Ensuring the modem is connected properly.
Cause:
A modem that is not connected properly will cause the modem to not operate properly or not work at all. This could cause the computer to generate errors or not be able to connect to the Internet or other computers.
Solution:
It is common for modems to not be connected properly either because of improper set-up, a cable becoming loose, or someone disconnecting the cable to be used elsewhere. We have listed several items to check to help ensure that the modem is properly connected.
Two Phone Holes – The majority of modems today have two phone holes that allow a phone connection to be connected. Connecting the modem to the improper hole will cause the modem to not work. When inspecting the back of the modem you will commonly have either text indicating what each hole is and/or a picture of a phone or modem. Almost always the cable coming from your wall should be connected to the ‘line’ or ‘line in’ hole or the hole that does not have a picture of the phone next to it. The other hole allows the user to connect a phone to the back of the computer to also have a phone next to the computer; this can also be used to check for a dial tone.
Type of Hole – The standard phone hole for a modem is referred to as a RJ11 connection. Many computers today also include a network card, which utilize a RJ45 connection, which is extremely similar to the RJ11 connector, but is slightly bigger. Ensure that if you have a Network Card and Modem that you are connecting it into the correct hole. In addition make absolutely certain that you have a modem in the computer and not just a network card. A lot of times the computer may not have a modem.
