What are the lights on a Modem / LAN Card?
A modem or a LAN card is primarily used to connect the computer to the internet. While each modem and LAN card might differ depending on type, make and the manufacture, most of them tend to have at least four of the following lights in common.
- Power Light: Shows if the device is on or off
- Link Light: Shows if the device is getting broadband/internet signals from the ISP
- Data Light: Shows whether the internet is working or not.
- Connectivity Light: Shows whether the Modem is connected to a computer or not.
