  • Point of purchase or system manufacturer (internal modems) – this recommendation is the easiest way to identify the modem manufacturer.
  • Product packaging: Look for the manufacturer on the box the product came in.
  • Documentation: Look at the instructions or literature that came with your modem. If the modem is internal (inside your system), look for the system manufacturer.
  • The product markings can include the name of the manufacturer, or look for an FCC ID number or other number from a regulatory agency.
  • Regulatory agencies such as UL, CSA, or FCC database* or Equipment Authorization System can help, given a reference or certificate number.
  • Modem Properties – look in CMOS or BIOS information. The modem manufacturer can also be under Modem Properties displayed in System Information under Operating System Accessories or System Tools.
Note This method can result in identification of the chipset and not the actual modem manufacturer.
