In the Firmware Upgrade section, to upgrade your firmware, click Browse, locate and select the firmware image on your host, and click Upgrade. After the new firmware image is validated, the new image is written to flash, and the router is automatically rebooted with the new firmware. The Firmware Information and also the Status > Device Info > Device Status page will reflect the new firmware version.  IMPORTANT! During firmware upgrade, do NOT try to go online, turn off the DSR, shut down the PC, or interrupt the process in anyway until the operation is complete.

Interrupting the upgrade process at specific points when the flash i s being written to may corrupt the flash memory and render the router unusable without a low-level process of restoring the flash firmware (not through the web GUI). 128
