You’ve been using a computer to surf the ‘net, but it has suddenly stopped all communication over the network. When you look at the network connection, you don’t see any status lights. What is the most likely cause of this issue?
A) The network adapter is disabled
B) A network driver is conflicting with another component
C) Your computer is infected with malware
D) The network cable is physically disconnected
E) Your computer thinks you need to go outside and take a walk
The answer: D) The network cable is physically disconnected
There are often two status lights on a network adapter. One usually shows the existence of a physical link, and it will be lit if the adapter is enabled and a signal is detected. The other status light usually blinks as traffic is sent or received across the network.
