What you need
• Your Internet access account details from your ISP - this is important as
you will need to have the login details from your ISP after the firmware
upgrade.

Important notes
• Only upgrade if necessary – if your router is working without any problems,
we will recommend you to stay with the existing firmware. There are always
risks that the router might not work if the firmware upgrade failed.
• Always use a wired Ethernet connection – a wired Ethernet connection is
highly recommended when performing firmware upgrade to minimize possible
interruptions.
• Do not disturb or power off the router during firmware upgrade – if the
firmware upgrade process was disturbed you will end up having a dead router.
• Turn off any firewall or Internet security software – as firmware upgrade
process involve uploading the firmware file from your computer to the router,
it is best to turn off any firewall or Internet Security software to avoid possible
conflicts. Please refer to your software supplier on how to turn the software off.
