Setting up ADSL Modems/Routers

What is a Modem?

A modem links your home network to the Internet through your Internet Service Provider (ISP). The high speed types of data outside of your home are not suitable for your direct use, so modems convert the data into digital Ethernet, which all the network equipment in your home can use. A modem (modulator-demodulator) is a device that modulates an analogue carrier signal to encode digital information and demodulates the signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. The most familiar type is a voice band modem that turns the digital data of a computer into modulated electrical signals in the voice frequency range of a telephone channel. That is the Technical explanation.

The Simple Explanation: The modem converts the signal on your telephone line to Digital Data.

What is a Router?

A router is a small box that allows multiple computers to join the same network. While early routers provided several Ethernet ports for wired connections, most modern routers offer wireless connectivity as well. These wireless routers or WIFI, often have one or two moveable antennas on the sides, though some models house the antennas inside the enclosure. Wireless routers allow multiple computers and other devices, such as smart phones, tablets and printers to join the same network.

While connecting to a router provides access to a local network (LAN), it does not necessarily provide access to the Internet. In order for devices on the network to connect to the Internet, the router must be connected to a modem. Therefore, most routers have a specific Ethernet port (WAN Port) that is designed to connect to the Ethernet port of a cable or DSL modem.

The modem connects to your ISP, which typically provides your ADSL Service or in some cases a Cable service. Cable modems have a coaxial (or "coax") connection, which is the same type of connector found on a TV or cable box. This connects to a cable port on the wall. ADSL modems have a telephone connector, also called an RJ-11 jack, which connects to a telephone socket on the wall, through a filter.

The router and modem can be separate units. However, today, modern units combine the modem and router into one box. All devices connected to the router can access the modem, and therefore, the Internet. The router provides a local IP address to each connected device, but they will all have the same external IP address, which is assigned by your ISP.
