Other methods of determining the modem type

  1. One of the best methods of determining the modem within a computer is to physically inspect the modem. On the majority of modems you will be able to determine the manufacturer, model number, and speed by opening the computer and physically looking at the modem.
  2. If you are unable to locate a manufacturer or model number of the modem, but are able to locate a FCC identification number, it is recommended that you perform a FCC search using that number. Additional information about FCC numbers and how to search for information about a FCC number can be found on our FCC dictionary definition page.
