Which is Better, Mesh WiFi or a Router?

A router usually cannot cover every corner of a house, leaving many spots with poor WiFi signals. If you extend its coverage with other devices such as extenders, they set up separate networks, causing dropped connections when you switch networks or keeping you connected to a weaker signal.

Mesh WiFi is ideal for whole home coverage. It uses multiple nodes working together to form a unified network through your home, and automatically chooses the best node and band for your data. You can enjoy uninterrupted streaming even when you move around your home. What’s more, you can easily extend WiFi coverage whenever you need. Simply add new mesh units and the system will automatically sync settings to them.
