Important
–
Do not change the file extension (.cdi) of the router firmware files as this can cause the firmware upgrade process to fail.
Back up current settings (optional)
NTC-220 Series routers and their firmware upgrade files are designed to retain your existing settings throughout
the upgrade process. Strictly speaking, you do not need to back up your current settings prior to the firmware
upgrade.
However, it is recommended that you back up your settings on a regular basis in case of damage to the router or
an unexpected interruption during the firmware upgrade process.
