Given the constraints, I will craft a comprehensive article. The article will start by emphasizing the critical importance of verifying the hardware revision before proceeding with any firmware update. I will explain how to check this on the device sticker or in the web interface. I will then present the firmware update link for the Rev.U2 hardware revision, along with its release notes. I will also include detailed step-by-step instructions for performing the update, safety precautions, a troubleshooting section, and final recommendations. I will base the information on the sources I have found, citing them appropriately.

Firmware updates are at your own risk. While the links provided are official D-Link sources, always re-verify your hardware revision before proceeding. This article is for informational purposes and is not an official D-Link publication.
