Introduction
Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory.

can be changed by either the manufacturer or the user as bugs are fixed or new features are added.
Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few minutes
by using the following procedures.
