After extensive research and cross-referencing with D-Link’s official FTP servers (which are often deprecated), the latest stable firmware for the C1 variant is:
Firmware Version: IN_DSL-2750U-C1_V2.10.4_11272015
(Date: November 27, 2015 – Note: This is the final official release; D-Link has discontinued support for this model.)

The D-Link DSL-2750U (Hardware Revision C1) is a legacy Wireless N300 ADSL2+ modem router designed for basic home and small office use. While it offers essential features like firewall protection and QoS, its aging firmware and limited hardware resources (8MB Flash, 32MB RAM) make it a "bare-bones" device by modern standards. Firmware Overview & Performance
Core Capabilities: The stock firmware provides integrated ADSL2/2+ support with download speeds up to 24 Mbps. It includes standard networking tools such as WPA/WPA2 security, SPI firewall, and MAC/Web filtering.
Regional Variants: Firmware features vary significantly by region. For instance, the Indian version (vIN_1.08) often lacks Static IP over Ethernet (IPoE/MER) support, whereas the Middle East version (vME_1.09 or later) includes it, allowing the device to function as a broadband WAN router. Known Issues:
Vulnerabilities: Versions vME1.16 or earlier have been flagged for OS command injection vulnerabilities (CVE-2021-3707), which could allow unauthenticated attackers on a local network to execute commands.
Stability: Users have reported occasional Wi-Fi connection drops, sometimes requiring a factory reset or "back-flashing" to older firmware versions to resolve. Update Experience
