DO NOT power down the rout
er or interrupt the firmware upgrading while
it is still in process. Improper operation could damage the router.
Firmware Upgrade
Your router’s “firmware” is the software that allows it to operate and provides all its functionality. Think of
your router as a dedicated computer, and the firmware as the software it runs. Over time this software may
be improved and modified, and your router allows you to upgrade the software it runs to take advantage of
these changes.
Clicking on
Browse
will allow you to select the new firmware image file you have downloaded to your PC.
Once the correct file is selected, click Upgrade to update the firmware in your router.
It is recommended that firmware upgrade should only be undertaken using a wired LAN connection,
preferably with the PC directly connected to a Router LAN port. Software firewalls on the PC should be
disabled while upgrading to prevent any interruption to the process. Disruption of the process may render
the Router unusable.
