Full Answer

Modems have other lights, besides the Ethernet link light, that can help one figure out whether or not the modem is working properly. There is a light to show that the modem is turned on and has power and a light for the Wi-Fi connection. Most modems also have a light to show whether or not the modem is online or offline. This is necessary because even when a modem is connected via Wi-Fi, it is possible to not have Internet access.

A modem is a device that is most commonly found in the form of a tiny black box. It can use dial-up, DSL or cable to connect a person's computer with the Internet. A modem works by translating data sent to it to display that data on a person's computer. The computer information will be stored digitally even though the information comes from analog waves. The modem makes it possible to surf the web, play games online and check out the latest news on Facebook. When choosing a modem, it is always necessary to choose a modem that is compatible with the home computer, has good upload and download speeds and that has security support features.
