How to Identify an Internal Modem

A modem is a device which breaks up digital data and sends it over cable or phone lines at specific frequencies that allow modems on the other end to recreate the data. Internal modems are modems installed inside a computer's case. (External modems are modems that are self contained and connect to the computer with a cord.)

Things You'll Need

• Screwdriver(s)

Instructions

Check Modems in Device Manager

1. Click "Start," then open "Control Panel."

2. Double click "Administrative Tools," then double click "Computer Management."

3. Click on "Device Manager," and wait a few seconds. A list of devices installed in your computer will appear.

4. Search the list for "Modems," and click the plus (+) sign next to it. A list of your computer's modems will be displayed. Right click on any specific modem, and select "Properties" to bring up more information, such as driver versions and date. If you are looking to identify an Ethernet adapter or wireless card, they will be listed under "Network Adapters," instead of "Modems."

5. Right click on any modem and select "Update Driver." If you haven't updated your driver software for a while, it is a good idea to attempt to install new updates.

Open the Computer

1. Turn off your computer and take out the power cord.

2. Open the case by taking out a few screws on the back of the case, holding onto the left case cover. Certain cases, such as those on Gateways may have easy releases systems which don't require a screwdriver.

3. Locate the modem. If you use the modem, simply look for the device with a phone line connected to it. If not, look on the back of your case at the various ports, and find the device with phone-sized ports on the back. The modem should be plugged into a PCI slot, which are toward the bottom and back of the case.

4. Remove the modem for inspection. Use a screwdriver to remove a mounting screw holding the modem in place, (this may not be necessary) and then pull the modem out of the PCI slot, using firm but gentle force. Inspect the modem's labels to identify it, then reinstall the modem by reversing the process--push it firmly and squarely back into the PCI slot and put the screw back in, if necessary.

5. Close the case and plug your power cord back in.

Tips & Warnings

• Internet connections have trended away from internal modems over time, in favor of external cable and DSL modems, which are more convenient for the users.

• Old modems often go unused and waste a PCI slot; if you need extra room for a PCI device, consider removing an old modem.
