The first stop for the internet connection once it reaches your premises is usually a unit called a ‘router.’ This is the central master ‘hub’ that sends the internet connection onwards to all of your devices that need it.

Devices can connect to the router using a physical cable, but it is often more convenient to use a wireless signal called Wi-Fi instead, especially if using multiple devices in a number of rooms across a location.

Some users of mobile broadband may connect to the internet using a mobile Wi-Fi ‘hotspot’ instead of a router but the same principles apply (see our quick guide to mobile and satellite internet for care providers for more information on this).
