Upgrading the firmware is almost the same thing as Flashing the modem but flashing is just the act of replacing the current firmware with a new firmware or an old one. NOTE: In some cases, upgrading your modem’s firmware could ruin the modem for life so you ought to be sure of what you’re doing.
Some internet modems do have issues with connectivity and signal strength and upgrading their firmwares is sometimes the solution to the problem. As it is with mobile phone operating systems, usb internet modem firmwares can be upgraded to make the device function better.
