Say what a hub is for
Why some devices need a small box and others do not.
A hub is a small box that speaks to devices which cannot reach your Wi-Fi, and passes their messages on.
Plugs and cameras usually need none. Small battery sensors and some bulbs do.
Key points
- A hub carries messages for devices that cannot join your Wi-Fi
- Wi-Fi devices work whether the hub is plugged in or not
What to remember
- A hub is a middleman, not a boss.
- A hub matters to the devices that speak through it.
Try this
Look behind your router for a small box with a cable into it. Usually the hub.
