ModemA modem is a device that connects to a broadband internet service provided by a telecoms company, using either an ADSL or cable connection.
The modem acts as a local gateway between your home or office, and the internet service provider. You will need to buy the right type of modem for your service, cable or ADSL. Check with your ISP if you are not sure which you need.
The major consideration when buying a modem, is whether you also need it to function as a router, either wireless or wired.
Modem/RouterA modem that also has a router function, is capable of sharing the incoming internet connection with a number of devices. If you have ever connected to a Wi-Fi hotspot, or plugged a cable in to your laptop at work, then you have used a router.
Combining modem functionality with a router, is a very cost effective way to set up a home or small office network with internet access. Modern modem routers are reliable, fast and very easy to set up.
A modem router will either have Wi-Fi capabilities, hardwired ports, or a combination of both.
