Update Firmware
Click Firmware and the right page appears. In this page, you can update the router
firmware. Click Browse to find the right version file and click Update Software to
update.
Note: Do not turn off your modem during firmware updates. When the update is
finished, the modem reboots automatically. Do not turn off your modem
either before the reboot is over. You must guarantee the update software is
right and accurate. It is strictly forbidden to use other software for updates.
After update software, it is suggested to restore the router to the factory defaults and
configure it again.
