IoT (Internet of Things)
IoT, short for Internet of Things, means everyday devices such as cameras, plugs, bulbs and thermostats that connect to your network.
What it means for you
These devices often get fewer updates than phones and computers, so many people keep them on a separate IoT or guest network and keep their firmware current. Our IoT guide shows how to set that up on common routers.
