Why your smart devices keep going offline (and how mesh Wi-Fi helps)

Robots, cameras and smart plugs use small radios that are sensitive to weak signal. Here's what usually goes wrong.

Distance and walls

Brick, tile, mirrors and floors absorb Wi-Fi. A single router in a corner rarely covers a two-story New Jersey home.

Most smart devices only use 2.4 GHz. Some routers merge bands in a way older devices dislike; a dedicated IoT network fixes this.

Mesh systems place two or three nodes around the home so every room gets strong signal, all under one network name.

We measure signal in each room before recommending equipment, so you don't overspend. See our Wi-Fi service.
