection and enhances your peace of mind.
Experience Consistently Fast Connections
Through Adapt™, our whole-home Wi-Fi solution continuously studies your usage patterns, predicts where you need the strongest signal and adjusts to optimize performance. It also adapts to your connected devices to ensure smooth connections.

Thanks to Guard™, our smart Wi-Fi solution filters suspicious activities and ads, safeguards your smart home devices and provides online protection. It automatically isolates devices behaving suspiciously from your home network and the internet.
Get Better Home Awareness — No Extra Hardware Needed
Sense™ turns your existing smart devices into motion sensors for improved home awareness. Receive motion alerts when you are away and calibrate your solution to ignore your pet's movements.
Gain Full Performance Visibility From a Single App
View your entire network and devices on the intuitive HomePass® app. Easily monitor speeds and overall performance from the convenience of your phone.
Installing Whole-Home Wi-Fi Solutions in St. Louis
Setting up your efficient Wi-Fi solution starts with fiber internet and a home network modem. Our experts will then help you determine how many Plume devices you need to ensure smooth connectivity throughout your home.
