In the new window, you will see the MAC address of the Modem and the IP address of the PC you are using. The PC and the Modem must be on the same subnet for the upgrade to be completed. The upgrade utility will suggest a new IP address to be temporarily assigned to the device during the firmware upgrade procedure. Check the suggested IP address listed for the Modem to be sure that it does not conflict with any existing IP addresses on your network. To change the temporary IP address of the Modem, type in an available IP address in the space provided. You should change only the host portion of the address.
To upload the new firmware to the selected Modem click the ‘Upgrade’ button. The utility will automatically load the new firmware. During the upgrade process it is important that you allow the entire file to load onto the device. Do not turn off the Modem while the flash memory is being updated. A warning will appear during the upgrade reminding you not to power off the device.
When the new firmware has been successfully loaded a new window will inform you of the upgrade and tell you that the Modem has been restarted. Click OK to proceed.
