D-Link has largely removed old firmware from their official sites. If you are looking for a or alternative firmware:
This is where the "ME" region firmware shows its age. dsl-2740u firmware version me-1.03
Firmware from the era of ME-1.03 (typically dating back to the early 2010s) lacks support for modern security protocols. For instance, the administrative interface likely supports outdated encryption standards and may be vulnerable to common exploits such as DNS rebinding or authentication bypass attacks that have been discovered in the years since its release. Furthermore, the firmware does not support modern Wi-Fi security standards like WPA3, leaving wireless traffic susceptible to interception. The existence of "ME-1.03" serves as a case study in the importance of firmware updates: once a manufacturer ceases support—as D-Link has for this legacy model—the device becomes a potential entry point for malicious actors, regardless of how well it routes traffic.
