3.1 Overview

Use the Firmware Upgrade Tool to ensure you have the latest firmware (version
3.3.4 or later) on your PLA-401 Series(s).
You need to upgrade all your PLA-401 Seriess to the latest firmware to ensure
they can connect with each other and they are compatible with the latest version
Utility.
If your firmware is an early version (earlier than 3.3.4), then upgrade your
firmware using the Firmware Upgrade Tool.

3.2 Firmware Upgrade Tool

Use the firmware upgrade tool to upgrade your PLA-401 Series's firmware to the
latest version.
You can use this tool to upgrade the firmware on the powerline device directly
connected to your computer. This is necessary as devices with ZyXEL's early
version firmware are not compatible with the latest Utility or with devices running
ZyXEL's latest version firmware.
At the time of writing, firmware version 3.3.4 is only available to PLA-401 Series.
Note: The firmware is included in the Tool. You do not need to download the firmware
separately.
